Discover the Art of Cake Decorating: Crafting a Stunning Marbled Chocolate Cake Wrap
An exclusive tutorial adapted from the highly anticipated new book, Erin Bakes Cake, by acclaimed contributor, Erin Gardner!


For years, it has been an absolute delight to share innovative, accessible, and utterly delicious cake design projects with the vibrant community here on The Cake Blog. Now, with immense excitement, I am thrilled to offer you a glimpse into my latest creation – my new book, Erin Bakes Cake! This special feature combines two captivating techniques found within its pages: the elegant chocolate wrap, inspired by my Potted Orchid Cake, and the intricate fantasy chocolate flower, drawing from the petal and leaf artistry of my Spring in Bloom Cake. Instead of presenting these projects directly from the book, I’ve blended elements from both to create something entirely fresh and unique. This approach perfectly embodies the spirit of the book: to empower you to choose your own cake adventure and unleash your creative potential in the kitchen.

I genuinely hope you’ll explore its contents and find endless inspiration to whip up your own magnificent culinary creations!

The Versatility of Chocolate: Endless Decorating Possibilities
One of the most exciting aspects of working with chocolate in cake decorating is its incredible versatility. Like all of my chocolate projects, both those featured in the book and shared here on The Cake Blog, you have the freedom to choose between regular chocolate or coating chocolate for both the elegant wrap and the delicate flower. Coating chocolate, often referred to as candy melts, is a fantastic option for beginners as it eliminates the need for tempering, making the process smoother and more forgiving. Regular chocolate, when tempered correctly, offers a luxurious snap and sheen that is truly unparalleled. Whichever you choose, the results will be stunning!
This tutorial provides a clear path to recreating this exquisite Marbled Chocolate Wrap Cake exactly as presented. However, I wholeheartedly encourage you to take my lead and embark on your own unique cake adventure! Imagine changing up the colors in the marble wrap; you could opt for sophisticated natural marble tones like grays, blacks, and creams for a truly elegant finish, or go wild with a whimsical rainbow effect for a fun, celebratory vibe. The possibilities are only limited by your imagination. Similarly, the versatile petal technique demonstrated here is perfect for crafting a wide variety of flowers with pointy tips. Think beyond the fantasy flower and create stunning chocolate poinsettias for the festive holiday season, or elaborate dahlias that will impress at any autumn gathering. These techniques are sure to become staples in your cake decorating repertoire, perfect for all your upcoming holiday desserts and special occasions!

Step-by-Step Tutorial: Marbled Chocolate Wrap Cake with Fantasy Flower
This detailed guide will walk you through the process of creating a breathtaking marbled chocolate wrap and a complementary fantasy chocolate flower, transforming a simple cake into a masterpiece. This exquisite project is a highlight from Erin Bakes Cake by Erin Gardner.
Essential Supplies You’ll Need:
- 6-inch Round Crumb-Coated Cake, Chilled: Starting with a chilled, crumb-coated cake ensures a smooth canvas for your chocolate wrap and prevents crumbs from mixing with your buttercream or chocolate.
- 3 cups White Coating Chocolate or Regular White Chocolate: This forms the base of your marble effect. Coating chocolate is easier to work with, while regular white chocolate offers a richer flavor.
- 2 cups Light Pink Coating Chocolate or Tinted White Chocolate: For beautiful, soft pink hues in your marbling and flower petals. If using regular white chocolate, ensure it’s properly tinted with oil-based food coloring.
- 1 cup Dark Pink Coating Chocolate or Tinted White Chocolate: To add depth and contrast to your marble pattern.
- Acetate Sheet: Crucial for creating a smooth, removable chocolate wrap. Ensure it’s food-safe.
- Ruler: For precise measurements of your acetate sheet and foil.
- Scissors: For cutting acetate and foil.
- Heavy Duty Aluminum Foil: Used to create molds for your chocolate petals.
- Small Knife: Ideal for spreading chocolate for petals and scoring the chocolate wrap.
- Small Bowl: For melting chocolate and assembling the flower base.
- 1 cup Clear Sanding Sugar: Adds a beautiful sparkle and texture to the top of your cake.
- 2 tablespoons White Nonpareils: Small, round sprinkles for added decorative detail and contrast.
Part 1: Crafting the Delicate Chocolate Flower
We begin by creating the stunning chocolate flower, a beautiful centerpiece for your marbled cake.
Step 1: Prepare the Foil Petal Molds. Tear off a strip of heavy-duty aluminum foil, approximately 2 inches wide. Cut this strip into smaller pieces, each about 3 inches long. You’ll need about 20 pieces to create enough petals, plus a few spares. Fold each small piece of foil in half lengthwise, then gently open them back up. This crease will act as a guide for shaping your petals.

Step 2: Create Chocolate Petals. Melt the light pink coating chocolate in a small, heatproof bowl. If you’re using tinted regular chocolate, ensure it is properly tempered beforehand to achieve the best texture and stability. Dip the flat side of your small knife into the melted pink chocolate, coating approximately 3 inches of the blade. Carefully lay the chocolate-coated side of the knife onto one of your prepared foil pieces, with the open-side of the foil facing up. Align the tip of the knife with the crease in the foil. Gently pull the knife away, smearing the chocolate onto the foil to form an elegant petal shape. You can rock the knife slightly back and forth to refine the shape and create a delicate, natural curve. Repeat this process until you have approximately 20 petals. Remember to make a few of these petals slightly shorter; these will be used for the innermost layers of your flower. Set all the petals aside in a cool place to completely harden, which typically takes about 10 minutes.



Step 3: Assemble the Chocolate Flower Base. Take a 6-inch-wide piece of aluminum foil and gently push it into a small bowl, forming a small, stable cup. Spoon a small, quarter-sized puddle of the melted light pink chocolate into the very center of this foil cup. This will serve as the adhesive base for your first layer of petals. Carefully place the flat end of one of your hardened chocolate petals into this puddle of chocolate. Continue adding more petals around the central puddle, slightly overlapping each one to create a natural, layered effect, much like a real flower blooming.



Step 4: Build Layers and Finish the Flower. Spoon another, slightly smaller puddle of melted chocolate into the center of your first layer of petals. Add more petals in the same overlapping fashion, creating a second, inner layer. Now, incorporate the smaller petals you previously made into the very center of the flower to give it a realistic, tight bud appearance. Remember to keep a few of the larger petals on hand; these will be used to fill in any gaps around the finished flower once it’s placed on the cake. Set the assembled flower aside until the chocolate has completely hardened, which should take approximately 10 minutes.


Part 2: Creating the Elegant Marbled Chocolate Wrap
Now, let’s move on to the show-stopping marbled chocolate wrap that will encase your cake in a beautiful, artistic finish.
Step 5: Prepare Your Acetate Sheet. To create a perfect chocolate wrap, you’ll need a piece of acetate that is precisely the same height as your cake and a few inches longer than its circumference. For a standard 6-inch round cake, the circumference is a little under 19 inches, so aim for an acetate strip around 22-24 inches long. If your acetate sheets aren’t long enough, you may need to tape two pieces together securely with Scotch tape. Before proceeding, wrap the acetate sheet around your chilled cake to double-check that the size is correct. Place a piece of Scotch tape near the top of each end of the acetate sheet. Then, flip the sheet over so that the sticky side of the tape is facing up; this will help secure the wrap later.


Step 6: Melt the Chocolates for Marbling. Melt the three cups of white coating chocolate or regular white chocolate until smooth and fluid. For this specific technique, there’s no need to temper the regular chocolate; in fact, untempered chocolate will remain fluid for a longer period, making it easier to spread and significantly easier to cut through the finished cake without cracking. Melt the dark pink chocolate separately and keep it warm and nearby, along with the already melted light pink chocolate. Having all your melted chocolates ready ensures a smooth and continuous marbling process.

Step 7: Create the Marble Effect. In my book, I often demonstrate marbling directly on the acetate sheet, allowing for precise control. However, for this particular project, I’ve opted for a slightly different, equally effective approach: marbling the chocolate directly in the bowl first. Pour the melted dark pink and light pink chocolates into the bowl of melted white chocolate. Using a spatula, gently swirl the colors together. Be careful not to overmix; you want distinct ribbons of color, not a uniform blend. Once you’ve achieved your desired swirl, immediately pour the marbled chocolate onto the prepared acetate sheet. Using an offset spatula, swiftly and evenly spread the chocolate out to all the edges of the acetate, ensuring a consistent thickness across the entire surface.


Step 8: Wrap the Cake. Utilize the pieces of Scotch tape you placed earlier to help lift and handle the acetate sheet. Carefully wrap the chocolate-coated acetate around your chilled, crumb-coated cake. Begin at one end, gently pulling the sheet around the cake as you go, ensuring the chocolate side is facing the cake’s buttercream. Run your hand smoothly over the entire sheet to ensure that every part of the chocolate makes firm contact with the buttercream, creating a perfect bond. The end of the acetate sheet should overlap the beginning by a few inches. Do not press the overlap firmly onto the starting point of the sheet; simply ensure the chocolate is touching and let any excess hang freely off the side of the cake. This overlap will be trimmed later. Once the cake is fully wrapped, immediately pop it into the refrigerator. Allow the chocolate to harden completely, which usually takes about 15 minutes. Patience is key here! Removing the wrap too soon can result in a damaged or uneven chocolate finish, so resist the urge to peek early.


Part 3: Finishing Touches and Assembly
The final steps bring together your beautiful chocolate elements for a truly professional look.
Step 9: Remove the Acetate. Once the chocolate is completely set and firm, remove the cake from the refrigerator. Carefully and slowly peel off the acetate sheet. You’ll be left with a perfectly smooth, beautifully marbled chocolate wrap adhering to your cake.

Step 10: Trim the Chocolate Wrap. Using a sharp, small knife, gently score a precise line where the ends of the chocolate wrap overlap. Apply gentle, consistent pressure, running the tip of the knife cleanly up and down that line until it cuts through both layers of chocolate. Carefully remove the excess chocolate strip. If, by chance, you accidentally cause any breakage or a small piece comes off, don’t despair! You can easily reattach the broken piece of chocolate by applying a tiny bit of your leftover melted chocolate to secure it back in place. This trick works wonders for seamless repairs.


Step 11: Smooth the Seam. To achieve an invisible and flawless finish, spread a tiny amount of your extra melted chocolate over the trimmed seam. Immediately smooth it over with a clean fingertip or a small offset spatula. This blends the seam beautifully and makes it almost undetectable, giving your cake a truly professional edge.

Step 12: Place the Chocolate Flower. Carefully lift the hardened chocolate flower out of its foil cup by gently holding the edges of the foil. Slowly and carefully peel the aluminum foil away from the back of the chocolate flower. Once detached, position the exquisite chocolate flower on top of your cake. If needed, you can use a small dollop of buttercream or melted chocolate to secure it firmly in place. To complete the elegant presentation, fill in the top of the cake around the flower with the clear sanding sugar and white nonpareils, adding a sparkling, delicate touch. Don’t forget to tuck any remaining extra petals around the edges of the flower to fill in any small gaps and enhance its natural, full appearance.

Step 13: Final Touches and Serving. Your magnificent Marbled Chocolate Wrap Cake is now complete! For best results, store the cake at room temperature if serving within the day. If you plan to enjoy it later, the cake can be stored in the refrigerator for up to three days. When it’s time to slice and serve this beautiful creation, use a sharp knife that has been dipped in hot water and wiped clean. This technique ensures clean, precise cuts through the chocolate wrap, allowing each guest to enjoy a perfect slice. Remember to wipe the blade clean between each cut for the best presentation.
