Looking to surprise your friends with a fun and cheeky dessert? Making a butt cake is a playful way to add humor and creativity to any celebration. It’s easier than you might think and perfect for birthdays, bachelorette parties, or just a lighthearted treat.

You don’t need to be a professional baker to create this eye-catching cake. With a few simple ingredients and some basic decorating tips, you can craft a cake that’s both delicious and hilarious. Whether you want a realistic look or a cartoonish style, this guide will walk you through the steps to make your own butt cake with confidence.

How to Make a Butt Cake: Step-by-Step Guide

1. Prepare the Batter: Mix your preferred cake batter, such as vanilla or chocolate, following the recipe’s instructions. Use two round cake pans, 8 or 9 inches in diameter, for ideal shaping.
2. Bake the Cakes: Pour batter evenly into the pans. Bake at 350°F (175°C) for 25-30 minutes or until a toothpick comes out clean. Cool cakes completely before shaping.
3. Shape the Cake: Trim one cake into two equal halves. Position the halves with rounded sides facing each other on a serving board. Place the second cake behind the halves, rounding top edges to form the lower back.
4. Apply a Crumb Coat: Spread a thin layer of buttercream frosting over the entire cake to seal crumbs. Chill for 20 minutes to set.
5. Decorate the Cake: Use flesh-toned fondant or buttercream for the skin. Smooth the frosting evenly to mimic natural contours. Add shading with edible food coloring or powdered cocoa for depth.
6. Add Details: Use small piping tips to outline cheeks or create dimples. Shape fondant or use chocolate candies for realistic effects, such as creases or a thong design.
7. Final Touches: Refrigerate the cake to firm the frosting. Bring to room temperature before serving to enhance flavor and texture.

Ingredients and Tools You’ll Need

Gathering the right ingredients and tools simplifies making a butt cake and ensures precise shaping and decorating. Focus on flavors, fillings, and equipment designed for sculpted cakes.

Choosing the Right Cake Flavor and Fillings

Select moist cake flavors like vanilla, chocolate, or red velvet for easy carving and rich taste. Choose fillings that complement the cake, such as buttercream, cream cheese frosting, or fruit preserves like raspberry or strawberry. Use firm fillings to maintain the cake’s structure during shaping.

Essential Baking Tools for Shaping the Cake

Use two 8 or 9-inch round cake pans for creating the butt shape. Have a serrated knife or cake leveler to trim and sculpt the cake layers accurately. Employ an offset spatula for applying smooth crumb coats and frosting. Use cake boards for support and stability when stacking. Finally, keep piping bags and small fondant modeling tools ready for adding detailed decorations like dimples and creases.

Baking and Preparing the Cake Layers

Start by focusing on baking moist, even layers that form a solid base for your butt cake. Proper preparation and handling ensure a smooth shaping process and a sturdy final design.

Tips for Baking Moist and Even Cake Layers

Use cake mixes or recipes that emphasize moisture, such as those with oil or buttermilk. Avoid overmixing the batter since it creates dense layers. Distribute batter evenly between two 8- or 9-inch round pans. Tap the pans gently on the counter to release air bubbles. Bake at 350°F (175°C) for 25 to 30 minutes, checking doneness with a toothpick. Rotate pans halfway through baking to prevent uneven cooking.

Cooling and Trimming the Cake for Shaping

Cool cakes in the pans for 10 minutes, then transfer them to wire racks to cool completely. Cooling prevents crumbly layers during trimming. Use a serrated knife or cake leveler to slice each cake horizontally if needed for more layers. Trim one cake horizontally and split the top layer into two halves. Place the halves side by side on a cake board to create the rounded shape of buttocks. Use the other cake as the base or for additional height, depending on your design. Apply slight trimming to refine the curves and edges before frosting.

Sculpting the Butt Shape

Sculpting the butt shape requires careful carving and strategic assembly to achieve smooth curves and stability. Use precise techniques for shaping and layering to create a polished final design.

Carving Techniques for a Smooth Contour

Start by using a serrated knife or cake leveler to trim the cake halves into rounded forms that mimic natural curves. Carve gradually, removing small amounts of cake at a time to avoid overcutting. Smooth edges with gentle, sweeping strokes to ensure even contours. Use an offset spatula or your fingers to refine curves, blending any sharp lines. If needed, add small cake scraps and press them onto uneven areas, then cover with a crumb coat to unify the surface before final frosting.

Assembling the Layers for Stability

Stack the cake layers with a firm filling like buttercream or ganache to bind them securely. Apply a thin layer of frosting between layers to act as adhesive without adding bulk. Position the two rounded halves side by side, pressing gently to form the buttocks shape. Chill the cake between steps to keep the structure firm. Use cake boards or dowels underneath if the cake weighs heavily, ensuring balance and support during handling and decorating.

Decorating Your Butt Cake

Decorating your butt cake transforms the sculpted shape into an eye-catching, playful dessert. Focus on layering frosting smoothly and adding realistic touches for the best results.

Applying Crumb Coat and Final Frosting

Apply a thin crumb coat of buttercream frosting using an offset spatula to seal crumbs and create a smooth base. Chill the cake for at least 30 minutes to firm this layer. Next, spread a thicker, even layer of frosting over the chilled crumb coat. Work swiftly to avoid melting, smoothing the surface with long, gentle strokes. Use a bench scraper or spatula to perfect edges and curves, maintaining the butt shape. Refrigerate again to set the final frosting layer before adding more decorations.

Using Fondant and Edible Colors for Realistic Details

Roll out flesh-toned fondant evenly to cover the cake if you prefer a polished, smooth surface. Drape the fondant carefully over the cake, smoothing out air bubbles with a fondant smoother. Trim excess fondant at the base, and sculpt subtle indentations to mimic natural skin creases. Use edible airbrush colors or dust powders in shades of pink, brown, and peach to add depth and shading around curves and dimples. Pipe buttercream lines or use small fondant pieces to accentuate details like the gluteal crease, emphasizing realism and texture.

Presentation and Serving Tips

Display your butt cake on a sturdy cake board or platter to support its shape. Use a non-slip mat underneath to prevent sliding during transport or serving. Arrange complementary decorations around the cake, such as edible flowers, sprinkles, or themed toppers, to enhance its visual appeal without overpowering the main design.

Slice the cake with a sharp serrated knife to maintain clean edges and preserve the carving detail. Serve at room temperature to maximize flavor and texture; remove the cake from the refrigerator 30 to 60 minutes before cutting. Provide small plates and forks, encouraging guests to appreciate both the novelty and taste of the cake.

If storing leftovers, cover the cake loosely with plastic wrap to prevent drying while preserving decoration integrity. Refrigerate within two hours of serving and consume within 2 to 3 days to ensure freshness. Rechill chilled buttercream-frosted cakes before serving again, allowing them to soften at room temperature as before.
