Equipment
You will need a few basic kitchen tools for this recipe.
- Large baking sheet
- Parchment paper
- Aluminum foil
- Hand mixer or whisk
- Mixing bowls
- 5-inch round cutter (optional)

Instructions
Follow these simple steps to create your beautiful mosaic Galentines cake and optional truffles.
For the Mosaic Cake
- Prep Oven & Pan: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper.
- Create Dividers: Measure and cut a 15-by-15-inch piece of aluminum foil. Fold it in half, then continue folding the folded edge into roughly 2-by-15-inch strips until you are about 4 inches from the bottom. Fold out the unfolded pieces to create a sturdy divider. Place the foil divider on the parchment-lined sheet tray, ensuring it is straight and the edges are flattened to prevent batter from spilling. Place strips equal distance apart, roughly 6 inches, to create three 6-by-12 inch rectangles. Spray the pan with nonstick spray and set it aside.
- Prepare Batter: Prepare the cake mix according to the box instructions. Replace the water with whole milk and the oil with melted unsalted butter. Add the instant pudding mix. Use a hand mixer or whisk to stir the batter for about 2 minutes on medium speed until smooth.
- Divide & Tint: Pour one-third of the vanilla batter into one of the empty rectangles in your prepared pan. Tint half of the remaining batter pink with food coloring and pour it into the second empty rectangle. Add red food coloring to the last portion of pink batter, mix until combined, and pour it into the final open rectangle.
- Bake: Bake for about 22 to 26 minutes, or until a toothpick inserted into the center of each cake comes out clean.
- Cool: Remove the cake from the oven and let it cool completely on the baking sheet.
To Decorate and Assemble
- Remove & Cut: Carefully remove the three distinct cake sections from the pan and gently peel away the foil dividers. Stack the cakes into a large rectangle, or use a 5-inch round cutter to cut two circles from each colored cake. If using circles, cut them in half again. Mix and match the colored halves to reassemble them into new, two-toned rounds, creating your mosaic effect.
- Stack Layers: As you stack your cake rounds, brush each layer with a thin, even coating of simple syrup. Pipe a layer of your chosen frosting between each cake layer for both flavor and stability.
- Frost Cake: Once stacked, apply a thin layer of vanilla or strawberry frosting as a crumb coat over the entire cake. Chill for 15 minutes, then apply a final, smooth layer of your desired frosting evenly over the entire Galentines cake.
- Add Sprinkles: Decorate generously with pink, red, and white sprinkles while the frosting is still soft.
For the Cake Truffles (Optional)
- Make Crumble: Combine any remaining cake scraps with just enough frosting so the mixture holds its shape when pressed together.
- Mold Truffles: Pour a thin layer of melted dark chocolate into a silicone truffle mold, ensuring the bottom and sides are fully coated. Let the chocolate harden completely. Press a small amount of the cake mixture firmly into each mold.
- Finish Truffles: Top the cake mixture with additional melted chocolate, smoothing the surface. Let the truffles harden completely in the refrigerator.
- Garnish: Carefully remove the cake truffles from the silicone mold. Decorate them further with extra melted chocolate drizzles and festive sprinkles.
Pro Tips & Troubleshooting
These expert tips will help ensure your Galentines cake is perfect.
- Achieve Moist Cake: Do not overbake your cake, as this leads to dryness. Brushing simple syrup on cooled layers adds essential moisture.
- Vibrant Colors: Always opt for gel food coloring over liquid for significantly more intense and professional-looking hues. Understanding the differences between various food coloring types can dramatically enhance your baking results.
- Prevent Cracks: Ensure your cake layers are completely cooled before attempting to stack or decorate them. Warm cake is fragile.
- Smooth Frosting: Apply a thin crumb coat first, chilling it until firm, then apply a final, thicker layer for a perfectly smooth finish.
- Room Temperature Ingredients: Use room temperature milk and butter for a consistent, smooth batter that bakes evenly.
- Overmixing: Avoid overmixing the cake batter, which can develop gluten and result in a tough, dense cake.
- Cake Bleeding: If colors are very wet, chill each cake layer before assembling to prevent colors from bleeding into one another.

Make the most of your mosaic sheet cake with these tips.
- Serving Suggestions: Arrange slices of the mosaic cake on a festive platter. Serve the optional cake truffles alongside for an extra special treat.
