Step 1: Prepare the Cake Pans
Preheat the oven to 350°F. Grease and line three 6-inch or three 8-inch round cake pans with parchment paper.
Step 2: Mix the Dry Ingredients
If using the homemade flour blend, whisk together the sweet rice flour, white rice flour, tapioca flour, brown rice flour, xanthan gum, baking powder, baking soda, and salt until completely combined.
For the all-purpose or Measure for Measure versions, whisk together the flour, baking powder if needed, salt, and xanthan gum only if your flour blend does not already contain it.
Step 3: Cream the Butter and Sugar
Using a stand mixer or hand mixer, beat the butter and sugar until light, fluffy, and pale in color, about 4 to 5 minutes.
Step 4: Add the Eggs and Vanilla
Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 5: Finish the Batter
Alternate adding the dry ingredients with the milk. Mix only until combined. Fold in the sour cream if using the homemade flour blend.
The batter should be smooth and creamy.
Step 6: Bake the Cakes
Divide the batter evenly between the prepared pans.
Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes before transferring them to cooling racks. Cool completely before decorating.
Step 7: Make the Buttercream
Beat the butter until creamy and smooth.
Gradually add the powdered sugar while mixing on low speed.
Add the vanilla, salt, and enough heavy cream to create a smooth, spreadable frosting.
Tint most of the buttercream royal blue. Leave a small amount a lighter blue if desired to create texture.
Step 8: Create the Surprise Center
Level each cake layer.
Using a round cookie cutter, cut a hole from the center of the middle two cake layers.
Leave the bottom and top layers whole.
Step 9: Assemble the Cake
Place one whole cake layer on the cake stand.
Spread with buttercream.
Add one hollow layer.
Spread with buttercream.
Add the second hollow layer.
Fill the cavity with gluten-free candies, sprinkles, chocolate pearls, or your favorite surprise filling.
Place the final whole cake layer on top.
Step 10: Apply the Crumb Coat
Spread a thin layer of buttercream over the entire cake.
Refrigerate for 20 to 30 minutes until firm.
Step 11: Decorate the Cake
Apply a thick layer of royal blue buttercream using an offset spatula.
Create textured strokes all around the cake for an artistic finish.
Press small pieces of edible gold foil or edible gold leaf randomly across the buttercream to create the dramatic abstract appearance shown in the photo.
Dust lightly with edible gold luster dust if desired.
Finish by covering the cake board with gold sanding sugar for an elegant presentation.
Step 12: Chill and Serve
Refrigerate the cake for 30 minutes before slicing.
When cut, the colorful surprise center will spill onto each plate for a beautiful celebration moment.
For the cleanest slices, chill the cake before serving and wipe the knife clean between cuts.
Only use edible gold foil or edible gold leaf specifically labeled for food use.
Gel food coloring creates vibrant color without thinning the buttercream.
The cake layers may be baked one day in advance and wrapped tightly before decorating.
Buttercream can be prepared two days ahead and refrigerated. Bring it back to room temperature and whip again before using.
Store the finished cake covered in the refrigerator for up to 4 days.
Bring the cake to room temperature for about 30 minutes before serving for the best flavor and texture.
The surprise center works well with gluten-free chocolate candies, mini cookies, chocolate pearls, colorful sprinkles, or wrapped messages for special celebrations.
