Step-by-Step Instructions

Trim the Cake Layers
Place the first cooled cake layer on a cutting board. Using a serrated knife, make two angled cuts at the bottom of the cake to create the pointed base of the heart. These cuts should meet at the center bottom. Repeat this process with the second cake layer, using the first trimmed layer as a guide if helpful.
Prepare the Cardboard Base
Trim the 8-inch cardboard circle using the same cuts made to the cake layers. This creates a heart-shaped base that supports the cake and makes transferring it after decorating much easier.
Create the Heart Shape
Place the trimmed cardboard base on the turntable and spread a small amount of buttercream on top. Position the first cake layer onto the base. Take the two curved pieces trimmed earlier and place them at the top of the cake to form the rounded heart shape. Use buttercream to secure them firmly.
Fill and Stack
Spread an even layer of buttercream over the first cake layer. Place the second cake layer on top, aligning it carefully. Attach the curved pieces again with buttercream to complete the heart shape.
Crumb Coat the Cake
Apply a thin layer of buttercream over the entire cake, focusing on defining the heart shape and sealing in crumbs. Smooth gently with an icing smoother and angled spatula. Refrigerate for at least 30 minutes until the crumb coat is firm.
Final Frosting
Frost the cake with a smooth layer of buttercream. If using colored frosting, tint the buttercream with AmeriColor Soft Pink for a soft base. Use the icing smoother to level the sides, then pull excess frosting inward at the top edge with a small angled spatula to create clean lines. Chill for 20 minutes.
Decorate
Divide remaining buttercream into three bowls. Tint one deep red using Chili Pepper and Super Red, another mid-toned pink, and the last a pale pink. Use Wilton Tip 1M to pipe rosettes, Tip 4B for stars, and Tip 32 for smaller swirls. Finish with Sprinkle Pop Vintage Rose Gold sprinkles if desired.
