Ingredients:
- 325g cake flour
- 300g granulated sugar
- 225g unsalted butter, softened
- 240ml whole milk
- 4 large egg whites
- 1 tbsp vanilla bean paste
- 1.5 tsp baking powder
- 0.5 tsp salt
- 2 drops soft pink gel food coloring
- 450g unsalted butter (for buttercream)
- 900g confectioners' sugar
- 2 tbsp heavy cream
- 1 tsp clear vanilla extract
- 2 drops dusty rose gel coloring
- 1 roll 1/2-inch pink satin ribbon
- 1 tsp edible pink glitter
Instructions:
- Prep the pans. Grease your 9 inch heart pan and line the bottom with parchment paper.
- Sift dry ingredients. Combine 325g cake flour, 1.5 tsp baking powder, and 0.5 tsp salt into a large bowl.
- Cream butter and sugar. Beat 225g butter and 300g sugar until it looks pale and fluffy. This should take at least 5 minutes.
- Incorporate liquids. Slowly add the egg whites, milk, and 1 tbsp vanilla bean paste, mixing on low.
- Add the tint. Fold in 2 drops of soft pink gel coloring until the batter is a uniform, delicate rose.
- Bake the sponge. Pour into the pan and bake at 350°F for 35 minutes until a toothpick comes out clean and the edges pull away.
- Cool completely. Let the cake rest in the pan for 10 minutes, then flip onto a wire rack to cool for 2 hours.
- Whip the frosting. Beat 450g butter with 900g sugar and 2 tbsp cream until it's velvety and stiff.
- Apply crumb coat. Spread a thin layer of buttercream over the heart to trap crumbs, then chill for 20 minutes.
- Final frost and ribbon. Apply the dusty rose frosting, smooth the sides, and gently press the pink satin ribbon around the base. Top with edible glitter for a shimmer finish.
