Ingredients:
- 375g All purpose flour
- 300g Granulated sugar
- 1.5 tsp Baking powder
- 0.5 tsp Baking soda
- 225g Unsalted butter (cake)
- 240ml Buttermilk
- 3 Large eggs
- 2 Egg whites
- 2 tbsp Freeze dried strawberry powder
- 1 tsp Vanilla bean paste
- 2 drops Pink gel food coloring
- 450g Unsalted butter (frosting)
- 750g Confectioners' sugar
- 3 tbsp Heavy cream
- 1 tsp Clear vanilla extract
Instructions:
- Preheat and prep. Set your oven to 350°F (180°C) and grease your square and round pans.
- Whisk dry ingredients. Combine 375g flour, 300g sugar, strawberry powder, and leaveners in a stand mixer.
- Incorporate butter. Add 225g cubed butter and mix on low until the texture looks like wet sand.
- Whisk liquids. In a separate bowl, blend buttermilk, eggs, egg whites, vanilla paste, and pink gel.
- Combine slowly. Pour half the liquid into the flour mixture, beat for 1 minute, then add the rest.
- Bake the sponges. Divide batter between pans and bake for 35 minutes until a toothpick comes out clean.
- Cool completely. Let them rest in the pans for 10 minutes before moving to a wire rack.
- Cut the round. Slice the 8 inch round cake directly down the middle into two semi circles.
- Position the square. Place the square cake on your serving board like a diamond (one corner pointing at you).
- Attach the sides. Use a little frosting to glue the flat sides of the semi circles to the top two edges of the square.
- Crumb coat. Spread a thin layer of buttercream over the whole heart to lock in crumbs.
- Final frost. Apply the remaining buttercream and smooth with a bench scraper until the surface is velvety.
