Instructions:
- Preheat your oven to 350°F (175°C). Grease and flour two 8 inch pans. Note: This prevents the delicate velvet crumb from sticking to the edges.
- Sift together 315g all purpose flour, 1 tsp baking soda, 1 tsp salt, and 2 tbsp cocoa powder. Note: Sifting aerates the dry mix for a fluffier result.
- Cream 115g softened butter and 300g granulated sugar in your mixer for 5 minutes until pale and fluffy.
- Add 2 large eggs one at a time, beating well after each. until the mixture looks like smooth buttercream.
- Whisk 240ml buttermilk, 120g Greek yogurt, 1 tbsp vinegar, 1 tsp vanilla, and 2 tbsp red food coloring in a separate jug.
- Alternate adding the dry ingredients and the buttermilk mixture to the butter, starting and ending with dry.
- Fold the batter gently by hand with a spatula for the last few turns. until no red streaks or white flour pockets remain.
- Divide the batter evenly between the pans. Bake for 35 minutes until a toothpick comes out with just a few moist crumbs.
- Cool in the pans for 10 minutes, then invert onto a wire rack to cool completely.
- Whip 225g chilled cream cheese and 4 tbsp butter with 240g powdered sugar and vanilla until velvety and hold stiff peaks.
