Preparation
- Preheat your oven to 350°F (175°C) and line a cupcake tin with festive liners.
- Cream together 1 cup of softened unsalted butter and 2 cups of granulated sugar until light and fluffy.
- Add 4 large eggs one at a time, mixing well after each addition, and blend in 1 cup of sour cream and 1 cup of buttermilk.
- In a separate bowl, whisk together 3 cups of all-purpose flour, 1 tablespoon of baking powder, 1 teaspoon of salt, and 1/2 cup of cocoa powder.
- Gradually add dry mixture to the wet batter and mix on low speed until just combined.
- Divide the batter into three bowls; leave one plain, mix the second with cocoa for dark red, and color the third with red and blue food coloring.
- Alternately drop spoonfuls of each colored batter into the cupcake liners, creating a marbled effect.
- Bake for 18-20 minutes until a toothpick comes out clean.
- Cool for 5 minutes in the tin, then transfer to a wire rack to cool completely before frosting.
- Frost with a generous swirl of vanilla buttercream.

Notes
Ensure butter is at room temperature for the best texture and avoid overmixing the batter.
