Step 1: Prepare the Cupcake Batter

Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners. In a mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt. In another bowl, beat the butter and sugar until light and fluffy. Add the eggs one at a time, followed by the vanilla extract. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Stir in the red food coloring until the batter is evenly colored.

Step 2: Bake the Cupcakes

Divide the batter evenly among the cupcake liners, filling each about ¾ full. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Step 3: Make the Cream Cheese Frosting

In a mixing bowl, beat the cream cheese and butter until smooth. Gradually add the powdered sugar and vanilla extract, mixing until creamy and fluffy.

Step 4: Frost and Decorate

Once the cupcakes are completely cool, pipe or spread the cream cheese frosting on top. Garnish with red velvet crumbs or sprinkles if desired.
