Preheat your oven to 350°F (175°C) and line your cupcake pan with festive Valentine’s Day cupcake liners.

Combine the cake mix, whole milk, unsalted sweet cream butter, and large eggs in a large mixing bowl. Mix until smooth.

Fill each liner 3/4 full with the batter and bake for 21 minutes or until a toothpick comes out clean.

Cool the cupcakes completely on a wire rack before frosting.

Beat together the frosting ingredients until you achieve a smooth and creamy consistency.

Pipe the frosting onto the cooled cupcakes, creating a generous swirl.

Decorate each cupcake using Reese’s cups for heads, Ghirardelli wafers for ears, small edible eyes, brown M&M’s for noses, and heart sprinkles.
