This marble cupcake recipe is perfect for those who want a smaller portion size. It's a classic vanilla and chocolate cupcake swirled together to create a beautiful marble effect. To make the cupcakes, start by creaming butter and sugar together until light and fluffy. Then add eggs, one at a time, followed by vanilla extract. In a separate bowl, whisk together flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with milk. Finally, divide the batter in half and mix cocoa powder into one half. Fill cupcake liners halfway with the vanilla batter, then add a spoonful of chocolate batter on top. Use a toothpick to swirl the batter together to create a marble effect. Bake for 18-20 minutes at 350°F. Let the cupcakes cool before frosting them with your favorite frosting.
