Chocolate Vanilla Marble Cupcakes

Preheat oven to 350. Place cupcake liners in a 12-cup muffin tin, or spay a 9-inch cake pan.

In a small bowl, sift together flour, baking powder, baking soda, and salt.

In a second bowl, mix melted butter and oil together. Add in sugars and stir (mix will be gritty).

Stir in eggs, milk, vanilla, and yogurt and mix until blended.

Slowly, incorporate the dry ingredients into the wet ingredients, stirring gently.

Once the mix is just combined, transfer 1 cup of the batter into a new bowl.

Whisk in cocoa powder, coffee, and espresso powder.

Pour vanilla batter into muffin cups, about 1/4 way full.

Now, alternately spoon in chocolate and vanilla batter until each cup is 3/4 of the way full.

Take a tooth pick or cake tester to gently swirl the batters together.

Bake for 20-22 minutes or until a cake tester comes out clean.

Enjoy!
