Chocolate Chocolate Chip Muffins

I made these for an after school snack. They were yummy. I didn't say they were good for you.

1 3/4 cups all-purpose flour

2 teaspoons baking powder

1/2 teaspoon baking soda

2 tablespoons cocoa powder

3/4 cup sugar

3/4 cup semisweet chocolate chips

1 cup milk

1/3 cup plus 2 teaspoons vegetable oil

1 egg

1 teaspoon pure vanilla extract

Preheat the oven to 400 degrees F. Put the flour, baking powder, baking soda, cocoa, sugar, and chocolate chips into a large bowl. Pour all the liquid ingredients into a measuring jug. Mix the dry and wet ingredients together. Bake for 20 minutes.
