Step 1

Preheat the oven to 375 degrees F. Coat two 6-inch metal round baking pans with nonstick spray (or you can use one 9-inch round pan). Trace the pans onto parchment paper and cut the rounds out. Trim as needed to fit and place inside of each pan. Set aside.

Step 2

In a large bowl, stir together the yogurt, banana, butter, eggs, and vanilla.

Step 3

Add the flour, baking powder, baking soda, and salt.

Step 4

Gently stir the yogurt mixture into the flour mixture.

Step 5

Pour half of the batter into each of the prepared pans. You will use about 1½ cups batter in each pan.

Step 6

Bake for 16-20 minutes, or until the edges are lightly golden brown and a cake tester inserted into the center comes out cleanly. Let cool for 2 minutes in the pan, then carefully invert onto wire racks. Remove the parchment paper rounds and cool completely.

Step 7

Top with desired frosting.
