Two-Layer Banana Cake
Makes 2 9-inch layers. Use this for Options 2 or 3 below.
3 1/2 cups (14 3/8 ounces or 406 grams) cake flour
2 teaspoons (10 grams) baking powder
1 1/2 teaspoons (8 grams) baking soda
3/4 teaspoon (5 grams) salt
3/4 teaspoon (2 grams) cinnamon
1 cup (2 sticks, 8 ounces or 227 grams) unsalted butter, room temperature
1 cup (7 ounces or 200 grams) sugar
1 cup (7 5/8 ounces or 218 grams) packed golden brown sugar
4 large eggs
2 cups mashed or pureed very ripe bananas (5 to 6 large)
6 tablespoons (3 1/4 ounces or 91 grams) sour cream or (weight will vary) plain yogurt
2 teaspoons (10 ml) vanilla extract
Preheat oven to 350°F. Line the bottoms of 2 9-inch round cake pans with parchment paper, then coat the paper and sides of pans with butter and flour, or a nonstick spray. [If you’re using Option 2 below, you’ll also want to butter and flour 3 muffin cups or ramekins.]
Whisk cake flour, baking powder, baking soda, salt and cinnamon in a medium bowl and set aside. Using electric mixer, beat butter and both sugars in large bowl until blended. Beat in eggs one at a time, then bananas, sour cream, and vanilla. Beat in dry ingredients in two additions just until combined. Divide batter among two pans; you’ll want approximately 5 cups of batter per pan. [If you’re using Option 2 below, fill your 3 muffin cups or ramekins two-thirds of the way up with batter and divide remaining batter among your 2 9-inch pans.]
Bake cake until tester inserted into center of each layer comes out clean, about 40 to 45 minutes. [Muffin cups should bake for approximately 15 to 20 minutes. Please watch them carefully.] Cool each layer in its pan for 15 minutes before flipping out onto a rack to cool the rest of the way.
