Step 1

Preheat the oven to 350° F. Grease and flour a 9x5-inch loaf pan.

Step 2

Whisk the flour, baking powder, and salt in a medium-sized bowl and set it aside.

Step 3

With a stand mixer, beat the butter and sugars on high speed until light and fluffy, about 3-4 minutes.

Step 4

Turn the speed to medium, and add the vanilla and eggs one at a time. Add the mashed bananas and milk, and mix until combined.

Step 5

Add the dry ingredients and mix just until incorporated.

Step 6

Pour the cake batter into the prepared loaf pan and bake for 50-55 minutes, until the top is golden and a toothpick comes out clean when inserted into the center.

Step 7

Cool the cake in the pan for 5-10 minutes before carefully removing it and transferring it to a wire rack to finish cooling.
