In a small bowl, mix mashed bananas with the lemon juice; set aside.

Step 3

In a medium bowl, mix flour, baking soda and salt; set aside.

Step 4

In a large bowl with an electric mixer, cream 3/4 cup butter and 2 cups sugar until light and fluffy; about 3 minutes. Beat in eggs, one at a time, then stir in 2 teaspoons of vanilla.

Step 5

Beat in the flour mixture alternately with the buttermilk until just combined. Stir in mashed bananas.

Step 6

Pour batter into prepared pan and bake in preheated oven for 60-75 minutes, or until toothpick inserted in center comes out clean. This could take longer than 75 minutes depending on your oven.
