Ingredients
 

Main Ingredients

  • 2.25 cup finely crushed vanilla wafer crumbs
  • 1.25 cup all-purpose flour
  • 1.25 tsp baking powder
  • 0.5 tsp baking soda
  • 0.5 tsp fine salt
  • 0.5 tsp ground cinnamon
  • 0.5 cup unsalted butter, softened
  • 0.75 cup granulated sugar
  • 0.25 cup light brown sugar, packed
  • 3.5 fl oz beaten eggs about 2 large eggs
  • 1.5 cup mashed ripe bananas
  • 0.5 cup sour cream
  • 0.25 cup whole milk
  • 1.5 tsp vanilla extract
  • 0.5 cup chopped walnuts optional
  • 0.5 cup coarsely crushed vanilla wafers optional, for topping

Instructions

Preparation Steps

  • Heat oven to 350°F. Grease a 9×5-inch loaf pan and line with a parchment sling.
  • Crush wafers into fine crumbs. Whisk crumbs with flour, baking powder, baking soda, salt, and cinnamon.
  • Cream softened butter with granulated and brown sugars until light and fluffy, about 2–3 minutes.
  • Beat in the beaten eggs gradually, then mix in vanilla until smooth.
  • Stir in mashed bananas and sour cream until evenly combined.
  • Add dry mixture in two additions, alternating with the milk. Mix just until no dry spots remain.
  • Fold in walnuts, if using. Spread batter into the prepared pan and smooth the top.
  • Sprinkle the top with extra crushed wafers, if desired. Bake 50–60 minutes, until a tester comes out clean.
  • Cool in the pan 15 minutes. Lift out and cool completely on a rack before slicing.

Notes

Try a maple glaze: whisk 1/2 cup powdered sugar with 1–2 tbsp maple syrup and drizzle over the cooled cake. Swap walnuts for pecans, or fold in mini chocolate chips. Store airtight at room temperature for 2–3 days or freeze sliced portions up to 2 months.
