Instructions
Prepare for Baking: Preheat your oven to 350°F (175°C). Grease and line a 9x9 inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, instant banana pudding mix, baking powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a large bowl, using an electric mixer, cream the softened butter and granulated sugar together on medium-high speed until light and fluffy, about 2-3 minutes.
Add Wet Ingredients: Beat in the eggs one at a time, followed by the mashed banana, sour cream (or yogurt), and vanilla extract. Mix until well combined, scraping down the sides of the bowl as needed.
Combine Wet and Dry: With the mixer on low, add the dry ingredients in three parts, alternating with the buttermilk in two parts, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.
Fold in Wafers: Gently fold in the 1/2 cup of chopped vanilla wafers.
Bake: Pour the batter into the prepared pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Cool Completely: Let the cake cool in the pan for 15 minutes, then use the parchment paper to lift it out onto a wire rack to cool completely before frosting.
Make the Chocolate Frosting: While the cake cools, melt the 1/2 cup of butter for the frosting in a saucepan over medium heat. Whisk in the cocoa powder and milk (or cream) until smooth. Bring the mixture just to a boil, then immediately remove from heat.
Finish the Frosting: Transfer the hot cocoa mixture to a mixing bowl. Gradually beat in the sifted powdered sugar, vanilla extract, and salt until the frosting is smooth and spreadable. It will thicken as it cools slightly.
Frost and Garnish: Spread the chocolate frosting evenly over the completely cooled cake. Garnish with additional crushed vanilla wafers. Slice and serve.
Notes
🔹 Using room temperature ingredients is key for a smooth, well-combined batter.🔹 The riper the bananas, the more flavor and sweetness they will impart.🔹 Do not prepare the pudding according to package directions; you are using the dry powder mix directly in the dry ingredients.🔹 For an extra banana punch, you can add 1/2 cup of diced bananas to the batter along with the mashed.🔹 Store leftover cake in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 4 days.
