Ingredients

Ingredients List:
- 3 and 1/4 cups all-purpose flour (Make sure to sift for a lighter cake)
- 2 teaspoons baking soda
- 1/2 teaspoon salt
- 8 ounces unsalted butter, room temperature (Brands like Kerrygold work wonders)
- 1 and 3/4 cups granulated sugar
- 2 and 1/4 teaspoons pure vanilla extract (Nielsen-Massey is my go-to)
- 2 large eggs (preferably organic or free-range)
- 2 cups very ripe bananas, mashed (the riper, the better!)
- 1 cup full-fat sour cream (adds a rich creaminess)
- 1/2 teaspoon ground cinnamon (optional, but I say it enhances the flavors)
- For the glaze:
- 2.5 ounces unsalted butter
- 1/2 cup brown sugar
- 2 tablespoons milk (whole or 2%)
- 1/4 teaspoon vanilla extract
- 3/4 cup powdered sugar, sifted
- 1/4 cup walnuts, toasted and chopped (for those irresistible crunchy toppings)
Notes:
- Use the ripest bananas for optimal sweetness.
- Set your butter and eggs out ahead of time so they’re at room temperature for the creaming process.
Step-by-Step Instructions
- Preheat the Oven: Preheat the oven to 350°F (175°C). Start this early so that your oven is ready for a perfectly baked cake.
- Mash Your Bananas: In a bowl, mash the ripe bananas until mostly smooth. I’m talking about a lovely, mushy texture here!
- Mix Dry Ingredients: In another bowl, whisk together 3 and 1/4 cups flour, 2 teaspoons baking soda, 1/2 teaspoon salt, and 1/2 teaspoon ground cinnamon. Set this aside.
- Cream Butter and Sugar: In a large mixing bowl, beat the 8 ounces of butter and 1 and 3/4 cups of sugar until light and fluffy—about 3-5 minutes. You want to see a pale color and feel that airy texture.
- Incorporate Eggs: Add 2 and 1/4 teaspoons of vanilla extract, followed by the eggs, one at a time, mixing well after each addition. This helps to create a stable emulsion.
- Add Bananas and Alternate: Incorporate the mashed bananas, mixing just until combined. Next, fold in your dry mixture alternately with 1 cup of sour cream, starting and ending with the dry mix. This method keeps the cake light and fluffy.
- Prepare the Pan: Grease a Bundt pan or line with parchment paper to prevent sticking. Pour the batter into the prepared pan, smoothing out the top.
- Bake: Bake for 55 to 65 minutes until a toothpick comes out with moist crumbs—don’t worry about a few moist crumbs, you want it to be moist!
- Cool: Let the cake cool in the pan for 15 to 20 minutes, then invert it onto a wire rack to cool completely.
- Glaze it Up: For the glaze, combine 2.5 ounces of butter, 1/2 cup of brown sugar, and 2 tablespoons of milk in a saucepan. Melt over medium heat, stirring constantly. Remove from heat, then stir in 1/4 teaspoon of vanilla extract and 3/4 cup of powdered sugar until smooth.
- Finish with Walnuts: Drizzle the glaze over the cooled cake and sprinkle with 1/4 cup of toasted walnuts before serving.
Chef’s Tips:
- Place a baking sheet below your cake pan during baking to catch any potential drips.
- Ensure your bananas are SUPER ripe; the dark spots show they’re packed with flavor!
