• Step 1: Preheat your oven to 350°F (175°C). Grease and flour a 10-inch bundt pan, ensuring that every nook and cranny is coated to prevent sticking.
• Step 2: In a medium bowl, whisk together the all-purpose flour, baking soda, cinnamon, and salt. Set aside.
• Step 3: In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy, about 2-3 minutes. Beat in the eggs one at a time, scraping down the sides of the bowl as needed.
• Step 4: In a separate bowl, mash the ripe bananas until smooth. Stir in the sour cream and vanilla extract until well combined.
• Step 5: Gradually add the dry ingredients to the creamed butter mixture, mixing just until incorporated. Be careful not to overmix.
• Step 6: Gently fold in the mashed banana mixture until it’s evenly distributed throughout the batter.
• Step 7: Pour the batter into the prepared bundt pan, smoothing the top with a spatula.
• Step 8: Bake the Banana Bundt Cake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
