Instructions
Preparation
- Preheat your oven to 350°F (175°C). Prepare a 9-inch round cake pan by greasing or lining it with parchment paper.
- In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until fluffy.
- In a separate bowl, mix the mashed bananas, sour cream (or Greek yogurt), vegetable oil, egg, and vanilla extract until smooth.
- Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
- Gently fold in the blueberries until evenly distributed.
- Pour the batter into the prepared cake pan, smoothing the top with a spatula.
Crumb Topping Preparation
- In a small bowl, combine the flour, brown sugar, cubed butter, and cinnamon. Mix until it resembles coarse crumbs.
- Sprinkle the crumb topping evenly over the batter in the cake pan.
Baking
- Bake in the preheated oven for 30 to 35 minutes or until a toothpick inserted comes out clean.
- Allow the cake to cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
Serving
- Serve warm or at room temperature and enjoy!
Notes
Use very ripe bananas for best flavor; consider adding nuts to the crumb for extra crunch; toss blueberries in flour before folding to prevent sinking.
