Ingredients
Banana Bread
- 3–4 medium ripe bananas, mashed
- ½ cup softened butter
- 1 cup granulated sugar
- 2 Tbsp brown sugar
- 2 eggs
- 1½ tsp vanilla extract
- ¾ tsp cinnamon
- 2 cups all-purpose flour
- 1 tsp baking soda
- ¼ tsp salt
- 2 Tbsp sour cream or Greek yogurt
Crumb Topping
- 1 cup flour
- 1 cup brown sugar
- 1 tsp cinnamon
- 6 Tbsp cold unsalted butter, cut into pieces
Instructions
Step 1: Preheat & Prep
Preheat oven to 350 °F (175 °C). Grease two 8×4″ loaf pans or line with parchment paper
Step 2: Make the Batter
Cream butter, granulated sugar, and brown sugar until light. Add eggs one at a time, then vanilla. Stir in mashed bananas and sour cream. In a separate bowl, whisk flour, baking soda, salt, and cinnamon then fold into wet ingredients until just combined
Step 3: Prepare the Crumb Topping
Combine flour, brown sugar, and cinnamon. Cut in cold butter with a pastry cutter until mixture resembles coarse crumbs
Step 4: Assemble & Bake
Transfer batter into prepared pans, smoothing the surface. Generously sprinkle the crumb topping over the batter. Bake for 35–40 minutes, or until a toothpick inserted into the center yields a few moist crumbs
Step 5: Cool & Serve
Allow loaves to cool in pans for 10 minutes, then transfer to a wire rack to cool completely before slicing
Tips & Notes
- Use very ripe bananas for maximum sweetness and moisture.
- A thick crumb topping is encouraged—this recipe is not stingy on Streusel!
- If the tops brown too quickly before the centers are done, tent with foil during baking
Storage
- Store at room temperature in an airtight container for up to 3 days.
- Freeze slices tightly wrapped for up to 3 months—perfect for later cravings.
