Moist Banana Nut Bread with Streusel Topping
Step-by-Step Instructions
- Preheat & prep — Set oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line with parchment paper (leave overhang for easy lifting).
- Cream the base — In a large bowl, beat softened butter and sugar until light and fluffy (2–3 minutes).
- Add wet ingredients — Mix in eggs one at a time, then stir in mashed bananas, sour cream, and vanilla until smooth.
- Mix dry ingredients — In a separate bowl, whisk flour, baking soda, salt, and cinnamon.
- Combine — Gently fold dry ingredients into wet until just combined (a few lumps are fine — overmixing = tough bread). Fold in nuts or chips if using.
- Make the magic topping — In a small bowl, combine flour, brown sugar, and cinnamon. Cut in cold butter with a pastry cutter or your fingers until crumbly. Stir in chopped nuts.
- Assemble — Pour batter into the pan. Sprinkle streusel generously over the top and gently press it in so it sticks.
- Bake — Bake 55–65 minutes until a toothpick in the center comes out clean (a few moist crumbs are perfect). If the top browns too fast after 45 minutes, loosely cover with foil.
- Cool — Let cool in the pan 10 minutes, then lift out and cool completely on a wire rack.
