Ingredients You’ll Need

Here’s everything you’ll need to create this flavor-packed banana bread:

113g (½ cup) unsalted butter
190g (1½ cups) all-purpose flour
150g (¾ cup) granulated sugar
1 tsp ground cinnamon
¼ tsp ground nutmeg
½ tsp baking soda
½ tsp baking powder
½ tsp salt
1 large egg (room temperature)
1 tsp vanilla extract
320g (about 3 medium) mashed overripe bananas
60g (¼ cup) full-fat sour cream (or Greek yogurt)

Kitchen Equipment Needed

You don’t need much to make this loaf, but here’s a quick checklist:

9×5-inch loaf pan
Parchment paper
Mixing bowls
Whisk and silicone spatula
Saucepan (for browning butter)
Wire cooling rack
Measuring cups or kitchen scale
Toothpick or cake tester

Step-by-Step Instructions

1. Brown the Butter

This is what sets this banana bread apart. Melt the butter in a small saucepan over medium heat. Keep cooking and stirring until it foams and turns golden brown, releasing a toasty, nutty aroma—this takes about 5–7 minutes. Immediately transfer to a large mixing bowl and let it cool slightly. This step adds deep flavor and a gourmet edge.

Tip: Watch the butter closely—once it begins to brown, it can burn quickly.

2. Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment paper, leaving some overhang for easy removal.

3. Mix the Dry Ingredients

Into the bowl with the cooled brown butter, whisk in the sugar, cinnamon, nutmeg, baking soda, baking powder, and salt until well combined.

4. Add Wet Ingredients

Stir in the egg, vanilla, mashed bananas, and sour cream. Mix until fully incorporated. Your batter should look rich and creamy.

5. Fold in the Flour

Gently fold in the flour, being careful not to overmix. Overmixing can result in a dense loaf, so stop as soon as the flour disappears.

6. Bake to Perfection

Pour the batter into the prepared loaf pan and smooth the top. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

7. Cool Before Slicing

Allow the bread to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This helps set the structure and prevents soggy bottoms.

Tips for Success

Use very ripe bananas—the browner, the better. They add natural sweetness and moisture.
Don’t skip browning the butter. It’s the secret ingredient that makes this loaf unforgettable.
Measure ingredients by weight for precision and consistent results.
Let the brown butter cool slightly before mixing in sugar and eggs, so you don’t scramble the egg.

Substitutions & Variations

Greek Yogurt Swap: Use full-fat Greek yogurt in place of sour cream for a slightly tangier flavor.
Add Nuts or Chocolate Chips: Fold in ½ cup of chopped walnuts, pecans, or dark chocolate chips for added texture and richness.
Make It Dairy-Free: Use a plant-based butter alternative and dairy-free yogurt to make this suitable for non-dairy diets.
Spice it Up: Add a pinch of ground cloves or cardamom for a deeper spice profile.

How to Store Leftovers

This banana bread keeps exceptionally well—thanks to the sour cream and bananas.

Room Temperature: Store tightly wrapped or in an airtight container for up to 3 days.
Refrigerator: Extend shelf life to 5–6 days by storing in the fridge. Bring to room temperature before serving.
Freezer: Wrap slices or the whole loaf in plastic wrap, then foil, and freeze for up to 3 months. Thaw at room temperature or reheat in the microwave.

What to Serve With Brown Butter Banana Bread

For breakfast: Pair with a latte or strong black coffee.
For dessert: Serve warm with a scoop of vanilla ice cream or a drizzle of caramel sauce.
For snacking: Add a smear of peanut butter or almond butter on top.
For brunch: Serve alongside fresh fruit and mimosas for a sophisticated spread.
