Prep and bake
- Preheat the oven to 350°F and thoroughly grease and flour a standard bundt pan so the ridges release cleanly.
- Whisk melted butter, sugar, eggs, and vanilla into the mashed bananas until smooth.
- Stir in the sour cream until the batter looks evenly combined.
- Fold in the all-purpose flour, baking soda, salt, and cinnamon just until no dry streaks remain, then fold in walnuts if using.
- Pour the batter into the bundt pan and tap the pan on the counter 2–3 times to release air bubbles.
- Bake for 45–55 minutes, until a toothpick comes out clean and the top is golden.
Cool and glaze
- Cool the banana bread in the pan for 15 minutes to firm up the crumb before inverting.
- Invert onto a plate, then drizzle the vanilla glaze over the cooled bread so it runs down every ridge and pools at the base.
Notes
Pro tip: let the bundt cool fully enough to release without tearing; if you glaze while it’s too warm, the glaze can thin and soak. Store covered at room temperature for up to 3 days or refrigerate up to 5 days; rewarm 10–15 seconds in the microwave for a softer texture. Freezing is yes—freeze slices wrapped well for up to 2 months. For a lighter option, use reduced-fat sour cream (same amount) for a slightly lower-fat crumb while keeping the moist texture.
