Method
Prep and mix the batter
- Preheat the oven to 325°F. Grease and flour a 12-cup bundt pan very thoroughly so every crevice is coated.
- Beat the butter and sugar until light and fluffy. Mix in the eggs one at a time, then add the vanilla extract and mashed bananas.
- Alternate folding in the dry ingredients and sour cream in three additions. Use the flour mixture (flour, baking soda, salt, cinnamon) for the dry parts and sour cream for the wet parts.
Bake
- Pour the batter into the prepared bundt pan. Bake at 325°F for 60–70 minutes, until a toothpick comes out clean.
Cool and glaze
- Cool the cake in the pan for 20 minutes before inverting. Cool completely before glazing so the glaze stays thick and doesn’t melt away.
- Beat the cream cheese, powdered sugar, milk, and vanilla until smooth. Pour over the cooled cake so it drips generously across every ridge.
Notes
Pro tip: grease-and-flour the bundt pan obsessively—getting into every crevice helps you unmold a crisp golden crust and clean ridges for the glaze to cascade. Store covered at room temperature up to 2 days or refrigerate up to 5 days; freeze whole or sliced up to 2 months (glaze after thawing for best texture). For a lighter option, use reduced-fat cream cheese in the glaze and swap half the butter for a neutral oil to reduce saturated fat while keeping the cake moist.
