Prep and bake
- Preheat the oven to 325°F and grease and flour a 12-cup bundt pan very thoroughly, coating every crevice so batter releases cleanly.
- Beat the butter and sugar until light and fluffy, then add the eggs one at a time and mix in the vanilla and mashed bananas until smooth.
- In 3 additions, alternate folding in the flour mixture (flour, baking soda, salt, cinnamon) and the sour cream, mixing just until no dry streaks remain each time.
- Pour the batter into the prepared bundt pan and bake for 60–70 minutes, until a toothpick inserted in the center comes out clean with a golden top.
- Cool the cake in the pan for 20 minutes before inverting, then cool completely before glazing so the glaze stays thick and doesn’t melt.
Make and glaze
- Beat the cream cheese, powdered sugar, milk, and vanilla until smooth, thick, and pourable.
- Pour the cream cheese glaze over the cooled cake so it cascades down every ridge for a glossy finish.
Notes
Pro tip: grease-plus-flour really matters for bundt cakes—run a light coat into the deepest ridges so the cake releases without tearing. Store covered at room temperature for up to 3 days, or refrigerate up to 5 days; freeze unfrosted for up to 2 months, then thaw and glaze after thawing. For a dairy-light swap, use a lactose-free cream cheese and sour cream in the same amounts (texture should remain similar).
