👩🍳 Instructions
1. Make the cake
- Preheat oven to 350°F (175°C). Grease and line multiple cake pans or a 9×13 pan.
- Cream butter, sugars until fluffy. Mix in eggs, sour cream, vanilla.
- Alternate adding dry ingredients and mashed bananas until just combined.
- Bake 25–30 min for layers, or up to 1 hr at lower temp (275°F) for a sheet cake—test with a toothpick.
- Cool completely before frosting.
2. Prep frosting
- Beat cream cheese and butter until creamy. Gradually add powdered sugar.
- Add vanilla and cream until smooth and slightly thick. Adjust sweetness/consistency.
3. Assemble
- Spread frosting between cake layers and frost sides/top.
- Garnish with banana slices, crushed vanilla wafers, toasted nuts, or a dusting of cinnamon.
✨ Variations
- Brown Butter Cream Cheese Frosting: Use browned butter instead of plain for a nutty depth.
- Whipped Cream-Cheese Frosting: Lighter, fluffier texture—fold whipped cream into cream cheese mixture.
- Coffee Twist: Add espresso powder to frosting or batter for a mocha kick.
