Ingredients Breakdown
Understanding each ingredient ensures perfect texture and flavor.
For the Banana Bread Cake
3 large ripe bananas (very spotty = best flavor)
2 cups all-purpose flour
1 ½ cups granulated sugar
½ cup brown sugar
¾ cup unsalted butter, melted
½ cup sour cream or Greek yogurt
3 large eggs (room temperature)
1 teaspoon vanilla extract
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon salt
Optional: ½ teaspoon cinnamon
Why these ingredients matter:

Overripe bananas provide natural sweetness and moisture.
Brown sugar adds depth and slight caramel notes.
Sour cream or yogurt keeps the cake tender.
Butter adds richness.
Eggs create structure and lift.
For the Cream Cheese Frosting
8 oz (225g) full-fat cream cheese, softened
½ cup unsalted butter, softened
3–4 cups powdered sugar
1 teaspoon vanilla extract
Pinch of salt
The frosting should be smooth, creamy, and spreadable — not too stiff, not too runny.
Step-by-Step Instructions
Step 1: Prepare the Pan
Preheat oven to 350°F (175°C).
Grease and line a 9×13 inch baking pan.
Set aside.
Step 2: Mash the Bananas
In a large bowl:
Mash bananas until mostly smooth but slightly textured.
Avoid making them completely liquid — small chunks add moisture pockets.
Step 3: Mix the Wet Ingredients
Add to the mashed bananas:
Melted butter
Granulated sugar and brown sugar
Eggs
Sour cream
Vanilla
Whisk until fully combined.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk:
Flour
Baking soda
Baking powder
Salt
Cinnamon (optional)
Step 5: Combine Wet and Dry
Gradually fold dry ingredients into wet mixture.
Stir gently until just combined.
Important:
Do not overmix — this keeps the banana cake soft and fluffy.
Step 6: Bake
Pour batter evenly into prepared pan.
Bake for 35–40 minutes.
Insert a toothpick — it should come out clean or with a few moist crumbs.
Allow cake to cool completely before frosting.
Making the Perfect Cream Cheese Frosting
Cream cheese frosting is the signature finish of this cake.
Instructions:
Beat softened cream cheese and butter until smooth and fluffy (2–3 minutes).
Gradually add powdered sugar.
Mix in vanilla and salt.
Adjusting Consistency:
Too thick? Add 1 tablespoon milk.
Too thin? Add more powdered sugar.
Spread evenly over cooled cake using an offset spatula.
