Banana Butter Cake – Moist, Rich & Perfectly Sweet!

There’s something magical about the aroma of bananas, butter, and vanilla wafting from the oven — pure comfort in cake form! This Banana Butter Cake is soft, tender, and bursting with ripe banana flavor. It’s the kind of cake that feels just right for lazy mornings, afternoon coffee breaks, or a sweet little dessert after dinner.
Made with simple ingredients and no fancy techniques, this cake delivers a luscious texture thanks to the sour cream (or yogurt), while a hint of vanilla brings everything together in one buttery, banana-kissed bite. Optional nuts add a touch of crunch if you like it a little rustic!

Ingredients
Dry Ingredients:
- 1 1/2 cups (180 g) all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
Wet Ingredients:
- 1/2 cup (115 g) unsalted butter, softened
- 1 cup (200 g) granulated sugar
- 2 large eggs, room temperature
- 1 tsp vanilla extract
- 3 ripe bananas, mashed
- 1/2 cup (120 ml) sour cream or plain yogurt
Optional:
- 1/2 cup (60 g) chopped walnuts or pecans
Instructions
Prep the Pan & Oven
Preheat your oven to 350°F (175°C).
Grease and flour a 9×5-inch loaf pan or a 9-inch round cake pan.
Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
Cream the Butter & Sugar
In a large mixing bowl, use a hand mixer or wooden spoon to cream the softened butter and sugar until light and fluffy — about 2–3 minutes.
Add the Eggs & Vanilla
Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Add the Bananas & Sour Cream
Mix in the mashed bananas until fully combined.
Add the dry ingredients in three parts, alternating with the sour cream, beginning and ending with the flour. Stir just until combined — don’t overmix!
Add Nuts (Optional)
Fold in the chopped nuts, if using.
Bake
Pour the batter into the prepared pan and smooth the top.
Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Cool
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Tips & Variations
- Super ripe bananas (with brown spots!) make for the best flavor and sweetness.
- For a fancier twist, top the batter with banana slices or a sprinkle of cinnamon sugar before baking.
- Add chocolate chips, coconut flakes, or swirls of peanut butter for fun mix-ins.
- Try it with a dollop of Greek yogurt, a drizzle of maple syrup, or a slather of salted butter — heaven!
- Store leftovers in an airtight container for up to 3 days, or freeze for up to 2 months.
