- Whisk
- Fork (to mash bananas)
- 9 by 13 inch baking dish
- Spatula
- A knife for cutting the butter into the crumble

What You Need
For the cake:
- Three ripe bananas, mashed
- 1/3 cup of melted butter
- 2/3 cup of sugar in granules
- 1/2 cup of brown sugar
- Two big eggs
- 1 teaspoon of vanilla extract
- 1/2 cup of Greek yogurt or sour cream
- Two cups of flour for all purposes
- 1 teaspoon of baking soda
- 1 teaspoon of baking powder
- 1/2 teaspoon of salt
To make the Cinnamon Crumble:

- Brown sugar, 1/4 cup
- 1 teaspoon of cinnamon
- 1/4 cup of cold butter, cut into cubes
How to Bake a Banana Coffee Cake
- Step 1: Get your ingredients ready.
Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish and put it aside. Use a fork to mash the bananas in a big bowl until they are smooth. - Step 2: Mix the wet things together.

Mix the melted butter, granulated sugar, brown sugar, eggs, vanilla, and sour cream into the mashed bananas. Whisk until the mixture is smooth and creamy. - Step 3: Mix the dry ingredients
Mix the flour, baking soda, baking powder, and salt in a different bowl. Add the dry ingredients to the wet mixture a little at a time, stirring until they are just mixed in. - Step 4: Make the Crumble
In a small bowl, combine the brown sugar, cinnamon, and flour. Add the cold, cubed butter and use your fingers or a fork to mix it in until it is crumbly. Put the crumble in the fridge for five minutes to cool it down. - Step 5: Put together and bake
Put the banana batter into the baking dish that has been greased. Spread the crumble topping evenly over the batter. Bake for 40 to 45 minutes, or until a toothpick stuck in the middle comes out clean. - Step 6: Let it cool and serve
Before cutting, let the cake cool for 10 to 15 minutes. Serve warm with a cup of coffee or a glass of milk for the kids!
Helpful Tips
- Bananas Matter: Make sure your bananas are very ripe; the more spots they have, the better. They will make the cake sweet and keep it moist.
- Don’t forget the sour cream; it makes the cake even softer and moister. Plain Greek yogurt works just as well if you don’t have it.
- Chill the Crumble: Put the crumble in the fridge for a few minutes before putting it on top. This will help it stay crumbly while it bakes.
- Family Fun: Let the kids help mash the bananas or put the crumble on top. They’ll love being a part of it!
- To see if the cake is done, stick a toothpick in the middle. You’re good to go if it comes out clean or with only a few crumbs.
Changes and Replacements
- No sour cream? Plain Greek yogurt or even buttermilk will work just as well.
- Want More Crunch? Add chopped walnuts or pecans to the topping for the crumble.
- For a healthier choice, use whole wheat flour instead of half of the flour and coconut sugar instead of brown sugar.
- No Bananas? For a fall-inspired twist, use canned pumpkin instead!
Tips for Getting Ready
The next day, this cake tastes even better! Bake it the night before, let it cool all the way down, and then wrap it up tightly. The flavors get stronger overnight, and it stays perfectly moist.
How to Store and Use Leftovers
- You can keep leftovers in an airtight container at room temperature for up to two days.
- If you want to keep it longer, put it in the fridge for up to five days and microwave each slice for 10 to 15 seconds.
- You can freeze slices for up to two months. Let it thaw at room temperature and enjoy!
