Baking Your Masterpiece
- Get Your Oven Ready
- Set your oven to 325°F (165°C) and get your 8x8-inch pan ready by giving it a good spray or lining it with some parchment.
- Put Together Dry Stuff
- Grab a big bowl and mix your flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Just set it aside for now.
- Blend Wet Ingredients
- In another bowl, beat together your sugar, oil, and applesauce. Then add in the eggs, vanilla, and those mashed bananas, mixing just enough to bring everything together.
- Finish Up and Bake
- Gently mix your dry ingredients into the wet stuff, being careful not to overdo it. Pour everything into your pan and bake about 25-30 minutes. You'll know it's done when a toothpick comes out clean. Let it cool completely before you add any frosting.
Whipping Up Your Topping
- Handle the Butter First
- Put your butter in a small pot over medium heat until it melts. If you want extra flavor, keep cooking until it turns a nice amber color and smells nutty. Let it cool down before using.
- Create Your Creamy Topping
- With a mixer, beat together your cooled butter, powdered sugar, vanilla, and cream until it's all smooth and fluffy. If it's too thick, add a bit more cream - too thin, just sprinkle in more powdered sugar.

Adding The Finishing Touches
Once your cake has cooled down, spread that luscious buttercream all over the top. Scatter some chopped walnuts across the frosting if you want that extra bit of crunch and flavor. Cut into squares and get ready to impress. This cake doesn't just taste amazing - it looks gorgeous too, making it perfect for any table.
Keeping It Fresh
Got leftovers? Keep them in a sealed container at room temp for up to 3 days. Want to save some for later? Wrap single slices in plastic and pop them in the freezer for up to 3 months. Planning ahead? You can bake the cake early, wrap it up tight and stick it in the fridge. Just add the frosting right before you're ready to serve so everything tastes fresh and amazing.
Frequently Asked Questions
- → What kind of bananas work best?
Overripe bananas with dark spots are ideal. They're sweeter and mash easier, creating a moist and flavorful cake.
- → Can I leave out the applesauce?
Applesauce makes the cake extra soft and cuts down the oil. If you're out, swap it with the same amount of oil. The texture might change slightly.
- → What’s the best way to store it?
Keep the frosted cake in an airtight container at room temperature for up to 3 days. For longer storage, pop it in the fridge for up to a week.
- → Can I prepare it early?
Sure! Bake it the day before and store it without frosting. Spread the buttercream just before serving for freshest taste.
- → Why separate dry and wet ingredients?
Separating dry ingredients ensures spices and baking powder spread evenly. Gradually mixing them with wet avoids making the cake dense or heavy.
