What You’ll Need

Here’s what you’ll need to make this delicious Moist Peanut Butter Banana Cake with Caramel Icing:

Ripe Bananas: Use at least three overripe bananas for optimal sweetness and moisture; they should be speckled brown.
Peanut Butter: Creamy peanut butter works best here; it blends seamlessly into the batter for rich flavor.
Sugar: A mix of granulated and brown sugar gives depth to the sweetness and helps keep the cake moist.
Eggs: Two large eggs help bind everything together while adding richness and structure to your cake.
All-Purpose Flour: Regular flour provides a sturdy base; sift it to ensure there are no lumps in your batter.
Baking Powder: This leavening agent gives lift to your cake, ensuring it remains fluffy and light.
Salt: Just a pinch enhances all flavors while keeping sweetness in check without being overpowering.
Unsalted Butter: Melted butter adds richness; make sure it’s cooled slightly before mixing into your batter.

For the Caramel Icing:

Brown Sugar: The star ingredient in your caramel icing; it adds that deep flavor we all crave!
Heavy Cream: Use full-fat cream for a velvety texture that makes your icing luxurious and smooth.

Cooking Instructions

Follow these simple steps to prepare this delicious Moist Peanut Butter Banana Cake with Caramel Icing:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease and flour two round cake pans so your masterpiece doesn’t stick.

Step 2: Mix Wet Ingredients

In a large mixing bowl, mash those ripe bananas until smooth. Stir in peanut butter, melted butter, eggs, and sugar until well combined.

Step 3: Combine Dry Ingredients

In another bowl, whisk together flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients until just combined—don’t overmix unless you want rubbery cake (not cool).

Step 4: Bake

Divide the batter evenly between the prepared pans. Bake for about 25-30 minutes or until a toothpick inserted in the center comes out clean.

Step 5: Prepare Caramel Icing

While cakes cool down (patience!), combine brown sugar and heavy cream in a saucepan over medium heat. Stir continuously until it reaches a gentle boil; let simmer for about three minutes.

Step 6: Cool & Ice

Let cakes cool completely before removing from pans. Pour warm caramel icing over cooled cakes before serving for that ooey-gooey finish.

Transfer to plates and enjoy each delicious slice topped with extra caramel if you’re feeling indulgent!
