    My Banana Snack Cake is a fluffy banana cake topped with rich peanut butter honey buttercream. This moist easy banana cake gets an extra flavor boost from sour cream and cinnamon.

    Banana bread had its moment in 2020, but I still love the flavor and am always looking for new baked banana snack ideas. This moist banana cake is great for snacking, dessert, or even as a dish to add to your next brunch table.

    If you have 2 bananas browning on your counter, you're ready for this snack cake recipe! And if you have even more, try my Banana Nutella Muffins or Honey Banana Bread!

    See recipe card below for a full list of ingredients and measurements.

    Substitutions & Variations

    • Add chopped nuts to the batter for extra crunch. Walnuts are a great banana bread addition!

    Step by Step Instructions

    Mashing overripe bananas in a bowl with a fork.

    Step 1: Mash brown bananas in a bowl using a fork, electric mixer, or potato masher.

    Whisking flour, baking soda, salt, and cinnamon in a bowl.

    Step 2: In a separate bowl, whisk together flour, baking soda, salt, and cinnamon.

    Butter, brown sugar, egg, vanilla extract, sour cream, and bananas mixed in a bowl.

    Step 3: Cream the room temperature butter and brown sugar until light and fluffy. Mix in the egg, vanilla extract, and sour cream, then add the mashed bananas to combine.

    Banana cake batter in an 8x8 inch pan lined with parchment paper.

    Step 4: Stir the dry ingredients into the banana mixture until just combined, then pour the batter into a parchment-lined 8x8 pan and bake at 350°F until the top is golden and a toothpick comes out of the center clean. Transfer to a wire rack to cool completely once it's cool enough to touch.

    Step 5: To make the frosting, mix together the softened butter, peanut butter, honey, and powdered sugar. Add milk or cream if the frosting is too thick.

    Step 6: Frost the completely cooled cake. Sprinkle honey roasted peanuts and drizzle honey on top, if desired.

    Expert Baking Tips

    1. If your bananas are yellow but not quite overripe, you can roast them in a 350°F oven in the peel until they are soft and fragrant.
    2. Make sure all of your wet ingredients are at room temperature so they are easy to cream together.
    3. I recommend spraying the pan with oil and then lining sheets of parchment paper perpendicular across it (folding over the edges) so that it's easy to pull out of the pan.

    Recipe FAQs

    What makes this better than banana bread?

    It's made in an 8x8 inch pan that cuts into 9-16 little square slices - perfect for snacking! It also has delicious frosting on top! Or you can leave the frosting off and have even more surface area of the soft, moist top (AKA my favorite part of banana bread!) It also takes less time to bake than a loaf!

    How should I store leftovers?

    Frosted cake should be stored in the refrigerator for up to 1 week. If it's unfrosted, it can be stored at room temperature.

    What else can I use for the frosting?

    It's delicious unfrosted, or I'd recommend trying a cream cheese frosting! Try cutting the recipe in half from my Cowboy Cookie Cake. If you're feeling chocolatey, try the whipped chocolate ganache from my Banoffee Cupcakes!

    Store unfrosted banana cake in an airtight container on the counter for 3 days.

    Refrigerator

    You can refrigerate the frosted cake for up to 1 week.

    Freezing Instructions

    Store cooled, frosted or unfrosted cake in a freezer-safe container for up to 1 month.

      My mom was a star in the kitchen and made a Banana Cake that I even requested for a birthday, but this Banana Snack Cake really kicks things up a notch! The cake caramelizes on top so it's perfect without the peanut butter frosting, but why do that? Whipped light and oh so spreadable it really is the icing on the cake! Make it once and you'll be making it over and over again!
