We had a couple of bananas sitting in our fruit bowl this weekend that were looking pret-ty ripe. They were leftover from Ben’s last week of marathon training, as he ran the London Marathon last weekend! So instead of baking last week, I was standing on the sidelines, cheering on thousands of runners as we waited for Ben to pass. He did really well and finished in 4:09:32, not bad for a first marathon!
Back to the bananas…Their depressingly faded yellow peels covered in brown freckles were just begging to be put out of their misery. Instead of tossing them, I decided to make an old favorite: Elvis cupcakes.
Why Elvis? Because apparently the man loved peanut butter and banana sandwiches. Only these cakes take it a step further with a chocolate buttercream frosting. You may now be wondering where the peanut butter is if it isn’t in the frosting and the answer is the best surprise of this cake: a creamy peanut butter center!
While the flavor combination sounds like a strange amalgamation, you’d be amazed at how good these cakes taste!
Ingredients
For the cupcakes (makes 9):
- 1 cup + 2 Tablespoons flour (preferably cake flour, if you have it)
- 1/2 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
- 1 whole overly ripe banana
- 2 Tablespoons buttermilk
- 1/2 teaspoon vanilla
- 1/4 cup (58 grams) butter, softened
- 1/2 cup + 2 Tablespoons + 1 1/4 teaspoons sugar
- 1 egg
For the peanut butter filling:
- 1/3 cup creamy peanut butter
- 1 Tablespoon butter, softened
- 3 1/2 Tablespoons icing sugar
For the chocolate buttercream:
- 1/2 cup (115 grams) butter, softened
- 1 Tablespoon milk
- 3 ounces semisweet chocolate
- 1/2 teaspoon vanilla
- 5/8 cup icing sugar
Directions
1. Preheat oven to 350° F (approx 175°C). Place cupcake liners into the pan.
2. In a medium bowl, sift together the flour, baking powder, baking soda, and salt. In a smaller bowl, mix the vanilla and buttermilk.
3. In the bowl of your mixer, cream together the butter and sugar until light and fluffy, then beat in the egg. Once everything is incorporated, mash in the banana and mix well.
4. Stir in the sifted dry ingredients, alternating each addition with the buttermilk mixture. Make sure everything is blended in and smooth before adding the next addition. Once the batter is completely mixed, fill your prepared cupcake pans – filling each cup about 2/3 full.
5. Bake the cakes for about 17 minutes, or until a cake tester comes out clean. Rotate the pans halfway through the baking time. Once they are ready, let them cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
6. To make the peanut butter filling, beat the peanut butter and butter together until creamy. Sift the icing sugar into the bowl and beat until light and fluffy, about 2 minutes. Cut a hole into the top of each cupcake and spoon the filling into the hole, or using a piping bag with a filling tip (my method of choice).
7. To make the chocolate buttercream, melt the chocolate in the top of a double boiler until no clumps remain, and it’s completely smooth. Remove from the heat and allow to cool while you prepare the rest (about 5 – 10 min).
8. In medium sized bowl, beat butter for 3 minutes, until very very creamy. Add the milk and beat until smooth. Add the cooled melted chocolate and beat well. Add vanilla and whip for 3 more minutes. Gradually add the sugar and beat until it’s nice and airy, then fill a piping bag and pipe onto the cakes.
