First Birthday Smash Cake {banana cake with marshmallow creme frosting}

There is nothing cuter than watching a baby smash into their first birthday cake! I love seeing the curiosity and excitement on their face as they are given permission to dig into their very own cake and make as big of a mess as they want while everyone cheers them on! Such a fun birthday tradition!

1st Birthday Smash Cake

So as you can imagine, I was so thrilled and flattered when my friend, Robin, asked me to make sweet Ella’s first birthday smash cake! I was also pretty nervous because I’m no cake decorator and I wanted it to be so cute and special for the birthday girl!

Ella is a girly girl so my vision for her smash cake was pink, pink, and more pink! In fact, I think it was the most pink I’ve ever had in my house and I loved it! I always tell Robin that her precious girls give me my “girly fix” in this house full of boys!

I decided to make the same cake I made for Baker on his first birthday! It’s a simple banana cake that’s easy and delicious!

I frosted Baker’s smash cake with a chocolate frosting and topped it off with some sport ball cake balls to fit the theme of his party! All boy!

Fudge Frosting Recipe:

  • 5 ounces unsweetened chocolate, chopped
  • 8 tablespoons butter, room temperature
  • 3 cups powdered sugar, sifted
  • 6 tablespoons milk

Melt chocolate in the top of a double boiler over simmering water. Let cool to room temperature, about 10 minutes. Add butter and beat on high speed with an electric mixer until light and fluffy, about 2 minutes. Add powdered sugar and the milk; beat until smooth. Add more powdered sugar if frosting seems too thin.

For Ella’s cake, I made a fluffy light pink frosting and decorated it with hot pink icing and large pink sprinkles. All girl!

As you can see, the birthday girl had no fear and dug right in to her special cake!

Decorate the tops and sides of the cake as you wish. I pressed jumbo round pink sprinkles around the sides of the cake and piped store-bought hot pink decorator’s icing around the bottom and top of the cake.

Description

A sweet and special cake that any birthday girl or boy would love to smash into!


Ingredients

Banana Cake:

  • 2 tablespoons butter, melted
  • 1/3 cup honey (or 1/2 cup pure maple syrup)
  • 2 large eggs
  • 3/4 cup whole milk
  • 1 teaspoon vanilla
  • 2 cups self-rising flour OR see substitute suggestions in notes
  • 3 large ripe bananas, mashed (about 11/2 cups)

Marshmallow Creme Frosting:

  • 1 jar (7 ounces) marshmallow crème
  • 1 cup (2 sticks) butter, softened
  • 5 teaspoons whole milk
  • 4 cups powdered sugar
  • 23 drops red food color
  • decorative round jumbo sprinkles and icing

Instructions

  1. Preheat oven to 350°F. Lightly grease and flour two 6-inch round cake pans. Set aside.
  2. In a medium bowl, whisk together butter, 1/3 cup honey (or 1/2 cup pure maple syrup), eggs, milk, and vanilla.
  3. Place the flour in a large bowl and make a well in the center. Add the wet ingredients and stir until well combined. Stir in the mashed bananas.
  4. Divide batter evenly between the prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted in the center of each cake comes out clean. Let cakes cool in pan on a wire rack for 30 minutes then invert cakes onto the wire rack to cool completely.
  5. While the cakes are cooling, prepare the frosting. In a large bowl, beat the marshmallow crème, butter and 3 teaspoons milk with an electric mixer on high speed until fluffy, 2-3 minutes. Beat in the powdered sugar 1 cup at a time until smooth. Add remaining 2 teaspoons milk and beat until light and fluffy. Beat in food color until frosting is of your desired color. I added 2 drops for a light pink color.
  6. Once cakes are cool, slice off the top of each cake to make them flat. Spread a few tablespoons of frosting on the bottom of the serving platter or cake stand you plan to use. Place one cake top down on the frosting. Put a generous scoop of frosting on top of the first layer and spread until even. Place the other cake top down on the first layer. Spread the top and sides of the cake evenly with more frosting until completely coated and smooth. You want there to be a fairly thick layer of frosting around the cake so your baby will have lots of frosting to get all over them when smashing it.
  7. Decorate the tops and sides of the cake as you wish. I pressed jumbo round sprinkles around the sides of the cake and piped store-bought decorator’s icing around the bottom and top of the cake.

Notes

To substitute the 2 cups self-rising flour, use 2 cups all-purpose or whole wheat flour, 3 teaspoons baking powder, and 1 teaspoon salt.

  1. Made this for my daughter on her 1st birthday 5 years ago and now I’m making it again for my second daughter on her 1st birthday. Thanks for a great recipe, I always eat the top I level off and maybe the left overs too, so yummy!

  2. I’m making this in a 9×13 pan and cutting out my cake circles from that. I’m okay with a smaller cake but wondering if I’ll need to adjust baking time? Thanks

    1. Hi Mallorie! I bet that worked great! It would probably bake about the same time as the two 6-inch rounds would. Hope it turned out great and sorry for the delayed response!

  3. Hi there! I know this is an older post but would whole wheat pastry flour be an okay substitute?

    I’m really excited I found this recipe and can’t wait to try it out!

    1. Hi Kayla! Absolutely, to substitute the 2 cups self-rising flour, use 2 cups whole wheat pastry flour, 3 teaspoons baking powder and 1 teaspoon salt. Enjoy!

  4. Hi There! I’m making a cake for my guys 1st birthday. Is it possible to sub the bananas for pumpkin? He loves everything PuMpkin!! TIA!
