What are Banana Twins?

Banana twins are a type of snack cake that features a banana-flavored sponge with a creamy filling. These twin cakes were individually wrapped, making them perfect for on-the-go snacking.

Second, the process is fun and rewarding, and you’ll end up with a delicious treat that’s perfect for sharing. Plus, who doesn’t love a bit of nostalgia with their snack?

Ingredients and Equipment


To make your own banana twins, you’ll need:

  • 1 ½ cups mashed ripe bananas (about 3 bananas)
  • 1 cup granulated sugar
  • ½ cup brown sugar
  • ½ cup unsalted butter, melted
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup sour cream

For the filling:

  • 1 cup heavy cream
  • 2 tablespoons powdered sugar
  • 1 teaspoon vanilla extract


You’ll need the following equipment:

  • Mixing bowls
  • Hand mixer or stand mixer
  • Measuring cups and spoons
  • Baking sheets
  • Parchment paper
  • Cooling rack
  • Pastry bag with a round tip (for filling)

Preparing the Batter

Mixing the Wet Ingredients

Start by preheating your oven to 350°F (175°C) and lining your baking sheets with parchment paper. In a large mixing bowl, combine the mashed bananas, granulated sugar, brown sugar, melted butter, eggs, and vanilla extract. Use a hand mixer or stand mixer to blend these ingredients until they’re smooth and well-combined.

Combining the Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This step ensures that the leavening agent is evenly distributed throughout the batter.

Bringing It All Together

Gradually add the dry ingredients to the wet mixture, mixing just until combined. Finally, fold in the sour cream. The sour cream adds moisture and tanginess to the batter, resulting in a tender, flavorful cake.

Baking the Cakes

Shaping the Cakes

Spoon the batter onto the prepared baking sheets, forming small, even mounds. Try to keep them uniform in size so they bake evenly. You can use a cookie scoop for this step to make it easier.

Baking Time

Bake the cakes in the preheated oven for 10-12 minutes, or until they’re golden brown and a toothpick inserted into the center comes out clean. Let the cakes cool on the baking sheets for a few minutes before transferring them to a cooling rack to cool completely.

Making the Filling

Whipping the Cream

While the cakes are cooling, prepare the filling. In a mixing bowl, combine the heavy cream, powdered sugar, and vanilla extract. Use a hand mixer or stand mixer to whip the cream until it forms stiff peaks. Be careful not to overwhip, as this can cause the cream to become grainy.

Filling the Cakes

Once the cakes are completely cool, it’s time to fill them. Transfer the whipped cream filling to a pastry bag fitted with a round tip. Pipe a generous amount of filling onto the flat side of one cake, then top it with another cake to form a sandwich. Repeat this process until all the cakes are filled.

Serving and Enjoying

Storing Your Banana Twins

These banana twins are best enjoyed fresh, but you can store them in an airtight container in the refrigerator for up to three days. If you want to make them ahead of time, you can freeze the unfilled cakes and thaw them before filling and serving.

Making It a Fun Activity

Baking banana twins can be a fun activity to do with family or friends. Get everyone involved in the process, from mashing the bananas to piping the filling. It’s a great way to spend time together and create delicious memories.


Recreating the nostalgic banana twin snack at home is a fun and rewarding experience. With fresh ingredients and a bit of love, you can make a treat that’s even better than the store-bought version. Whether you’re reliving childhood memories or introducing this classic snack to a new generation, homemade banana twins are sure to be a hit.
