Preheat oven to 350° F. Prepare three 7-inch cake pans with nonstick cooking spray and parchment circles.

Bake for approximately ⏱️ 30 minutes until the cakes bounce back when gently touched or an inserted toothpick comes out clean.
7
Remove the cake pans from the oven and allow the cake layers to cool in the pan for approximately ⏱️ 10-15 minutes. Remove the cake layers from the pan and transfer to a wire rack to cool completely.
8
Level the cake layers with a serrated knife to remove the cake domes to create flat cake layers.

Allow the mixture to cool to room temperature before transferring to a bowl and chilling in the fridge for at least one hour before use.
15
Vanilla Buttercream Frosting
16
Add room temperature butter to a large mixing bowl or the bowl of a stand mixer fitted with a whisk or paddle attachment. Whip the butter for ⏱️ 5 minutes on medium-high speed, scraping down the sides occasionally, until the butter is light, fluffy, and pale in color.
17
Add one half of the powdered sugar and mix on the lowest speed setting until fully combined. Add remaining powdered sugar and continue to mix on low until incorporated.

19
Slowly drizzle in the heavy cream while mixing on low speed. Scrape the sides of the bowl occasionally to ensure the frosting is well mixed.
20
Once the heavy cream is added, turn the speed on the mixer to medium and mix for an additional ⏱️ 3 minutes until smooth.
21
Chocolate Ganache
22
Add chocolate chips to a heat-proof medium bowl.
23
In a microwave-safe bowl, heat heavy cream for about ⏱️ 30-45 seconds until bubbling.
24
Pour the hot cream over the chocolate chips and allow the mixture to sit for a few minutes.
25
Stir the chocolate/cream mixture until smooth and shiny. Transfer to a squeeze bottle or piping bag and cool slightly before adding to the cake.
26
Assembling the Banana Split Cake
27
Place first banana cake layer on an 8-inch cake board. Using an offset spatula, spread a thin, even layer of vanilla buttercream frosting over the cake. Use a piping bag to pipe a thick ring of vanilla buttercream around the edges of the cake.
28
Add strawberry filling inside the buttercream border. Spread the filling evenly with an offset spatula.
29
Add the second cake layer on top of the strawberry filling. Repeat the above process, adding a thin layer of frosting, a buttercream border, and the strawberry filling. Add the final cake layer, bottom side up.
30
Spread a thin layer of buttercream frosting (crumb coat) over the top and sides of the cake using an offset spatula. Use a cake scraper to smooth out the frosting and remove excess buttercream.
31
Chill the cake for ⏱️ 30 minutes to firm up the buttercream frosting.
32
Frost the top and sides of the cake with the vanilla buttercream using an offset spatula. Use a cake scraper to smooth out frosting on the top and sides of the cake. If desired, add a rainbow sprinkle skirt on the bottom of the cake.
33
Chill the cake for an additional ⏱️ 15 minutes to firm up the buttercream.
34
Use a squeeze bottle to create a chocolate ganache drip down the sides of the cake. Immediately add some rainbow sprinkles onto the chocolate ganache drips.
35
Pipe swirls of vanilla buttercream frosting around the top edges of the cake using a Wilton 1M piping tip. Add additional rainbow sprinkles and maraschino cherries onto the buttercream swirls.
