Strawberry Banana Milkshake Cake – light and fluffy banana cake layers, strawberry cream filling, fresh strawberries and whipped vanilla buttercream.
Strawberry Banana Milkshake Cake
Even though summer is wrapping up and school shopping is underway, I still have so many summer-inspired cake ideas! Not sure I’ll get to them all this year, but I’m so excited to share this Strawberry Banana Milkshake Cake with you! With light and fluffy banana cake layers, strawberry cream filling, fresh strawberries and bananas, and a whipped vanilla buttercream, this cake will make you feel like you’re sitting at an old-fashioned soda bar, sipping and strawberry banana milkshake!
These light and fluffy banana cake layers are based off my Confetti Cake layers. I decided to go with a more subtle banana flavor, compared to a traditional banana cake (i.e. banana bread type flavor). I think you’ll love the lightness of these layers and still appreciate the banana flavor.
Strawberry Cream Filling
For the filling, I used the whipped raspberry filling from my Chocolate Raspberry Swiss Roll and subbed freeze dried strawberries for the raspberries. You are going to LOVE how easy this filling is to make. Just grab your blender or food processor, add the freeze dried fruit, then the heavy whipping cream (as much fat as you can find) and the granulated sugar. Pulse for a few minutes and you’ll have a thick and creamy filling. Best part – it’s stable enough to hold the cake layers!
Garnish and Filling Add-Ins
In addition to the strawberry cream filling in this Strawberry Banana Milkshake Cake, I added fresh strawberries and banana chips. I love that the banana chips hold their crunch after the cake has been frozen or sitting out a bit. I also think fresh bananas would be delicious between the layers with the strawberry slices. Just remember, though – only use fresh bananas if you’re making the cake the same day as when you serve it. Fresh bananas won’t hold up well in the freezer, if you plan to store the cake.
To top this cake off, I decided to go with my vanilla buttercream, a.k.a The Best Vanilla Buttercream. This buttercream frosting is light and fluffy and doesn’t overwhelm any of the other flavors. It’s almost like adding the ice cream element to these milkshake flavors.
I then used Americolor food gel Soft Pink and Egg Yellow. Just a tad of each!
