Ingredients for Banana Cake Filling
Gather these items:
- 2 large ripe bananas (spotted, not mushy)
- 1/3 cup granulated sugar
- 2 tablespoons cornstarch
- Pinch of salt
- 1 tablespoon lemon juice
- 1 cup whole milk
- 2 large egg yolks
- 2 tablespoons unsalted butter
- 1 teaspoon vanilla extract
- 1 tablespoon heavy cream (optional)
- 1/4 teaspoon cinnamon or nutmeg (optional)
How to Make Banana Cake Filling Step-by-Step
- Step 1: Mash the bananas in a medium bowl until mostly smooth, leaving a few small lumps if desired. Stir in the lemon juice and set aside.
- Step 2: In a medium saucepan, whisk together the granulated sugar, cornstarch, and a pinch of salt.
- Step 3: Gradually whisk in the whole milk until smooth. Add the egg yolks and mashed banana mixture, then stir until fully combined.
- Step 4: Place the saucepan over medium heat. Stir constantly until the mixture thickens to a custard-like consistency, about 6 to 8 minutes. Remove from heat once it bubbles gently.
