- The cake can be made 1 day ahead—store covered at room temperature.
- For a nutty variation, add 1 cup chopped walnuts or pecans to the batter.
Frequently Asked Questions
Can I use frozen bananas for this cake?
Absolutely! Thaw frozen bananas completely and drain any excess liquid before mashing. Frozen bananas often have even more concentrated sweetness, which works beautifully in this Double Chocolate Banana Layer Cake. Just be sure to measure after thawing and draining, not while frozen.
How should I store leftover cake?
Store any leftover Double Chocolate Banana Layer Cake covered at room temperature for up to 2 days, or refrigerate for up to 5 days. The flavors actually develop more over time. For longer storage, you can freeze individual slices wrapped tightly in plastic wrap and foil for up to 3 months.
Can I make this cake gluten-free?
Yes, you can substitute a gluten-free all-purpose flour blend for the regular flour. Look for one that contains xanthan gum or add 1/2 teaspoon xanthan gum to the dry ingredients. The texture may be slightly denser but still delicious.
What’s the best way to mash bananas for this recipe?
For the smoothest texture in your Double Chocolate Banana Layer Cake, use a fork or potato masher to thoroughly mash ripe bananas until no large chunks remain. For an even finer texture, you can briefly pulse them in a food processor, but don’t liquefy them.
Can I use milk chocolate instead of semisweet?
While you can use milk chocolate, the cake will be significantly sweeter. Semisweet chocolate provides the perfect balance against the sweetness of the bananas and sugar. If using milk chocolate, you might want to reduce the sugar in the cake by 1/4 cup.
