🍫🍌 Chocolate Banana Layer Cake

Rich. Moist. Bakery-Style Indulgence.

This Chocolate Banana Layer Cake is the ultimate combination of deep chocolate flavor and naturally sweet, ripe bananas. Moist chocolate layers meet a silky banana cream filling and glossy dark chocolate ganache — creating a cake that’s elegant, decadent, and unforgettable.

❓ FAQ

Can I substitute bananas?
Yes — applesauce works for moisture, but flavor will differ.

Can I use buttercream instead of banana filling?
Absolutely. Chocolate or vanilla buttercream pairs beautifully.

Can I make this ahead?
Yes. Bake layers a day in advance and assemble the next day.
