In a large mixing bowl, beat together the butter, sugar, and sour cream until light and fluffy (about 2–3 minutes). Add eggs one at a time, mixing well after each addition. Stir in vanilla extract. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Fold in the mashed banana mixture gently.
Once the cake is completely cool, remove it from the freezer and frost generously with the cream cheese frosting. You can leave it rustic or spread it smooth for a polished look.

Crazy Banana Cake is a retro-style dessert known for its incredibly moist crumb, sweet banana flavor, and tangy cream cheese frosting.
What sets this cake apart is the unusual method: baking at a higher temperature and then immediately cooling it in the freezer to lock in moisture.
Here are tips and serving tricks to make your Crazy Banana Cake truly unforgettable.
The spottier, the better! Bananas with lots of black spots are sweeter and more aromatic, giving your cake that intense banana flavor. If your bananas aren't ripe enough, you can bake them in the oven at 300°F (150°C) for 15 minutes to soften and sweeten them quickly.
What makes this cake "crazy" is the technique of placing the freshly baked, still-hot cake into the freezer immediately after baking. This cools the cake rapidly, sealing in moisture and creating a super soft texture. Place the cake (in its pan) on a folded towel in the freezer for about 30–45 minutes.
Pro Tip: Make sure your cake pan is freezer-safe and your freezer has space before you start baking.
Ensure your butter, eggs, and buttermilk are at room temperature before mixing. This helps create a smoother batter and promotes even baking.
Buttermilk reacts with baking soda to help the cake rise and stay soft. If you don’t have buttermilk, substitute with a mix of 1 tbsp lemon juice or vinegar + enough milk to make 1 cup. Let it sit for 5 minutes before using.
Once you combine wet and dry ingredients, mix only until just combined. Overmixing will result in a dense, rubbery texture instead of a light and tender crumb.
For clean and even slices, dip a sharp knife in hot water, wipe it dry, and slice the cake. Repeat between cuts.
This cake tastes amazing both chilled (firmer, denser texture) and at room temp (super soft and moist). Try both ways and see what you prefer.
Crazy Banana Cake tastes even better the next day. Bake and frost it a day in advance and store it covered in the refrigerator. The banana flavor deepens overnight.

This not only adds texture but also elevates the presentation.
