Ingredients You’ll Need

Here’s the absolute best part—you only need a handful of everyday ingredients to make this magical banana cake:

• Ripe Bananas: These are the star of the show, bringing natural sweetness, moisture, and a hint of tropical flavor. The riper, the better! Brown spots on the peel mean intense banana goodness inside.
• Large Eggs: Eggs help bind the ingredients together and keep the cake fluffy. Don’t skip these!
• Vegetable Oil: Keeps the cake incredibly moist without adding any overpowering flavor. You can swap it with melted butter if desired for a richer finish.
• Yellow Cake Mix: This store-bought shortcut is a game-changer. It eliminates the need for measuring flour, sugar, or leavening agents.
• Chocolate Frosting: The ultimate finishing touch! Feel free to use store-bought frosting or whip up your own homemade version for an extra-special treat.

Pro Tip: Make sure the bananas are fully mashed for a smooth, lump-free batter.

Variations

Want to make this recipe your own? Here are some fun twists:

• Peanut Butter Dream: Swap the chocolate frosting for peanut butter frosting or drizzle the cake with melted peanut butter instead.

How to Make 4 Ingredient Banana Cake

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan with non-stick cooking spray to ensure an easy release.

Step 2: Mash the Bananas

In a large mixing bowl, mash the ripe bananas with a fork until smooth. You don’t want large chunks—they’ll disrupt the cake’s texture.

Step 3: Combine Wet Ingredients

Add the eggs and vegetable oil to the mashed bananas. Whisk everything together until well combined.

Step 4: Add Cake Mix

Gradually stir in the yellow cake mix, mixing just until the batter is smooth and lump-free. Avoid overmixing—this can make the cake dense.

Step 5: Bake

Pour the batter into your prepared baking pan. Smooth the top with a spatula, then bake for 45–50 minutes. The cake is ready when a toothpick inserted into the center comes out clean.

Step 6: Cool and Frost

Let the cake cool completely in the pan before frosting with your chocolate frosting or dusting with powdered sugar. Slice, serve, and enjoy!

Pro Tips for Making the Recipe

• Choose Overripe Bananas: Overripe bananas with lots of brown spots guarantee maximum sweetness and the best flavor.
• Don’t Overmix: Stir the batter until just combined. Overmixing can make the cake dense rather than soft and airy.
• Test for Doneness: Start checking the cake around the 45-minute mark to avoid overbaking.
• Cool Before Frosting: A warm cake will cause the frosting to melt, so make sure the cake is fully cooled before you frost it.

How to Serve

This banana cake is a delight on its own, but here are a few ideas to elevate your serving game:

• Simple and Classic: Enjoy it as is, topped with a hearty layer of chocolate frosting.
• A La Mode: Serve warm slices with a scoop of vanilla ice cream for an extra-indulgent dessert.
• Breakfast-Style: Skip the frosting and enjoy a slice with a hot cup of coffee for an irresistible breakfast treat!

Make Ahead and Storage

Storing Leftovers

Store leftover banana cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.

Freezing

Want to save some for later? Wrap individual slices tightly in plastic wrap, then place in a freezer-safe container or bag. Freeze for up to 3 months. Thaw at room temperature before serving.

Reheating

To enjoy warm banana cake, microwave slices for 10–15 seconds. Add frosting after reheating, if desired.

FAQs

1. Can I use a different cake mix flavor?
Absolutely! Feel free to experiment with white cake mix, spice cake mix, or even chocolate cake mix for a fun twist on the original recipe.

2. Can I make this recipe egg-free?
Yes, you can substitute the eggs with unsweetened applesauce (1/4 cup per egg) or mashed banana for a vegan-friendly version.

3. Can I reduce the sweetness?
If you prefer a less sweet cake, use a sugar-free cake mix or skip the frosting and simply dust the finished cake with powdered sugar.

4. Can I make this into cupcakes?
Definitely! Line a muffin tin with cupcake liners, fill each about 2/3 full, and bake at 350°F for 18–22 minutes. Keep an eye on them to avoid overbaking.
