A classic recipe made quicker and more foolproof by using a box cake mix. These cake mix banana muffins are simple to prepare and reliably delicious every time.

I usually enjoy baking from scratch, but when time is tight I keep a box of cake mix on hand for shortcuts. Adding mashed bananas to cake mix creates moist, flavorful muffins with minimal effort — a perfect quick-fix recipe when your bananas are overripe.

This recipe is beginner-friendly, requires just one bowl, and takes only minutes to prepare. If you want an easy, reliable banana muffin that still tastes homemade, this is a great option.

Cake Mix Banana Muffin Ingredients

{Full recipe at the bottom}

• 3 overripe bananas, mashed
• 3 eggs
• 1/2 cup vegetable oil or 1/2 cup (1 stick) melted butter
• 1 (15 ounce / 432 g) box yellow cake mix

Only four ingredients are needed. This makes the recipe ideal for using up overripe bananas without fuss. The result is fluffy, moist muffins with a light, cake-like texture that’s perfect for breakfast or a snack.

How to Make Banana Muffins with Cake Mix

Making these muffins is straightforward and mess-free. No baking soda or extra leavening required — just mix and bake. Here’s an easy step-by-step:

1. Preheat oven to 350°F (175°C). Line a muffin pan with liners or spray with nonstick spray.
2. Combine the bananas, eggs, and oil or melted butter in a large bowl and mix until smooth.
3. Add the cake mix and gently stir until just combined. Do not overmix.
4. Scoop batter into the muffin cups filling each about 3/4 full.
5. Bake 18–20 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
6. Cool in the pan for 10 minutes, then transfer to a wire rack to finish cooling.

This recipe yields 18 standard muffins. If you prefer larger bakery-style muffins, know that the batter is generous and may not produce twelve large muffins successfully; it’s designed for 18 regular muffins.

The oil (or butter) and bananas keep the muffins tender and moist. These muffins are lighter than dense traditional banana bread, so they feel more like cake-style muffins, which many people enjoy for variety and a softer crumb.

They’re also ideal for baking with kids or for beginners: minimal measuring, one bowl, and quick results make the process low-stress and fun.

Variations and Add-Ins

Yellow cake mix is versatile, but you can use other flavors to change the character of the muffins:

• Chocolate cake mix — for a chocolate-banana twist
• White cake mix — for a milder, sweeter base
• Spice cake mix — for warm, autumnal flavor

Other simple additions:

• Top with a streusel before baking
• Add a teaspoon of cinnamon or a splash of vanilla extract to the batter
• Fold in chopped nuts, semisweet chocolate chips, or blueberries

You can make the recipe gluten-free or sugar-free by choosing the appropriate cake mix variety. The recipe adapts well to dietary needs and flavor preferences.

How to Store Cake Mix Banana Muffins

Store muffins in an airtight container, resealable bag, or covered with plastic wrap or foil. They keep well at room temperature for 2–3 days. To reduce condensation and sogginess, line the bottom of the container with a paper towel before placing muffins inside.

These muffins are a great choice for busy mornings or anytime you need a quick homemade treat. They’re fast, forgiving, and crowd-pleasing — a convenient way to turn overripe bananas into something everyone will enjoy.
