These muffins are the sort of thing I reach for when I have a few very ripe bananas on the counter and want something reliable, flavorful, and fast. This version leans on a banana cake mix and instant pudding mix to create moist, tender muffins with a pronounced banana taste and a nice nutty crunch from the walnuts.
They bake up consistently in a standard 12-cup pan, which means they’re friendly for batch baking and sharing. The method is straightforward: mash, mix, fold, fill, and bake. It’s the practical kind of recipe that performs in a busy kitchen.
Below you’ll find the exact ingredients and step-by-step directions, troubleshooting notes, optional seasonal tweaks, and storage tips so you get the same great results every time.
Ingredients at a Glance
- 1 cup mashed ripe banana (about 3 bananas) — provides the base banana flavor and moisture; measure after mashing for accuracy.
- 1 box banana cake mix (15.25 ounces, I recommend Dolly Parton’s Banana Cake Mix) — the structure and dominant cake flavor; use the full box.
- 2 tablespoons all-purpose flour — lightens the batter slightly and helps with structure.
- 1 box instant banana pudding mix (4-serving) — adds richness and extra banana flavor, plus helps keep muffins moist.
- 4 eggs — binders that add lift and richness.
- 1/2 cup vegetable oil — fat for tenderness and moist texture; use the measured amount.
- 3/4 teaspoon ground cinnamon — subtle warmth that complements the banana.
- 1/2 cup water — thins the batter to the right consistency; add exactly as listed.
- 1 teaspoon banana extract — boosts banana aroma and flavor.
- 1 cup chopped walnuts — provides crunch and nutty contrast; fold in last so nuts stay distributed.
Otis Spunkmeyer Banana Nut Muffins in Steps
- Preheat the oven to 350°F. Line a regular-sized (12-cup) muffin pan with paper liners.
- Mash ripe bananas until smooth and measure 1 cup (about 3 bananas).
- In a large bowl, combine the mashed banana, 4 eggs, 1/2 cup vegetable oil, 1/2 cup water, and 1 teaspoon banana extract. Use an electric mixer on low–medium speed or a whisk to blend until combined, about 1 minute.
- Add 1 box (15.25 oz) banana cake mix, 1 box instant banana pudding mix (4-serving), 2 tablespoons all-purpose flour, and 3/4 teaspoon ground cinnamon to the wet mixture. Mix on low–medium speed until smooth and no large lumps remain, about 2–3 minutes.
- Fold in 1 cup chopped walnuts with a spatula until evenly distributed.
- Fill each prepared muffin cup about 3/4 full with batter.
- Bake in the preheated oven for about 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
- Store cooled muffins in an airtight container.
Why You’ll Keep Making It
These muffins are reliable. The combination of banana cake mix and instant pudding gives consistent moisture and a tender crumb without fuss. You don’t need to weigh or sift anything complicated; the boxed mixes simplify the process while still delivering a bakery-like result.
They’re versatile too: great for breakfast, good for lunchboxes, and sturdy enough to travel. The walnuts add texture and balance the sweetness. If you like a pronounced banana flavor, the banana extract plus real mashed banana does the trick.
If You’re Out Of…
Out of walnuts? You can omit them entirely and the muffins will still be moist and tender. If you have other nuts you use often, a similar quantity of chopped nuts will work in the same role. No nuts preserves the banana texture and avoids any unwanted bitterness from over-toasted nuts.
Out of banana extract? You’ll still have a strong banana presence from the mashed bananas and the pudding and cake mixes; the extract is an enhancer, not a requirement. Skip it rather than substitute without adjusting quantities.
Gear Checklist
- Muffin pan (regular 12-cup)
- Paper liners (or nonstick spray)
- Large mixing bowl
- Electric mixer or whisk
- Rubber spatula for folding
- Measuring cups and spoons
- Wire cooling rack
- Toothpick for doneness checks
Things That Go Wrong
Dense, gummy muffins: that can happen if the batter is overmixed after adding the dry ingredients. Mix until smooth and then stop. The instruction to mix 2–3 minutes at low–medium is to ensure no dry lumps remain, but don’t whip aggressively.
Muffins that fall or sink in the middle: opening the oven door too early can cause this; resist peeking for the first 15 minutes. Also confirm your oven temperature; an oven running too hot will brown the exterior before the center sets, while an oven too cool can produce heavy muffins.
Dry muffins: double-check you used 1/2 cup vegetable oil and 1/2 cup water as listed, and that you measured 1 cup mashed bananas (measure after mashing). Under-measuring wet ingredients or overbaking are the usual culprits.
Seasonal Flavor Boosts
Autumn: a pinch more cinnamon or a small sprinkle of nutmeg pairs nicely with banana and walnuts. A light drizzle of maple glaze (after cooling) makes them feel seasonal.
Winter: fold in a few dark chocolate chips with the walnuts for a richer muffin that still highlights banana.
Spring/Summer: top muffins before baking with a few walnut halves or a coarse sugar sprinkle for a pretty finish and a slight crunch.
Method to the Madness
Why this combo works: the banana cake mix supplies structure and flavor, while the instant banana pudding mix adds body, moisture, and an almost custardy crumb without adding extra liquid. Using mashed bananas gives real fruit texture and natural sweetness. The oil keeps crumb tenderness that butter alone might not provide in this recipe format.
Folding the walnuts rather than beating them in preserves their texture and prevents the batter from becoming too aerated. Filling cups about 3/4 full gives the muffins enough room to rise without spilling over.
Save It for Later
Store cooled muffins in an airtight container at room temperature for 2–3 days. For longer storage, freeze cooled muffins individually wrapped in plastic wrap or in a sealed freezer bag for up to 2 months. To reheat from frozen, thaw at room temperature or warm briefly in a 325°F oven for 8–10 minutes.
If you plan to freeze, skip any fresh toppings and add them after reheating where possible.
FAQ
Q: Can I make these without paper liners? A: Yes. Grease the wells well with nonstick spray or brush with oil, and allow the muffins to cool slightly before removing.
Q: Will the flavor be too artificial because of the cake mix? A: The mashed bananas and pudding mix round out the cake mix base. The result is a pronounced but pleasant banana flavor — the cake mix does not dominate if you use ripe bananas and the banana extract as directed.
Q: Can I halve the recipe? A: Yes. Use a smaller bowl and reduce each ingredient proportionally, keeping the order and method the same. Bake time may vary slightly; check for doneness at around 18 minutes.
Q: My muffins browned on top before they were done. What happened? A: Your oven may run hot. Either lower the temperature by 15–25°F next time or tent the pan with foil after the tops reach your desired brownness and continue baking until a toothpick comes out clean.
