These muffins are a classic: tender banana crumb studded with walnuts and a whisper of banana pudding for extra banana-forward flavor. They bake up tall with a soft crumb and a slightly crisp top—perfect for morning coffee or an afternoon snack.

There’s nothing fussy here. A boxed banana cake mix plus instant banana pudding speeds things along, mashed ripe bananas add real fruit flavor, and a touch of banana extract amplifies the whole thing. If you want a bakery-style shortcut without losing homemade character, this is it.

Below you’ll find a clear ingredient list with quick notes and a step-by-step method that follows the original directions but in a more usable format. I also include troubleshooting, gear, and ways to vary the muffins by season.

Ingredients at a Glance

• 1 cup mashed ripe banana (about 3 bananas) — Provides moisture, natural sweetness, and banana flavor. Use very ripe bananas with brown spots for best flavor.
• 1 box banana cake mix (15.25 ounces) — The base of the batter; gives structure and flavor. The source suggests Dolly Parton’s Banana Cake Mix but any standard banana cake mix will work.
• 2 tablespoons all-purpose flour — Helps stabilize the batter and prevent excessive spread.
• 1 box instant banana pudding mix (4 servings) — Adds concentrated banana flavor and helps tenderize the crumb.
• 4 eggs — Bind the batter and provide lift; room temperature eggs mix more evenly.
• 1/2 cup vegetable oil — Keeps muffins moist; neutral-flavored oil is recommended.
• 3/4 teaspoon ground cinnamon — Warms the flavor profile and complements the banana.
• 1/2 cup water — Thins the batter to the proper consistency and hydrates dry mixes.
• 1 teaspoon banana extract — Intensifies banana flavor; optional but recommended for a pronounced banana note.
• 1 cup chopped walnuts — Adds crunch and a toasty, slightly bitter contrast to the sweet muffins; toast them briefly for extra depth if you like.

Otis Spunkmeyer Banana Nut Muffins in Steps

1. Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin pan with paper liners or lightly grease the cups.
2. In a large mixing bowl, add 1 cup mashed ripe banana (about 3 bananas).
3. Add 1 box banana cake mix (15.25 ounces) to the bowl with the mashed banana.
4. Sift or sprinkle in 2 tablespoons all-purpose flour and 1 box instant banana pudding mix (4 servings).
5. Crack in 4 eggs.
6. Pour in 1/2 cup vegetable oil and 1/2 cup water.
7. Add 3/4 teaspoon ground cinnamon and 1 teaspoon banana extract.
8. Using an electric mixer, blend all the ingredients together on medium speed until the batter is smooth and homogeneous, about 3 to 4 minutes. Scrape down the bowl once or twice so no dry pockets remain.
9. Fold in 1 cup chopped walnuts by hand just until distributed evenly through the batter.
10. Spoon or scoop the batter into the prepared muffin cups, filling each about 3/4 full. This gives room for the muffins to rise without overflowing.
11. Bake in the preheated 350°F oven for about 20 minutes. Test doneness by inserting a toothpick into the center of a muffin; it should come out clean or with a few moist crumbs but no wet batter.
12. Remove the pan from the oven and let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely or serve warm.
13. Store cooled muffins in an airtight container at room temperature for up to 3 days, or refrigerate for longer storage. For best texture, reheat briefly before serving.

Why You’ll Keep Making It

These muffins combine convenience and true banana flavor. The boxed mix and instant pudding keep things fast, but ripe bananas and walnuts deliver a homemade texture and taste that aren’t overly processed. They freeze well, travel easily, and please a crowd—great for school mornings, potlucks, or just a reassuring batch in the freezer for busy days.

The recipe tolerates slight tweaks (extra nuts, streusel, or chocolate chips), yet the core produces consistent, moist muffins every time. If you like banana bread but want individually portioned servings, this is a go-to.

If You’re Out Of…

• Banana extract — Omit it; the mashed bananas and pudding still provide solid banana flavor. Use a drop of vanilla if you want another boost.
• Instant banana pudding — You can skip it, but the texture may be slightly less tender and the banana flavor less concentrated.
• Walnuts — Swap for pecans or sunflower seeds, or omit for nut-free muffins. If using pecans, roughly chop to match the texture.
• Vegetable oil — Use neutral oil like canola or melted unsalted butter for a richer flavor (same amount).

Gear Checklist

• Standard 12-cup muffin pan (or two smaller pans)
• Paper liners or nonstick spray
• Large mixing bowl
• Electric mixer (hand or stand) — required by the source directions for 3–4 minutes of blending
• Measuring cups and spoons
• Rubber spatula for scraping
• Scoop or spoon for portioning batter
• Wire cooling rack

Things That Go Wrong

Batter too thin or muffins collapse

If your batter seems unusually runny, check that you measured the dry mix and liquids correctly. Overmixing after adding flour can also weaken structure—mix until smooth but don’t keep beating beyond the instructed 3–4 minutes. Make sure your oven is at the correct temperature; an oven thermometer helps.

Muffins too dense

Dense muffins usually come from under-ripe bananas, over-packed measuring cups, or not enough mixing to distribute the leavening from the cake mix. Use ripe bananas and mix until smooth as directed.

Tops crack or are uneven

Some cracking is normal with muffin tops, but very uneven rise can come from uneven oven heat or overfilling the cups. Fill to 3/4 full and rotate the pan midway through baking if your oven has hot spots.

Seasonal Flavor Boosts

• Fall: Add 1/2 teaspoon pumpkin pie spice in place of cinnamon and fold in 1/2 cup dried cranberries for a fall twist.
• Winter: Stir in 1/2 cup chopped dark chocolate or chocolate chips for a richer treat.
• Spring: Fold in 1/3 cup fresh blueberries for a lighter, fruit-forward muffin (toss berries in a teaspoon of flour first to prevent sinking).
• Summer: Replace walnuts with toasted coconut flakes and add a squeeze of fresh lime zest for a tropical edge.

Method to the Madness

This recipe leans on a box mix and instant pudding to simplify mixing and ensure consistent results. The electric mixer recommendation is there to evenly hydrate the dry mix and fully incorporate the mashed bananas and oil so the batter finishes silky and lump-free. Folding the walnuts in at the end prevents them from breaking down and keeps texture contrast.

Filling the cups three-quarters full gives the muffins room to dome without spilling. A 20-minute bake time is a guideline—ovens vary—so always use a toothpick test to confirm doneness.

Save It for Later

To freeze: cool muffins completely, then place them in a single layer on a baking sheet and freeze until solid (about 1 hour). Transfer to a freezer-safe bag or container for up to 3 months. Thaw at room temperature or warm in a 300°F oven for 8–10 minutes.

To reheat single muffins quickly, microwave for 15–20 seconds or warm in a toaster oven set to 325°F for 5–7 minutes. This restores a fresh-baked texture.

FAQ

• Can I make mini muffins? Yes. Reduce bake time to about 10–12 minutes and watch closely for a clean toothpick test.
• Can I use frozen bananas? Thaw and drain any excess liquid, then mash before measuring 1 cup. Too much added liquid will affect texture.
• Do I need to grease the pan if I use liners? No, paper liners are sufficient. For direct pan use, grease well or use nonstick spray.
• Can I halve the recipe? Yes. Use a smaller bowl and adjust bake time slightly; check earlier for doneness.
• Why add extra flour? The 2 tablespoons help absorb extra moisture from bananas and pudding mix so the muffins hold their shape.
