Banana Nut Muffins made with cake mix have been my go-to recipe for bringing together the comforting flavors of ripe bananas and crunchy walnuts without spending much time or fuss. By using a boxed cake mix, you get a bakery-style texture, but with homemade warmth and freshness in each bite. These muffins are perfect for busy mornings, easy snacks, or even a sweet treat after dinner.
I first made these after spotting a box of butter pecan cake mix in my pantry. Now my neighbor asks for a batch every time we are planning a coffee get-together.
Ingredients
- Butter pecan cake mix: gives the muffins a depth of buttery nut flavor Choose a trusted brand for rich taste
- All-purpose flour: ensures the muffins hold their structure Pick a name brand for consistent results
- Baking powder: provides a fluffy rise Always check freshness for best lift
- Large ripe bananas: are key for sweetness and aroma Look for skins with brown spots but not mushy insides
- Large eggs: bind the batter together and create tenderness Let them come close to room temp for easy mixing
- Walnuts: add crunch and rich nutty undertones Choose fresh unsalted walnuts and chop just before adding
Step-by-Step Instructions
- Preheat and Prep:
- Set your oven to three hundred fifty degrees Fahrenheit Prepare two muffin tins with cooking spray or line with cupcake wrappers Make sure every cavity is lightly coated to prevent sticking
- Mix Dry Ingredients:
- Whisk the cake mix all-purpose flour and baking powder together in a large mixing bowl Stir thoroughly for even distribution as you want every bite to have lift and stability
- Combine Wet Ingredients:
- Mash ripe bananas using a fork or potato masher You want a soft consistency but a few small lumps are fine Crack the eggs into the bowl with the bananas Stir until just combined then fold this mixture into the dry ingredients
- Add Nuts and Fold:
- Chop one cup of walnuts and gently stir them into the batter Use a spatula to fold without overmixing which helps keep the muffins tender
- Portion Batter:
- Scoop the batter into muffin tins filling each cavity two thirds full This keeps the muffins baking evenly and prevents overflow
- Top and Bake:
- Sprinkle the remaining half cup of chopped walnuts evenly over the tops Place the trays in the center of the oven and bake for seventeen to twenty minutes Watch for golden brown tops and check doneness with a toothpick inserted in the center which should come out clean
- Cool and Serve:
- Let muffins rest five minutes before lifting gently from the tins Enjoy warm or move to a rack until fully cooled

Walnuts are my favorite part as they toast up perfectly in the oven adding a subtle crunch My kids love helping sprinkle the nuts on top and always compete to see who can get the muffin with the most
Storage Tips
Store muffins at room temperature for three to five days Lightly drape with a clean kitchen towel instead of sealing tightly to prevent sogginess If you plan to keep them longer wrap individually and freeze bringing them to room temp or lightly microwaving before eating
Ingredient Substitutions
If you cannot locate butter pecan cake mix a plain yellow or white cake mix will do in a pinch This version will have a lighter flavor but still be delicious You can also try swapping in pecans or almonds for walnuts or leaving out nuts altogether for a smooth banana-only muffin

Serving Suggestions
