They turned out even better than I expected — soft, tender, naturally sweet, and filling. They might just be my favorite muffin creation yet.

How are these muffins healthy?
These muffins are not only tasty but also nutritious:
- Nutrient-rich ingredients: Oats, bananas, and blackberries provide fiber, vitamins, minerals, and antioxidants. Oats supply soluble fiber and minerals, bananas add potassium and vitamin B6, and blackberries contribute antioxidants and vitamin C.
- Naturally sweetened: Ripe bananas provide the sweetness so you can skip refined sugars and still enjoy sweet muffins.
- Low in added fats: These muffins rely on mashed bananas for moisture and binding, minimizing or eliminating the need for added oil or butter.
- High in fiber: With oats and blackberries, the muffins deliver satisfying fiber that supports digestion and helps you feel full longer.
Ingredients and substitutions
Below are the ingredients used in these Banana Blackberry Muffins. Exact measurements are in the recipe card further down the page.
Oats: Blend rolled oats into a fine flour for the best texture, or use store-bought oat flour.
Ripe bananas: They sweeten, moisten, and bind the batter. Choose bananas with brown spots for maximum flavor.
Baking powder: Provides lift so the muffins stay light and tender.
Water: A small amount balances moisture; you can substitute plant milk for extra protein and creaminess if you prefer.
Blackberries: Fresh is preferred, but frozen works too — frozen berries may add extra moisture, so bake accordingly.
Optional extras: Vanilla extract, a pinch of salt, coconut sugar, or whole oats for topping all work well if you want to boost flavor or appearance.
Equipment needed
- Digital food scale (recommended for accuracy).
- Blender or food processor to grind oats into oat flour (skip if using oat flour).
- Silicone or non-stick muffin tray to prevent sticking.
- Mixing bowl and spatula for combining ingredients.
- Fork or plate for mashing bananas.
How to make Banana Blackberry Muffins
Here’s a clear summary of the process. For step-by-step photos and the recipe card, see the section labeled “recipe” below.
Step 1: Preheat the oven to 350°F (175°C). Grease a muffin tin lightly, use silicone cups, or line with paper liners. This recipe yields six large muffins or eight smaller ones.
Step 2: If making oat flour, blend oats until very fine. Sift if you want an extra-smooth texture.
Step 3: Combine the oat flour and baking powder in a bowl. Add a pinch of salt if using.
Step 4: Mash the bananas thoroughly with a fork until smooth so the batter isn’t dry.
Step 5: Add the mashed bananas and water (and vanilla if using) to the dry ingredients and fold gently to combine.
Step 6: Fold in the blackberries carefully to avoid crushing them too much.
Step 7: Divide the batter evenly among 6 or 8 muffin cavities. Top with a sprinkle of coconut sugar or whole oats if desired.
Step 8: Bake for 22–30 minutes: about 22 minutes for smaller muffins and around 30 minutes for larger ones. A toothpick should come out with a few moist crumbs. Avoid overbaking to keep the muffins tender. Cool in the tin for 10 minutes before removing.
Tips and notes
Use ripe bananas: Bananas with brown spots give the best flavor and sweetness and mash easily.
Customize freely: Swap blackberries for blueberries or raspberries, add nuts or seeds for crunch, or include vanilla and a pinch of salt to enhance flavor.
Blend oats finely: A smooth oat flour prevents graininess; sift if needed for an even softer texture.
Avoid overmixing: Fold ingredients until just combined to keep the muffins light and tender.
Adjust baking time: Oven temperatures and muffin sizes vary, so check near the end of the baking time and remove when a toothpick shows a few moist crumbs.
Cool before removing: Let muffins rest in the tin for 10 minutes to set and make removal easier.
Serve fresh or reheat: Enjoy at room temperature or warm briefly in the microwave or oven for a fresh-baked feel.
How to store Banana Blackberry Muffins
Room temperature: Keep muffins in an airtight container for up to 3 days.
Refrigeration: Store in a sealed container for up to one week to prolong freshness.
Freezing: Wrap each muffin individually or place in a freezer bag for up to 3 months. Thaw overnight in the fridge or warm briefly in the microwave.
Reheating: Microwave for a few seconds or warm in a 300°F (150°C) oven for 5–10 minutes for a refreshed texture.
FAQ
Can I use frozen blackberries instead of fresh ones?
Yes. Frozen blackberries work fine, but they can release more moisture during baking and slightly change the muffin texture. You don’t need to thaw them first.
Can I substitute oats with oat flour?
Yes. Use an equal amount of store-bought oat flour and skip the blending step.
How can I make these muffins gluten-free?
To ensure they’re gluten-free, use certified gluten-free oats and baking powder, as cross-contamination can occur in some processing facilities.
Can I add nuts or seeds for extra crunch?
Yes. Fold in chopped nuts like walnuts or pecans, or seeds such as pumpkin or sunflower seeds, along with the blackberries before baking.
Are these muffins suitable for meal prepping?
Yes. Bake a batch at the start of the week and store them in an airtight container for quick breakfasts or snacks.
Can I omit the blackberries or use a different fruit?
Yes. Substitute with blueberries, raspberries, diced strawberries, or omit the fruit altogether for plain banana oat muffins.
Are these muffins vegan?
Yes. The recipe contains no animal products and is suitable for vegan diets.
