Ingredients
- Ground cinnamon: Cinnamon adds warmth to the muffin batter and the streusel topping.
- Ground cardamom: Cardamom is optional, but it adds a subtle, cozy, bakery-style flavor that pairs beautifully with banana.
- Ripe bananas: Ripe bananas add sweetness, moisture, and classic banana muffin flavor. The browner and softer the bananas are, the more flavor they will bring to the muffins.
- Blackberries: Fresh or frozen blackberries both work well. They add juicy, tart-sweet pockets throughout the muffins.
See recipe card for quantities.
Hint: Don't over-mix your batter! This will impact the final rise in the oven and can lead to dense, flat muffins.
Easy Substitutions & Variations
- Butter: Use a good-quality dairy-free butter if you want to make these without dairy butter.
- Milk: Use whole milk, 2% milk, or a full-fat nondairy milk like oat milk.
- Mixed berries: Use a mix of blackberries, blueberries, and raspberries for a colorful berry muffin.
- Lemon: Add 1 tablespoon of lemon zest to the batter for a brighter flavor. If you add lemon, you can leave out the cinnamon for a fresher, fruitier version.
- Nuts: Fold in chopped walnuts or pecans for a nutty banana blackberry muffin with extra texture.
- Sourdough discard: Sourdough discard: If you have an active starter, you can adapt your favorite sourdough discard banana muffins recipe by folding in fresh blackberries right before baking.
- Pumpkin Twist: For a warm autumn variation, you can also look at how I blend fruits in my pumpkin banana bread muffins to get a similarly tender crumb.
How to Make Blackberry Banana Muffins
Note: I bake by weight for accuracy. Cup measurements are approximate and may vary depending on how you scoop.
Step 1: Preheat your oven to 425F. In a small bowl mix wet ingredients until combined. In a separate bowl mix dry ingredients.
Combine wet and dry ingredients and mix until just combined (do not over mix)
Add milk (if needed) 1 tablespoon at a time until you reach this consistency. You might need more or less milk depending on how ripe your bananas are.
Step 2: Coat the blackberries (I used frozen) with 1-2 tablespoons of flour until they are just coated. This prevents them from sinking during baking.
Step 3: Divide the batter between 12 muffin liners. I used two muffin pans in order to let the muffins spread without hitting each other. I use a three tablespoon cookie scoop to portion out my muffins.
Step 4: Mix together the butter and dry ingredients for the streusel and divide it equally between all of the muffin liners. Use all of the streusel! It looks like a lot but trust me you'll need it all!
Bake for 5 minutes at 425 and then switch to 350 for another 15 minutes or until you can stick a toothpick in it and it comes out with just a few crumbs. Don’t open the oven when you change the temp!
Expert Tips
- Use very ripe bananas. The more ripe your bananas are, the sweeter and more flavorful your muffins will be. Spotty, soft bananas are best for baking.
- Do not overmix the batter. Overmixing can make the muffins dense or flat. Mix just until the flour disappears, then gently fold in the berries.
- Add the milk slowly. Banana moisture can vary a lot, so start with 2 tablespoons of milk and add more only if the batter feels too thick.
- Toss the berries in flour. A light coating of flour helps suspend the berries in the batter so they do not all sink to the bottom.
- Use a high initial bake temperature. Starting the muffins at 425°F gives them a strong rise, then lowering the oven temperature helps them bake through without drying out.
What Makes This Recipe Special?
These banana blackberry muffins feel like a cozy banana muffin and a bright berry muffin all in one. The banana keeps the crumb soft and tender, while the blackberries add little pockets of jammy fruit throughout each bite.
The cinnamon streusel and vanilla glaze make them feel bakery-style without making the recipe complicated. It’s a simple muffin batter, but the topping and glaze make the final result feel extra special.
If you love the combination of sweet fruit and warm spices but want something more decadent than a muffin, try making a batch of banana cinnamon rolls instead! If you prefer a banana bread loaf, definitely check out my chocolate chunk banana bread!
Banana Blackberry Muffins FAQs
Yes, frozen blackberries work well in this recipe. Do not thaw them before adding them to the batter, and toss them in flour before folding them in.
Yes, the muffins are still delicious without the glaze. The streusel gives them plenty of sweetness and texture on its own.
The high heat helps the muffins rise quickly and creates a taller bakery-style muffin top. After 5 minutes, the temperature is lowered so the centers can finish baking.
Yes, but the streusel is crispest the day the muffins are baked. They will still taste delicious the next day, but the topping will soften.
Yes, the cardamom is optional. You can leave it out and still have a delicious banana blackberry muffin
Banana Blackberry Muffins Troubleshooting Guide
| Problem | Possible Cause | How to Fix It |
|---|---|---|
| Muffins are dense | Batter was overmixed | Mix only until the flour is incorporated |
| Muffins are flat | Oven was not hot enough or batter was overmixed | Preheat fully and start baking at 425°F |
| Blackberries sank | Berries were not coated in flour | Toss berries with 1–2 tablespoons of flour before folding in |
| Muffins are dry | They were overbaked | Pull them when a toothpick comes out with a few moist crumbs |
| Streusel melted too much | Butter was too hot or streusel was too wet | Let melted butter cool slightly and mix until crumbly |
| Glaze is too thin | Too much milk was added | Add more powdered sugar until thickened |
Storage
Store leftover muffins in an airtight container at room temperature for 3–5 days. The streusel will soften after the first day, but the muffins will still be soft and flavorful.
To freeze, wrap the muffins tightly in plastic wrap and place them in an airtight freezer-safe container or bag. Freeze for up to 3 months. Thaw in the refrigerator or at room temperature before serving.
For the best texture, enjoy these muffins the day they are baked, especially if you want the streusel to stay crisp.
