    About This Recipe

    Next time you need to bribe your way into a good apartment, make up a basket of these mini blueberry crumb muffins. You’re sure to win if you do – people simply go nuts for them!

    Made with a sour cream coffee cake-esque batter and topped with a delightfully crispy brown sugar crumble, these tasty little fellas are sure to win hearts and minds. What’s not to love?

    They’re sweet without being cloying, and since they’re called “muffins” instead of “cupcakes,” they are well within social norms to eat as a meal. (Not that social norms could stop me from eating cookies for breakfast. Just sayin’.)

    Aside from being totally delicious, my blueberry mini muffins are also super customizable. Feel free to swap out the blueberries for something else like other berries, dried fruit, mini chocolate chips, chopped nuts, or anything else that tickles your fancy.

    Finally, these amazingly tasty crumb-topped blueberry mini muffins are made using simple, easy-to-find ingredients. That’s to say, there’s nothing standing in your way of morning bliss!

    Ingredients

    My mini blueberry muffin recipe with streusel topping are primarily made with pantry staples you can find at your local grocery stores. Here are a few notes to keep in mind before making these sweet muffins for a healthy breakfast: 

    • All-Purpose Flour - Use the scoop and sweep method or purchase on a kitchen scale to make sure these mini muffins stay nice and moist.
    • Brown Sugar - Either light or dark brown sugar will work here. Dark brown sugar will offer more burnt toffee and molasses notes if that appeals to you.
    • Cinnamon & Nutmeg - These two warming spices pack a mighty flavor punch. Feel free to experiment with other spices if you like – cardamom and ginger also play nicely with blueberries.
    • Eggs - If eggs are a no-no for you, feel free to swap in flax eggs in their place. (1 flax egg = 1 tablespoon Flax Seed + 3 tablespoon Water + 5 minutes rest time)
    • Neutral Oil - Any neutral oil will do the trick. Grapeseed, avocado, vegetable oil, canola, corn or peanut oil all fit the bill.
    • Vanilla Extract - Feel free to use vanilla paste or powder instead, depending on what you have in your cupboard. Other options include almond or lemon extract or almond extract, depending on the flavor you’re going for. 
    • Sour Cream - Sour cream adds a ton of moisture. You can easily swap in full-fat Greek yogurt instead, or opt for any plant-based alternatives.
    • Juicy Blueberries - You can also substitute in your favorite muffin mix-in like other berries, nuts, or mini chocolate chips.

    Equipment

    You don’t need much to make these mini blueberry muffins. Here are the pieces of equipment you might need to get:

    • Mini Muffin Tin & Liners - I don’t know why I like mini muffins just as much as regular muffins, but I do. Feel free to use regular-sized muffin tins instead instead of miniature muffin tins, so long as you increase the bake time as needed.
    • Mesh Strainer  - I absolutely adore using my mesh strainer - it can also help with straining ricotta, dusting desserts with powdered sugar, or act as a colander.
    • Small Cookie Scoop - You can easily get away with using a spoon to put the batter into the muffin tins, but I find that cookie scoops do the job better and with less mess.

    How to Make Mini Blueberry Muffins

    These miraculously easy blueberry muffins are easy like Sunday morning. Here’s how to make them: 

    Prep: Preheat the oven to 350 degrees Fahrenheit and line a mini muffin pan with muffin liners. 

    Make crumble: Mix all ingredients together until well combined, then place in the refrigerator for 10 minutes so it firms up a bit in a separate bowl or freezer bag. Once firm, break the crumble into small pieces and proceed as directed below. 

    Mix dry ingredients: Sift the flour, baking powder, baking soda and salt together in a medium-sized bowl and whisking to combine. 

    Mix wet ingredients: In a separate large bowl, whisk together the eggs, brown sugar, avocado oil, vanilla extract and sour cream until well combined. 

    Make batter: Pour the dry ingredients into the wet ingredients and gently fold together until smooth, making sure not to overmix.

    Add berries: Fold in the juicy fresh blueberries until combined. 

    Scoop, sprinkle, and bake: Scoop the blueberry muffin batter into the mini muffin cups until ⅔ of the way full. Sprinkle with chilled crumble before baking for 14-17 minutes.

    Expert Tips

    1. Make your crumble first. This allows it plenty of time to firm up in the fridge so you get real, sizeable chunks instead of a sandy topping.
    2. Only fill ⅔ full. There’s a temptation to get as much flavor as possible into each bite-sized muffin, I know. But do yourself a solid and only fill the tins up to the ⅔ mark, or you’ll risk making quite the mess.
    3. Treat yourself! Mini blueberry muffins are extra special because you get to eat several before it’s considered a serving. Go on and reach for that second. And maybe third. To your heart's content!

    Frequently Asked Questions

    Can I use frozen blueberries?

    You can certainly try, but I wouldn't advise it! Note that their color may bleed a bit more than their fresh counterparts, and as they thaw the added moisture may affect the end result of the muffin.

    How do I keep my blueberries from sinking to the bottom of the muffin?

    One of the things I love best about mini muffins is that they are nice and compact, giving them a bit of extra structure. If you are making full-sized muffins, however, I suggest tossing the berries in a bit of flour or cornstarch before adding to the batter; the minuscule grains will help the berries stay afloat.

    Can I make these mini blueberry muffins ahead of time?

    Yep! They should stay well in an airtight container in the fridge for 3-4 days. You can also freeze them for up to a month.
