I have no other recipes for blueberry muffins. This is it, folks. The recipe I grew up on.

My dear Grandma Renelt’s recipe for Blueberry Muffins with Crumb Topping.

These muffins are tender and moist, and super flavorful with fresh summer blueberries studded throughout. And, as if that wasn’t enough, there’s a crunchy, buttery, sugary crumb topping that totally clinches the win for these muffins.

Friends and family have asked me for this recipe time and time again, and with very good reason.

Enjoy!

My grandma is an incredibly special woman to me. She has always worked hard and played even harder (just try to outlast this woman in cards, dice, or marbles!). And I’m positive that much of my domestic ways were passed directly from her, to my mom, to me.

I found this photo of Grandma in play mode and just had to share.

When I first came across this old photo, I passed on by it, looking for another one I had in mind. Then something was nagging at me to return to it…

Of course!

The cowboy Grandma was getting cozy with bore a striking resemblance to the same one our girls sat by on our trip to the Black Hills.

blueberry picking

I’ve never had better blueberries than the ones we pick locally each July and August. The berries are sweet, tart, and perfectly firm.

And as a bonus, blueberry picking makes for a super fun day trip!

Can you make blueberry muffins with frozen blueberries?

Every single summer, after we pick blueberries, we make a batch of blueberry muffins. The goodness of the just-picked berries is undeniable. A few more favorite blueberry recipes: my mom’s Blueberry Tea Cake, Blueberry Pot Pies, and this beautiful, tangy Roasted Blueberry Crème Fraîche Ice Cream.

But I always make sure to pick enough blueberries to freeze, to ensure a few batches of Grandma’s muffins over the upcoming months.

Yes, this recipe works very well with frozen blueberries. Simply fold the frozen berries into the muffin batter, just like you would the fresh berries.

How to make crumb topping for muffins

My biggest piece of advice for making crispy crumb topping for muffins is to use butter that is just nicely softened at room temperature. Do not melt the butter. And then, with a fork, just keep pressing the dry ingredients into the butter until pea-sized pieces form.

When sprinkling the crumb topping mixture over the muffin batter, use your fingers to compress some of it into larger pieces.

To ensure the crumb topping stays crisp for a day or two, simply store any leftover muffins at room temperature, uncovered. Uncovered is the key.

Grandma Renelt's Blueberry Muffins with Crumb Topping

These blueberry muffins are tender, while the topping is crispy. The recipe comes from my grandma, my favorite blueberry muffins in all the world!
Yield: 10 to 12 muffins
Prep Time: 20 minutes
Cook Time: 20 minutes
Total Time: 40 minutes

Ingredients

for the muffins:

  • 1 large egg
  • 1/2 c. milk
  • 1/4 c. vegetable oil
  • 1-3/4 c. flour
  • 1/2 c. sugar
  • 2 tsp. baking powder
  • 1/2 tsp. kosher salt
  • 1/4 tsp. cinnamon
  • 1-1/2 c. blueberries, fresh or frozen (if frozen, do not thaw)

for the crumb topping:

  • 1/3 c. sugar
  • 1/4 c. flour
  • 2 T. unsalted butter, at room temperature

Instructions

  1. Preheat oven to 400° F. Spray standard muffin tin with non-stick spray, or use baking cup liners, and set aside.
  2. Mix egg, milk, and oil in small bowl. In a large bowl, whisk the flour, sugar, baking powder, salt, and cinnamon. Add wet ingredients to dry ingredients and stir. Do not overmix. Fold in blueberries. Spoon into muffin tin and let rest a few minutes while you prepare the crumble topping. For plumper, fuller muffins, divide batter between just 10 of the muffin cups (as shown in my photos). For smaller muffins, use all 12 cups.
  3. In a small bowl, combine all topping ingredients with a fork, until crumbly. You want some pea-size pieces of crumble. Sprinkle over muffin batter.
  4. Bake until crumb topping is a bit golden and a toothpick comes out just barely clean, about 20 minutes. Let rest in pan for about 5 minutes before removing to a cooling rack to cool. Muffins are best eaten on the day they are made, when the crumb topping is crunchiest. If we don't eat all the muffins in the first day, we leave them out on the counter, uncovered. This will help to keep the crumb topping more crisp.
