About allergens

These Blueberry Brown Butter Muffins are soft, rich, and packed with juicy bursts of blueberries in every bite. The secret ingredient is homemade brown butter, which adds a deep, nutty aroma and gives the muffins a warm, caramel-like flavor that pairs perfectly with the sweetness of the berries.

To keep the blueberries evenly distributed, they’re lightly dusted with flour before mixing in the batter ensuring they don’t sink to the bottom. The batter itself is tender and moist, thanks to sour cream and just the right balance of ingredients.

Each muffin is topped with a crunchy pecan streusel made with cinnamon and butter, adding texture and a slightly toasted finish that makes these feel extra special. Baked until golden at 180°C (350°F), they come out soft inside with a beautifully crisp topping.

Perfect for breakfast, brunch, or an afternoon coffee break, these muffins are best enjoyed slightly warm, when the brown butter aroma is at its peak and the blueberries are perfectly juicy.

Pro Tips for Perfect Muffins

  • Don’t skip browning the butter. This step adds deep flavor and makes these muffins stand out from classic blueberry muffins.

  • Let the brown butter cool slightly. If it’s too hot, it can cook the eggs when added.

  • Don’t overmix the batter. Mix just until combined to keep the muffins soft and tender.

  • Gently press the streusel. Lightly pressing it into the batter prevents it from falling off during and after baking.

  • Use room temperature eggs. They combine more easily and help create a smoother batter.

Common questions

How do I know when butter is properly browned?

Watch for golden-brown specks at the bottom of the pan and a nutty aroma - remove from heat immediately once you see/smell this.

How do I keep blueberries from sinking?

Toss fresh or frozen blueberries in 1 tablespoon of flour before folding them into the batter.

Can I use frozen blueberries?

Yes, do not thaw them first, fold them straight into batter frozen.

Ingredients

Ingredient Substitutes
  • 25 g (1 oz) Erythritol + 20 g (¾ oz) Stevia baking blend + 0 g Pure stevia powder

Instructions

  1. 1

    Prepare the Butter

    From the 175g butter, use 150g to make brown butter and reserve 25g for the streusel.

  2. 2

    Mix the Dry Ingredients

    Cut 150g butter into cubes and place it in a light-colored saucepan over medium heat. Once melted, it will begin to foam and bubble. Stir frequently. After a few minutes, the milk solids at the bottom will turn golden brown and release a nutty aroma. As soon as you see brown specks and smell that toasted fragrance, remove from heat immediately and pour into a mixing bowl. Let it cool slightly.

  3. 3

    Prepare the Dry Ingredients

    From the total 270g flour, reserve 20g for coating the blueberries. The remaining 250g will go into the batter.

    In a bowl, whisk together 250g flour, baking soda, baking powder, and salt.

  4. 4

    Whisk the Brown Butter, Sugar, and Eggs

    Once the brown butter is warm (not hot), add the brown sugar and whisk for about 4 minutes to slightly dissolve the sugar. Add the eggs one at a time, whisking well after each addition to fully incorporate and prevent the eggs from cooking.

  5. 5

    Make the Blueberry Muffin Batter

    Sift in the dry ingredients and mix just until combined. Add sour cream and milk, whisk until combined. Add the blueberries directly into the batter. Sprinkle the reserved 20g flour over the blueberries and gently fold everything together until just combined. This helps prevent the blueberries from sinking during baking.

    Divide the batter into muffin trays, filling each cavity almost to the top.

  6. 6

    Prepare the Pecan Streusel and Bake

    Melt the reserved 25g butter. In a food processor, combine pecans, sugar, cinnamon, and melted butter. Process until the pecans are finely chopped and the mixture resembles coarse crumbs.

    Spoon the streusel generously over each muffin and gently press it into the batter so it stays in place during baking.

    Bake at 180°C (350°F) for about 25 minutes, or until a toothpick inserted in the center comes out clean.

  7. 7

    Cool and Serve

    Allow the muffins to cool for 5–10 minutes before serving. Enjoy them warm for the best texture and flavor, when the blueberries are soft and the brown butter aroma is most noticeable. Perfect with coffee or as a sweet breakfast treat.
