Ingredients
- 1 stick (113 grams) unsalted butter
- 2 cups (254 grams) all-purpose flour
- 1/2 cup (100 grams) light brown sugar
- 1/4 cup (50 grams) granulated sugar
- ½ teaspoon fine sea salt
- 1 tablespoon baking powder
- 3/4 cup (178 grams) buttermilk*, (at room temperature)
- 1 large egg, (at room temperature)
- 1 teaspoon vanilla extract
- 1 1/2 cups (210 grams) blueberries, (fresh or frozen (don't thaw first))
- 1/4 cup (50 grams) granulated sugar
- 3 tablespoons (24 grams) all-purpose flour
- 1/2 teaspoon ground cinnamon
- 2 tablespoons (29 grams) unsalted butter, (melted)

Instructions
1. Preheat the oven to 400°F. Line a standard muffin tin with paper liners.
2. [Brown the butter:] In a small stainless steel skillet set over medium heat, melt the butter. Swirling the pan occasionally, continue to cook the butter. It should become foamy with audible cracking and popping noises.
3. [Brown the butter:] Once the crackling stops, continue to swirl the pan until the butter develops a nutty aroma and brown bits start to form at the bottom. Once the bits are amber in color, about 2 to 3 minutes after the popping stops, remove from heat and pour into a medium mixing bowl, being sure to get all the toasted bits on the bottom. Set aside to cool.
4. [Make the crumb topping:] While the brown butter cools, combine all the topping ingredients in a small bowl. Mix with a fork until the texture resembles wet sand.
5. [Make the batter:] In a large bowl, whisk together the flour, sugars, salt, and baking powder.
6. [Make the batter:] In a medium bowl, whisk together the cooled browned butter, buttermilk, egg, and vanilla. Pour into the dry ingredients and stir with a rubber spatula until just combined. Gently stir in the blueberries. Do not overmix. Batter will be thick. Divide evenly among the muffin tin cups.
7. [Make the batter:] Use your fingertips to sprinkle the crumb topping over the muffin batter in pans. Bake until golden brown and a toothpick inserted in the center comes out clean, about 20 to 22 minutes. Transfer the pan to a wire rack to cool for 5 minutes before removing the muffins to the rack to cool completely.
8. [Make the batter:] Serve or store in an airtight at room temperature for 3 days. Reheat in the microwave for about 15 seconds if desired. Muffins can also be frozen in an airtight container for up to 3 months.
