Ingredients
Crumb Topping
- 1/2 cup all-purpose flour (72g)
- 1/2 cup sugar (112g)
- 1/2 tsp ground cinnamon
- 1/4 cup butter, melted (salted or unsalted)
Muffin Batter
- 1.5 cups all-purpose flour (212g)
- 3/4 cup granulated sugar
- 2 tsp baking powder
- 1/4 tsp kosher salt
- Zest of 2 Meyer lemons (or zest of 1 orange plus zest of 1 lemon)
- 1/3 cup unsalted butter, melted (about 5.33 tbsp)
- 1 large egg
- 2/3 cup buttermilk
- 2 cups blueberries (frozen works fine)
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners to prepare for baking.
- Make Crumb Topping: In a small bowl, whisk together flour, sugar, and cinnamon. Pour in melted butter and mix with a fork until crumbs form. Chill this crumb topping mixture in the refrigerator while you prepare the batter.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, salt, and citrus zest until well combined.
- Mix Wet Ingredients: In another large bowl, whisk the melted butter, egg, and buttermilk together. It’s okay if this mixture looks slightly curdled or lumpy.
- Combine Wet and Dry Ingredients: Pour the wet ingredients into the dry ingredients and stir gently just until the batter comes together. It will be thick and lumpy; avoid overmixing to keep your muffins tender.
- Add Blueberries: Gently fold the blueberries into the batter, distributing them somewhat evenly without stirring too vigorously, to prevent the batter from turning purple.
- Fill Muffin Cups: Using a large 3-Tbsp cookie scoop, evenly portion slightly overfilled scoops of batter into the 12 lined muffin wells.
- Add Crumb Topping: Remove the crumb topping from the fridge, break it up with your fingertips, and sprinkle it evenly over each muffin batter portion.
- Bake Muffins: Bake for 28-30 minutes, or until the crumb topping is golden brown and the muffins spring back when gently pressed in the center.
- Cool and Serve: Allow muffins to cool for about 2 hours to enhance the flavor and texture, though they can be enjoyed warm right out of the oven.
Notes
- You can use either salted or unsalted butter for the crumb topping according to your preference.
- Frozen blueberries work well and prevent the batter from turning too purple, but fresh can be used if preferred.
- Do not overmix the batter to avoid tough muffins; lumps are perfectly fine.
- Letting the muffins cool enhances their flavor and crumb texture.
- Use Meyer lemons for a sweeter, more fragrant citrus flavor, or substitute with a combination of orange and lemon zest.
