Ingredients
Method
- Rub the cold butter into the crumble topping ingredients with your fingertips until the mixture resembles wet sand. Refrigerate while you prepare the batter.
- Preheat oven to 400°F (200°C) and line a 12-cup muffin tin. In a large bowl, whisk together the flour, baking powder, salt, and sugar.
- In a separate bowl, stir the buttermilk, oil, egg, and vanilla until smooth. Pour into the dry ingredients and fold with a spatula just until no dry streaks remain.
- Gently fold in the blueberries with 3 to 4 strokes.
- Divide the batter among the muffin cups, filling each to the top. Pinch the cold crumble over the muffins without pressing it down.
- Bake 18 to 22 minutes until golden and a toothpick comes out clean. Cool in the pan for 5 minutes, then lift out and serve warm.
Notes
No buttermilk? Stir 1 tablespoon lemon juice or white vinegar into 1 cup milk and let it sit for 5 minutes. The muffins are best the day they’re baked, but they stay moist for a couple of days at room temperature.
