Step‑by‑Step Instructions
- Preheat your oven to 375°F (190°C) and line a cupcake pan with paper liners.
- In a large mixing bowl, combine 1 cup of all-purpose flour, 1 cup of granulated sugar, and 1-2 teaspoons of ground cinnamon. Mix in ½ cup of softened butter until you achieve a crumbly texture.
- Cream together ½ cup of unsalted butter and 1 cup of granulated sugar until light and fluffy, about 2-3 minutes.
- Incorporate 2 large eggs one at a time, mixing well after each addition. Stir in 1 teaspoon of vanilla extract.
- Mix in ½ cup of full-fat sour cream (or Greek yogurt) and ½ cup of whole cultured buttermilk until well combined.
- Whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, and ½ teaspoon of salt in a separate bowl. Gradually add to the wet mixture, stirring until just combined.
- Fold in 1 cup of either fresh or frozen wild blueberries.
- Fill each muffin liner about ¾ full and sprinkle streusel topping over each.
- Bake for 25-30 minutes, or until muffins turn golden brown and a toothpick comes out clean.
- Allow to cool in the pan for about 5 minutes before transferring to a wire rack.
