Make irresistible, moist jumbo buttermilk blueberry muffins packed with juicy wild blueberries just like you get at your favorite bakeries and coffee shops.
Preheat and Prep: Preheat your oven to 400°F. Line a jumbo muffin pan with cupcake liners or grease with butter.
Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
Combine Wet Ingredients: In another bowl (or in the bowl of a stand mixer), cream the softened butter and sugar together. Add in eggs, buttermilk, and sour cream. Mix until well combined.
Combine: Gradually add the dry ingredients in two parts (leave a few tablespoons of the flour mixture aside to coat your blueberries), gently mixing until just combined. Do not overmix. Add blueberries to the leftover flour mixture. This step is optional, but it ensures that the blueberries don't sink to the bottom.
Add Blueberries: Fold in the blueberries into your batter gently to avoid breaking them and turning the batter blue. It will be thick, not runny.
Fill the Muffin Tin: Divide the batter evenly, filling each cavity to the brim. Top with coarse sugar (turbinado sugar)
Bake: Bake at 400°F for 5 minutes, and then lower the heat to 325°F for 20-25 minutes or until a toothpick inserted into the center comes out clean.
Cool: Allow the muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
