For an extra touch of flavor, try adding a pinch of lemon zest to the batter. If you don't have sour cream, you can substitute plain Greek yogurt. Gently toss the blackberries with a tablespoon of flour before folding them into the batter to prevent them from sinking to the bottom of the muffins. These muffins are best enjoyed fresh, but they can be stored in an airtight container at room temperature for up to 2 days.

Oct 4, 2024My blackberries were a little tart, so I added a bit more sugar. They turned out perfectly!
