Easy, Delicious Blueberry Muffins with Greek yogurt

I used 1 t vanilla since the recipe didn't specify... I think that was too much. Tasted somewhat like a cookie, and not light and fluffy. Dense. My baking powder was expired, so that may have been part of it, but I don't think I'll make again. Turned sour after about 4 or 5 days sitting at room temp, so may need to be kept in the fridge.

I substituted peaches for blueberries bc they’re in season!

I used whole wheat all purpose flour and did not add the course sugar to the top. These are now the family favourite for blueberry muffins.

I put 2 heaped tablespoon of batter into the muffin tin holes.
