Source: Cook's Illustrated


 5 tablespoons (2 1/2 ounces or 71 grams) unsalted butter , softened
1/2 cup (3 1/2 ounces or 100 grams) sugar
1 large egg
3/4 cup sour cream or plain yogurt
1/2 teaspoon grated lemon zest
1 1/2 cups (6 3/4 ounces or 191 grams) all-purpose flour
1 1/2 teaspoon (7 grams or 1/4 ounce) baking powder
1/4 teaspoon (1 gram) baking soda
1/4 teaspoon (2 grams) salt
3/4 cup (3 3/4 ounces or 105 grams) blueberries, fresh or frozen


2 tbsp butter
1/2 tsp cinnamon powder
3 tbsp flour

Mix all till coarse and sprinkle on top of the muffins before baking.


  • Preheat oven to 375°F. Line a muffin tin with 10 paper liners or spray each cup with a nonstick spray. Beat butter and sugar with an electric mixer until light and fluffy. Add egg and beat well, then yogurt and zest. Put flour, baking powder, baking soda and salt into a sifter and sift half of dry ingredients over batter. Mix until combined. Sift remaining dry ingredients into batter and mix just until the flour disappears. Gently fold in your blueberries. The dough will be quite thick, closer to a cookie dough. Fill them about 3/4 full.  Bake for 25 to 30 minutes, until tops are golden and a tester inserted into the center of muffins comes out clean . Best eaten on same day.
