Lightly spoon 1 cup flour into a dry measuring cup; level with a knife. Combine 1 cup flour and the next 4 ingredients (1 cup flour through baking soda), stirring well with a whisk. Place the granulated sugar and butter in a large bowl, and beat with a mixer at medium speed until well blended (about 2 minutes). Add egg and lemon rind; beat until well blended. Add flour mixture and buttermilk alternately to sugar mixture, beginning and ending with the flour mixture. Toss blueberries with 1 tablespoon flour, and fold into batter.
Spoon the batter into 24 miniature muffin cups coated with cooking spray. Bake at 350° for 14 minutes or until the cakes spring back when touched lightly in center. Combine powdered sugar and juice, and drizzle over warm cakes.
These are always a hit everyone always asks for the recipe. I put the blueberries in after after the batter ensuring they each have 3, silly I know. I do not add the lemon and sugar on top they are plenty sweet without. I always make them as mini muffins.
A great treat for a morning meeting or to take for a Holiday gift for a group. And they are quick so easy to bake the same morning. I make them exactly as written except for adding the blueberries at the end.
I need to retract an earlier review, as I added a pint of berries rather than the specified 1/2 cup. No wonder they were soggy! I must have been thinking of other recipes and automatically added the whole pint. The flavor was great so I will try them again. I will also try the stated lemon vs. lime.
