Gradually add the flour mixture to batter, stirring just until absorbed. Then stir in oats and walnuts. Toss the frozen blueberries in the reserved teaspoon of flour and stir in the blueberries
Carefully shape into balls (mine were a little over an inch) and space about 2 ½ inches apart on the parchment lined cookie sheets.
Bake at 350 degrees for 12-15 minutes (check at 10). Let cool on cookie sheets for about 3 minutes, then transfer to a wire rack to cool.
