Whisk together:
  • 2 cups all-purpose flour (284 g)
  • 1 cup old-fashioned oats (96 g)
  • ¾ cup granulated sugar (153 g)
  • 1 teaspoon baking powder (5 g)
  • ½ teaspoon cinnamon
  • ½ teaspoon salt (3 g)
Cut in:
  • 1 cup butter (236 g)
Stir in:
  • 2 egg yolks
Then mix in:
  • 1 tablespoon cold water (15 g)
  • 1 cup fresh blueberries (137 g)
  1. Preheat oven to 375°F. Spray with non-stick baking spray either a 9” x 13” or 8” x 11” or any similar size rectangular baking dish.
  2. Whisk together flour, oats, granulated sugar, baking powder, cinnamon and salt. If using a food processor, just give the dry ingredients a few quick pulses to blend.
  3. Slice the butter in cubes. Cut the butter into the dry ingredients using a pastry blender or two knives. If using a food processor just pulse until butter is distributed all throughout. Mixture should look like coarse crumbs.
  4. Mix in egg yolks using a spatula until well blended. Pulse if using a food processor.
  5. Stir in cold water (or pulse if using a food processor). Dough will still look crumbly, but if you take a handful and clench it in your hand, it should stick.
  6. Press the dough onto the baking dish reserving about ¼ or 1/3 for the crumb topping.
  7. Spread a single even layer of blueberries on the dough.
  8. Scatter the remaining dough in clumps filling in the gaps between the blueberries.
  9. Bake for 30 - 35 minutes or until golden brown. Remove from oven and let cool before slicing into bars. Store in an airtight container either chilled or at room temperature; I prefer them cold out of the fridge.
