Ingredients
  

Crust and Topping
  • 2 cups all purpose flour
  • 1 cup quick oats
  • 1.5 cups sugar for the topping
  • 1/4 teaspoon salt
  • 1.5 cups unsalted butter, chilled cut into 1/2 inch cubes
  • 3/4 cup flour reserved from the crust mixture
Filling
  • 4 large eggs
  • 2 cups sugar for the filling
  • 1 cup sour cream
  • pinch salt
  • 1 teaspoon vanilla extract
  • 2 packages (16 oz) frozen mixed berries (strawberries, blackberries, blueberries)

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C) and grease a 9x13 inch baking pan.
  2. Put oats into the food processor and pulse until a coarse flour forms.
  3. Add all-purpose flour, 1.5 cups of sugar, and 1/4 teaspoon of salt to the food processor and pulse a few times to mix.
  4. Cut the chilled butter into 1/2 inch cubes and add to the flour mixture.
  5. Process until the butter is evenly distributed but the mixture is still crumbly, about 30 to 60 seconds.
  6. Reserve 1.5 cups of the mixture to use as the topping.
  7. Press the remaining mixture into the bottom of the pan to form the crust.
Baking
  1. Bake the crust for 12 to 15 minutes.
  2. Cool the crust for at least 10 minutes.
  3. Whisk the eggs in a large bowl.
  4. Add 2 cups of sugar, sour cream, 3/4 cup flour, a pinch of salt, lemon zest, and vanilla extract to the eggs and whisk to combine.
  5. Gently fold the frozen mixed berries into the filling mixture.
  6. Spoon the berry filling over the cooled crust.
  7. Sprinkle the reserved flour-oat mixture evenly over the filling.
  8. Bake the bars for 45 to 55 minutes until set.
  9. Cool the bars for at least 1 hour before cutting into bars.

Notes

Serve the bars warm or at room temperature. Add a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence. Store cooled bars in an airtight container in the refrigerator for up to 4 days or freeze for longer storage.
