Strawberry Filling

  1. Stir strawberries and sugar together in a small saucepan. Set over medium heat and bring to a simmer. Simmer for 10 minutes, stirring occasionally. Remove from heat.

Oat Crumb Bars

  1. Preheat oven to 350ºF. Line an 8" square pan with foil and grease foil with nonstick spray.
  2. In a bowl, whisk together 8 1/2 ounces (2 cups, spoon and level) pastry flour, 2 7/8 ounces (1 cup) oats, baking soda, and salt.
  3. In a separate bowl, combine brown sugar, coconut oil, egg, and vanilla and whisk until smooth. Fold into dry ingredients just until evenly incorporated.
  4. Set aside 7 1/4 ounces (3/4 cup) batter and press the remaining batter into the bottom of the prepared pan in a flat, compact layer. Pour strawberry filling on top and spread out evenly.
  5. Add the remaining 1 ounce (1/4 cup, spoon and level) flour and 3/4 ounce (1/4 cup) oats to the reserved batter and rub in with fingertips until evenly combined and crumbly. Scatter evenly over strawberry layer.
  6. Bake bars in preheated oven for about 30 minutes, until top is golden and a toothpick inserted into the center comes out free of batter. Cool in pan completely, and then use foil to lift out before slicing. Store in an airtight container in the refrigerator.
