Ingredients
  

  • 1 cup old-fashioned rolled oats (gluten-free if needed)
  • ¾ cup white whole wheat flour (or substitute all-purpose or gluten-free 1:1 baking flour)
  • cup light brown sugar
  • ¼ teaspoon ground ginger
  • ¼ teaspoon kosher salt
  • 6 tablespoons unsalted butter, melted (or coconut oil for a vegan version)
  • 2 cups small-diced strawberries (about 10 ounces, divided)
  • 1 teaspoon cornstarch
  • 1 tablespoon freshly squeezed lemon juice
  • 1 tablespoon granulated sugar (divided)
  • ½ cup powdered sugar (sifted)
  • ½ teaspoon pure vanilla extract
  • 1 tablespoon milk (any kind)

Instructions
 

  • Preheat your oven to 375°F and position the rack in the center. Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
  • In a medium bowl, mix the oats, flour, brown sugar, ginger, and salt. Stir in melted butter until evenly coated and crumbly.
  • Set aside 1/2 cup of the mixture for the topping. Firmly press the remainder into the base of the baking pan to form a crust.
  • Scatter half of the diced strawberries over the crust. Sprinkle with cornstarch, lemon juice, and ½ tablespoon sugar.
  • Add the remaining strawberries and sprinkle with the remaining sugar. Top evenly with the reserved crumble mixture.
  • Bake for 35-40 minutes. The topping should be golden and the strawberry mixture bubbling.
  • Cool on a wire rack completely—refrigerate to speed up cooling if needed.
  • Mix powdered sugar, vanilla, and milk until smooth for the glaze. Drizzle over cooled bars, slice, and serve.
