  • 1/2 cup granulated sugar
  • 1 teaspoon vanilla extract
  • Pinch of salt

For the Filling:

  • 1 jar (12–16 oz) jam, preserves, or fruit spread (apricot, raspberry, or lemon work well!)
  • Optional Mix-Ins: Chocolate chips, chopped nuts, shredded coconut, or sprinkles

For the Glaze (Optional):

  • 1 cup powdered sugar
  • 2–3 tablespoons milk (or cream)
  • 1/2 teaspoon vanilla extract

Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease a large baking pan (13×18 inches) or line it with parchment paper for easy cleanup.

Step 2: Make the Crust

  • In a large mixing bowl, combine flour, softened butter, sugar, vanilla extract, and salt.
  • Mix with a hand mixer or your hands until the mixture resembles coarse crumbs.
  • Reserve about 1 1/2 cups of the mixture for the topping.
  • Press the remaining mixture evenly into the bottom of the prepared pan to form the crust.

Step 3: Add the Filling

  • Spread jam, preserves, or fruit spread evenly over the crust.
  • If using mix-ins, sprinkle them over the jam layer.

Step 4: Add the Topping

  • Sprinkle the reserved crumb mixture evenly over the jam layer, pressing lightly to help it adhere.

Step 5: Bake the Bars

  • Bake for 25–30 minutes, or until the edges are golden brown and the topping is set.

Step 6: Cool and Glaze (Optional)

  • Let the bars cool completely in the pan on a wire rack.
  • If using glaze, whisk together powdered sugar, milk, and vanilla extract until smooth, then drizzle over the cooled bars.

Step 7: Cut and Serve

  • Cut into squares or rectangles and serve. Smaller pieces work great for parties!
