Crust & Crumbs

  • 3/4 cup unsalted butter, melted
  • 1/2 cup sugar
  • 1/4 cup light brown sugar
  • 1 tsp vanilla extract
  • 1/2 tsp pure almond extract
  • 2 cups flour
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 3 Tbsp sliced almonds


  • 3/4 cup berry jam (or favorite jam)


  • 1 Tbsp unsalted butter, melted
  • pinch of salt
  • 1 tsp vanilla extract
  • 3/4 cup powdered sugar
  • 2 Tbsp milk


  1. Preheat oven to 350°F and line an 8-inch square baking pan with parchment paper. Whisk together melted butter, sugar, brown sugar, vanilla, and almond extract in a large bowl until combined.
  2. Whisk together flour, baking soda, and salt in a medium bowl; add to butter mixture and fold in until incorporated. Set aside 3/4 cup of dough for topping, mixing in sliced almonds until mixture is crumbly. Chill until ready to use.
  3. Press remaining dough evenly into bottom of prepared baking pan. Bake crust for 14 to 16 minutes, until lightly golden and set. Transfer to a wire rack and cool for 15 minutes.
  4. Place jam in a small bowl and microwave for 10 seconds; whisk to loosen. Spread jam evenly over cooled crust and crumble reserved dough over jam layer.
  5. Bake for another 30 to 35 minutes, or until topping is golden and filling slightly bubbly. Cool completely in pan on a wire rack.
  6. For the glaze, whisk together melted butter, salt, vanilla, powdered sugar, and milk in a small bowl. Drizzle glaze over cooled bars and let set. Carefully lift parchment and place bars on a cutting board; cut into squares with a sharp knife.

Larger Batch: For a larger batch of crumb bars, double the recipe and bake in a 9 x 13-inch rectangular baking pan.

Freeze Crumb Bars: To freeze crumb bars, let cool completely. Once cooled, place the unglazed bars on a baking sheet and freeze flat for 1 hour. Transfer bars to an airtight container and freeze up to 8 weeks. Thaw bars overnight in the refrigerator and glaze before serving.
