Berry Easy Jam Bars

Recipe by Sarah Jampel
Bake it Easy: Summer

These super easy jam bars fulfill three major requirements: You don’t need a mixer (yes!), you don’t prebake the crust (yes!), and you don’t pre-cook the fruit (yes!). Instead, just stir together a buttery, brown sugary, oat-bolstered dough; toss fresh berries — try a combination of blueberries, raspberries, and blackberries — with lemon juice, more sugar, and flour; and sandwich the two together. The hardest part is waiting for the jam bars to cool before you dig in.

Instructions

Prevent your screen from going dark as you follow along.
  1. Preheat the oven to 375°F with a rack in the center. Line an 8" pan with parchment on all sides, then lightly grease. 

  2. In a large bowl, whisk together all of the dough ingredients except the butter. Use your fingers or a spoon to break up any brown sugar lumps. Add the melted butter and stir until fully combined and smooth.

  3. Transfer about 2/3 of the dough (roughly 2 2/3 cups or 485g) to the prepared pan and press into an even layer. 

  4. In another large bowl, gently mix together all of the filling ingredients until the berries are evenly coated. Transfer the fruit to the pan and distribute it into an even layer. 

  5. Crumble the remaining dough (about 1 1/3 cups or 240g) over the berries; squeeze the dough together to make bigger clumps or tease it apart for finer crumbles. (Even coverage is not important at this step.)

  6. In a small bowl, combine the topping ingredients. Then sprinkle the cinnamon sugar evenly over the top of the bars.

  7. Bake the jam bars for 50 to 55 minutes, covering the pan with foil if the top is browning too quickly, until the berries are bubbling and the topping is baked through. 

  8. Let the bars cool completely in the pan (or for at least 1 1/2 hours; if you’re really in a rush, you can stick them briefly in the refrigerator or freezer to expedite the process). As they cool, use a small offset spatula or knife to dislodge any jam from the sides to make removing them from the pan easier.

  9. Remove the bars from the pan using the parchment as a sling, then slice and serve.

  10. Store the sliced jam bars in an airtight container in the refrigerator for up to 4 days. They’re delightful cold.

Tips from our Bakers

  • To make these gluten-free, replace the flour in the dough with an equal amount of Gluten-Free Measure for Measure Flour. In place of the flour in the filling, use 1 tablespoon (7g) cornstarch.
