Ingredients
- 1 cup Smucker’s® Red Raspberry Preserves
- Nonstick Cooking Spray, as needed
- 1 1/2 cup Butter
- 3/4 cup Granulated Sugar
- 3/4 cup Brown Sugar
- 3 cup All-Purpose Flour
- 1 1/2 cup Old Fashioned Rolled Oats
- 1/2 teaspoon Salt
Instructions
- Step 1: Heat oven to 350 degrees F (180 degrees C). Coat a large baking pan with nonstick cooking spray or butter, or line it with parchment paper.
- Step 2: In a large bowl, beat butter, granulated sugar, and brown sugar with a mixer on medium-high speed until the mixture is light and fluffy.
- Step 3: Add all-purpose flour, rolled oats, and salt to the bowl. Mix on low speed until all ingredients are blended.
- Step 4: Measure out 2 ½ cups of the dough and set it aside. Press the remaining dough evenly into the prepared baking pan to form the crust. Bake this crust for 15 minutes.
- Step 5: Remove the pan from the oven. Stir the raspberry preserves, then spoon it evenly over the baked crust. Finely crumble the reserved dough over the fruit filling.
- Step 6: Bake the assembled bars for 30 to 35 minutes until the topping is lightly browned. Cool completely in the pan on a wire rack before cutting and serving.
Tips & Variations
- Use your favorite fruit preserves, such as strawberry or apricot, for a different flavor twist.
- For a nuttier bar, add 1/2 cup chopped nuts like walnuts or pecans to the oat mixture.
- If you prefer a softer bar, reduce baking time by a few minutes and check frequently.
Storage
Store jam bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week. To reheat, warm briefly in the microwave or enjoy at room temperature.
