Best 4 Blackberry Jam Bars Recipes

BLACKBERRY CRUMB BARS

Steps:

• Preheat oven to 350 degrees. Butter an 8-inch square baking pan. Line bottom with parchment paper, leaving an overhang on two sides; butter and flour paper, tapping out excess.
• Make topping: In a medium bowl, whisk together melted butter, brown sugar, and 1/4 teaspoon salt; add 1 cup flour, and mix with a fork until large moist crumbs form. Refrigerate topping until ready to use.
• In a medium bowl, whisk together remaining 3/4 cup flour, baking powder, and remaining 1/4 teaspoon salt; set aside. In a large bowl, using an electric mixer, beat room-temperature butter, confectioners' sugar, and vanilla until light and fluffy; add eggs, one at a time, beating well after each addition. Reduce speed to low; mix in flour mixture. Spread batter evenly in pan; sprinkle with blackberries, then chilled topping.
• Bake until golden and a toothpick inserted in center comes out with moist crumbs attached, 40 to 45 minutes. Cool completely in pan. Using paper overhang, lift cake onto a work surface; cut into 16 squares.

JAM BARS

Steps:

• Place dry ingredients in a bowl.
• Stir in oats and sugar.
• Cut in margarine until crumbly.
• Pat 2/3 of crumbs in a 11 by 17 inch pan.
• Spread with jam and top with remaining crumbs.
• Bake at 375° for about 45 minutes (or until light brown around edges).
• Cool and cut into bars.

BLACKBERRY SHORTBREAD BARS

Steps:

• Beat butter in a bowl with an electric mixer until light and fluffy. Add egg yolks to butter one at a time, blending well after each addition.
• Mix flour, white sugar, baking powder, cardamom, and salt together in a bowl. Stir flour mixture into butter mixture until just combined. Divide dough in half and wrap each tightly in plastic wrap. Freeze for at least 3 hours.
• Preheat oven to 350 degrees F (175 degrees C).
• Grate 1 ball of frozen dough evenly into the bottom of a 9x13-inch baking pan. Spread blackberry jam over grated dough, leaving 1/2-inch space around the edges. Grate the second ball of frozen dough over the jam.
• Bake in the preheated oven until golden brown, 30 to 40 minutes. After shortbread cools, sprinkle with confectioners' sugar and cut into bars.

BLUEBERRY JAM BARS

Steps:

• For the quick blueberry jam: Stir together the blueberries, sugar, lemon zest and juice in a medium saucepan over medium heat and cook until the berries release some liquid and soften, 1 to 2 minutes. Mash the mixture with a potato masher until the berries break down, decrease to medium-low heat and cook until the sugar dissolves, 3 to 5 minutes. Sprinkle the cornstarch over top, stir and cook until the jam thickens enough to coat the back of a spoon nicely, about 1 minute. Remove from the heat and allow to cool completely, 30 minutes.
• For the crumble: Preheat the oven to 350 degrees F. Grease a 9-inch square baking dish with cooking spray and line with parchment paper.
• Cream the butter, granulated sugar and brown sugar in a stand mixer fitted with the paddle attachment until light and fluffy, 2 to 3 minutes. Add the vanilla and mix gently until combined.
• Add the flour, 1 cup oats, salt, baking powder and cinnamon and mix on low speed until just combined, scraping down the sides of the bowl as needed. Transfer 1/2 cup of the mixture to a medium bowl and set aside. Press the remaining mixture evenly into the bottom of the prepared baking dish.
• Stir the remaining 1/2 cup oats and chopped pecans into the reserved mixture in the medium bowl. Refrigerate the mixture until the jam is cooled completely.
• Spread the cooled jam evenly over the crust and sprinkle the crumble on top. Bake until golden brown and set, 30 to 35 minutes. Transfer the baking dish to a wire rack and allow to cool completely, about 1 hour. Slice and serve.
