Plum Jam Crumb Cake Recipes

PLUM COBBLER BARS

Steps:

• In a large pot, combine plums and 1 1/2 cups/300 grams granulated sugar. Heat over medium-low heat, stirring occasionally, until fruit releases juices and becomes very tender, 12 to 15 minutes. Meanwhile, place a small plate in the refrigerator to chill. You'll use this later to check the doneness of the jam.
• Purée plum mixture in pot using an immersion blender (be careful of splashing), or remove from pot and purée in a blender or food processor until relatively smooth. Return purée to pot if you removed it, and cook over medium-low heat, stirring occasionally, until mixture thickens and reduces by about half, about 10 minutes. You should end up with about 3 1/2 cups/840 milliliters plum jam. (You can test the doneness by spooning a small amount of the jam onto the chilled plate, returning it to the refrigerator and letting it sit for 2 minutes. It should keep a clean line when you run your finger through it.)
• In a small bowl, whisk remaining 1/3 cup/65 grams granulated sugar with cornstarch to combine. Whisk sugar-cornstarch mixture into jam and cook, stirring occasionally, until it simmers. Simmer for 1 minute, stirring well to prevent scorching. Stir in vanilla extract, and cool plum mixture to room temperature.
• Heat oven to 350 degrees, and line a 9-by-13-inch pan with parchment paper with overhang on all sides. In a large bowl, combine oats, flour, whole wheat flour, brown sugar, baking powder, salt and cinnamon. Add melted butter and stir until the mixture forms streusel-like crumbs.
• Press 2/3 of crumb mixture into an even layer at bottom of prepared pan. Spread cooled plum jam in an even layer over crust, then sprinkle remaining crumb mixture evenly over top of jam.
• Bake until jam bubbles at edges and streusel is lightly browned, 45 to 55 minutes. Cool completely before slicing into 12 pieces.

PLUM CRUMBLE CAKE

Steps:

• Heat oven to 180C/160C fan/gas 4. Grease and line a 22cm deep, round cake tin (preferably with a loose bottom) with baking parchment.
• First make the topping: put all the crumble ingredients in a bowl and rub together until crumbly.
• For the cake, put the butter, sugar, eggs, flour, baking powder, vanilla, ground almonds and soured cream in a big bowl. Beat with an electric whisk until smooth, then tip into the tin and level the top. Arrange the plums, cut-side up, over the mix, then scatter over the crumble.
• Bake for 50 mins-1 hr on a middle shelf until a skewer poked into the cake mixture comes out clean (plums will remain sticky, however). Cool in the tin for 20 mins, then finish cooling on a wire rack. Serve plain or with soured cream or yogurt. Keeps for 3-4 days in an airtight cake tin.

JAM CRUMB CAKE

Steps:

• Make cake:
• Preheat oven to 400°F with rack in middle. Generously butter a 9-inch square or round cake pan.
• Whisk together flour, sugar, baking powder, and salt.
• Whisk together butter, milk, and egg in a large bowl, then whisk in flour mixture until just combined. Pour batter into cake pan. Dollop jam all over surface, then swirl into batter with spoon.
• Make crumb topping:
• Whisk together butter, sugars, cinnamon, and salt until smooth. Stir in flour, then blend with your fingertips until incorporated. Sprinkle crumbs in large clumps over top of cake.
• Bake cake until a wooden pick inserted in center comes out clean and sides begin to pull away from pan, about 25 minutes. Cool in pan on a rack 5 minutes.

PLUM-JAM CRUMB CAKE

Steps:

• Topping: Preheat oven to 350 degrees. Whisk together flour, brown sugar, and salt in a small bowl. Stir in butter until combined.
• Cake: Brush a 9-by-9-by-2-inch square cake pan (not nonstick) with butter. Line with parchment, leaving a 2-inch overhang on two sides; butter parchment.
• Whisk together flour, baking powder, and salt in a medium bowl. In another bowl, beat butter with granulated sugar on medium-high speed until light and fluffy, about 2 minutes. Add eggs, one at a time, beating to combine after each. Reduce speed to low and add flour mixture in 3 batches, alternating with 2 additions of milk, beating until combined and scraping down bowl as necessary.
• Transfer batter to prepared pan. Spread jam evenly over top. Sprinkle evenly with topping, squeezing to create large clumps. Bake until a tester inserted in center comes out clean, 45 to 50 minutes. Let cool in pan on a wire rack 20 minutes. Use parchment to lift cake out of pan, then let cool completely on rack before serving.
