Plum Meyer Lemon Jam Coffee Cake




1/4 cup all-purpose flour
1/4 cup finely ground almonds
1/4 cup sugar
1 tsp. ground cinnamon
4 Tablespoons butter
8 oz mascarpone, at room temperature
1/2 cup butter, softened
1 1/4 cups sugar
2 large eggs
2 cups all purpose flour
1 1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup buttermilk
1/2 cup sour cream
10 oz. plum lemon jam (or other)

Combine first 4 ingredients; cut in butter with a pastry blender until mixture is crumbly. Sprinkle in a greased and floured 12-cup Bundt pan; set aside.
Beat mascarpone cheese, butter and sugar at medium speed with an electric mixer until creamy. Add eggs, one at a time, beating well after each addition. Combine flour and baking soda, add to the mascarpone cheese mixture alternately with the buttermilk and sour cream, beginning and ending with the flour mixture. Spoon half of batter into prepared pan, spoon jam over batter, being careful not to allow the jam to touch the sides of the pan, top with the remaining batter.
Bake at 350 degrees F. for about an hour or until cake tests done. Cool in pan on a wire rack for ten minutes; remove from pan, and cool on wire rack.
