Preparation
- Step 1
Prepare strawberry purée: In a blender, combine strawberries and jam. Make a paste of cornstarch and vanilla, and add to blender. Purée until smooth.Set aside.
- Step 2
Prepare cake: Heat oven to 375 degrees. Oil a 9-inch springform pan and set aside. In a large bowl, combine sugar, flour, baking powder and baking soda. Sprinkle in butter cubes and rub them in by hand until mixture resembles large coarse crumbs. Remove ½ cup and set it aside. To large bowl, add sour cream,egg and vanilla. Mix well.
- Step 3
Using a little over half the cake batter, drop dollops of batter into pan. Pat batter across bottom of pan and about 1 inch up sides; mixture will be very sticky and somewhat uneven. Add strawberry purée, making an even layer across bottom of pan and leaving a rim of dough above it. Cover with remaining cake mixture.
- Step 4
Prepare crumble topping: In a medium bowl, combine reserved ½ cup dough and Demerara sugar. Stir with a fork to mix. Sprinkle evenly over cake.
- Step 5
Bake cake until lightly golden, about 45 minutes. Cool completely before serving.

This was delicious but I wasn't sure it would turn out that way. The batter is very thick and sticky, almost like dough, though not hard to pat across the bottom of the pan. However the puree was very liquidy. Thick, sticky batter doesn't spread over a soft liquid surface. The batter and the puree just got mixed together as I tried to distribute the batter on top of the puree. I thought it would be a disaster but in the end it worked out great and everyone loved it.
Made a half recipe of this. It fits well in a 6" dia springform pan. I used canned apricot halves and apricot jam for the puree. Also diced up some dried apricots, then macerated overnight with a little Cointreau, to go on top of the puree. Swapped out 1 tsp vanilla with almond extract and added sliced almonds to the crumble topping. Got raves from the friend I made it for -- she says it needs to be in the permanent rotation.
I used a pastry blender to cut the butter into the dry ingredients and it worked just fine. Have these tools gone out of fashion?
So yummy! Made this as outlined but added 1/4 tsp of salt to the dry mixture, as recommended by other, and flour as sub. for cornstarch. I didn't have a 9" pan so I used a 12-cupcake pan instead, worked perfectly and actually kind of easier I'd imagine than having to spread that thick paste over a pan, I just dolloped in each one for all the batter.
My apology in advance. I’m guilty of hacking these recipes: for instance, cake needs oil, not butter, in the same quantities. I used sour cream once, but got loftier results with Greek yogurt. I’ve used frozen raspberries mixed with raspberry preserves, pears cut into small chunks mixed with dried cranberries heated and cooled in apricot jam and cardamom. Today I’m using pineapple and coconut with the apricot jam and grated ginger. The cake is a workhorse and open to adding a spice. Used a springform pan because I can’t guess the rise. Other than that, followed the recipe!
Made you a potluck and everyone loved it. I made some changes suggested by others. The strawberries and jam when into my blender. Then I used my cuisinart for the dry ingredients. I sliced the cold butter into half inch pieces and just let the food processor do its wonderful thing? The dough was super easy to dollop into the spring bottom pan. Next time I might cook the strawberry corn starch mixture for a bit to make it thicker. It was tasty but really a show stopping part of the cake.
