Plum Vanilla Crumble Bars

First, make the crumble topping, then the shortbread. While the shortbread is baking, make the plum filling. Assemble and bake together.

Crumble topping:

1/2 cup dark or light brown sugar

1/2 cup flour

1/4 cup oatmeal

1/2 teaspoon sea salt

4 tablespoons (1/2 stick) cold butter

Mix dry ingredients in a medium bowl.  Cut butter into cubes then, using a pastry cutter, cut into dry mixture until pea-sized mixture is formed (should be crumbly-looking).  Place in fridge until ready to use.

Shortbread crust:

1 3/4 cups flour

1/4 teaspoon salt

1 1/2 sticks of butter (3/4 cup)

1/4 cup sugar

1/4 cup confectioners sugar

1 teaspoon vanilla

Heat oven to 325° F.

Combine flour and salt in a small bowl; set aside.

Cream butter and both sugars together. Add vanilla and mix, then slowly incorporate flour mixture until combined.

Press into a greased 8 x 8 baking dish (lining the pan with parchment paper can make it easier to remove bars).  Press shortbread dough into the pan, spreading evenly.

Bake for 15 minutes.

Plum filling: 

5-6 cups plums, pitted and sliced (or cherries, blueberries, etc)

1 cup water

1 1/2 cups sugar

1 teaspoon vanilla paste or vanilla extract

Add plums and water to wide pan and heat through, then add sugar and vanilla paste,  Cook over medium heat until fruit begins to break down, about 30 minutes.

Let mixture cool a bit, then transfer to food processor and give it a whirl.  Put the mixture back in the pan and continue to cook until a thick paste forms, making sure to stir constantly; it will burn if you don't stir!

When you can scrape your spoon through the mixture and you see a trail, you’re almost done. This should take about 15 minutes. (Make sure you really cook this down enough. If you don’t, the filling will be too runny and not hold the bar shape. You have to get all the water out of the fruit.) Once you see a thick paste form, remove from heat; spread over shortbread and sprinkle crumble topping onto the fruit filling layer.

Bake at 325° F for 20 to 30 minutes, or until the topping begins to brown.  Remove from oven and let cool. Cut into bars to serve. Store in fridge to keep filling firm.
