It turns out that mini tarts taste exactly like giant thumbprint cookies; both of which are delicious.
Blackberry Jam Tart with Brown Sugar Crust
Makes 1 9-inch or 4 mini 6-inch tarts
Inspired by this tart from David Lebovitz
1 1/2 cups flour
3/4 teaspoon baking powder
hearty pinch of salt
1/2 cup brown sugar
1/4 cup butter, room temperature
1 tablespoon heavy cream
1 tablespoon bourbon
1 cup blackberry jam
coarse sugar for sprinkling, optional
In a small bowl, combine the flour, baking powder and salt. In a medium bowl, beat together the butter and the brown sugar until light and fluffy.
Add egg, cream, and bourbon, to the butter mixture, and stir until combined. Add the flour in two batches, stirring completely after each addition.
Wrap dough in plastic, and chill in the refrigerator for 4 hours or overnight.
When you are ready to bake the tarts, preheat the oven to 375.
Divide the dough into five equal portions. Roll one portion of the dough into a log about 1 inch diameter, wrap in plastic and chill in the fridge. On a floured surface, roll out the dough to about 1/4 inch thick and carefully transfer it to the tart pans. Trim the dough so there is about an inch of overhang, then fold over and crimp to create double-thick sides. Spoon about 1/4 cup of jam into each shell. Slice the log into rounds about 1/4 inch thick, and cover the tart with as many rounds as can fit comfortably. Sprinkle with coarse sugar.
Bake for about 20-25 minutes, or until the crust is brown, and the jam is bubbly.
