Preheat oven to 350 degrees. Butter or spray a mini muffin pan with non-stick cooking spray thoroughly. These babies like to stick a little, so grease the cups well.
Break up the streusel crumb topping mixture with a fork until pebbly and set aside.
Press small mounds of cookie dough, about 1 tablespoon-size, into each cup as though making a thick cookie crust (as opposed to a thin pie crust that will just crumble when you try to remove it from the mini muffin pan). The crust should come up to just below the rim of the cup and there should be a small indention in each cup for the filling.
Place about 1 teaspoon of jam/pie filling in each indentation, then top the filled cookies with a generous sprinkle of streusel mixture.
Bake for 18 to 20 minutes, until the top edges of the cookies are golden brown and the crumb mixture is golden.
Allow cookies to cool in pan for 10 minutes, then carefully remove and allow to cool directly on wire rack until completely cool.
Store, uncovered or lightly covered, at room temperature
