Lightly spray the Deep Dish Cookie Pan with Cooking Spray, and set aside. In a mixing bowl, mix the Butter and Sugar, until it's light and creamy. Add Vanilla, Egg and Milk, one tablespoon of jam and mix until well blended. In a separate bowl, add the Flour, and Baking Powder, and stir. Add the package of Dried Blueberries (About 8 ounces) to the Flour mixture. Add the Flour/blueberry mixture to the mixing bowl, and mix until blended.

Using a cookie scoop, or a Tablespoon, place a large dollop of the dough in the deep dish cookie pan, and place a teaspoon of Blueberry Jam in the center. Place another dollop of dough on the top of the Jam, enough to cover, and pinch into the bottom part of the dough. Place in the oven at 350 and bake for 12 to 15 minutes, or until cookies are baked to a golden brown. Remove from the oven to a wire rack to cool. When cool, serve, and enjoy!
