These Peanut Butter and Jelly Bars have a soft peanut butter cookie crust, a layer of jam and all the flavors of the classic sandwich. A perfect dessert for bake sales, parties or lunch box treats.
Preheat oven to 375°F and line a 9x13 baking dish with parchment paper leaving an inch overhang on the long sides. Or grease the baking dish with nonstick cooking spray.
In the bowl of a stand mixer fitted with the paddle attachment, or with hand beaters, cream together the softened butter, brown sugar and granulated sugar until light and fluffy, about 2-3 minutes.
Add the egg and vanilla extract and mix together until creamy.
Add the peanut butter and mix together until fluffy and creamy.
Add the dry ingredients: baking soda, salt and all purpose flour. Mix on low speed just until fully incorporated.
Take ¾ of the cookie dough and pat it into an even layer in the prepared baking dish.
Then evenly spread the jam over the dough.
Place chunks of the remaining dough over the top of the jam.
Bake bars in preheated oven on center rack for 20-25 minutes or until the edges and top are golden brown.
