Super Yummy Peanut Butter and Chocolate Oat Squares

Super Yummy Peanut Butter and Chocolate Oat Squares
As shared from the kitchen of  Once Upon a Plate by Mari *
Makes a 10-inch x 15-inch pan (cut the portions any size you like)


3/4 cup EACH of the following:

-Brown Sugar
-Granulated Sugar
-Peanut Butter, smooth or chunky

2 whole eggs
1 teaspoon vanilla extract
3/4 teaspoon baking soda
1/2 teaspoon salt
1-1/2 cups all purpose flour
1-1/2 cups rolled oats (regular or old fashioned)
3/4 cup peanut butter
1 cup granulated sugar
1/2 cup evaporated milk, (I used heavy cream)
5 tablespoons butter
1 cup milk chocolate chips (I used semi-sweet, can you dark chocolate if you prefer)
Position oven rack to center position. Preheat oven to 350* F
Spray cooking oil (or grease) a 10-inch by 15-inch rimmed baking pan, set aside.

In a medium-size bowl whisk together flour, baking soda and salt. Set aside.
Cream together butter, brown sugar, granulated sugar and peanut butter in a large mixing bowl (can use stand mixer, or hand-held electric mixer.) 
Add eggs and vanilla to butter mixture, beat until combined. Add flour in 2 additions, mix well but do not over-beat.  Stir in oats by hand until evenly distributed.
Using a silicone spatula, spread mixture evenly into prepared baking pan.  (May use wet hands to press the mixture in evenly if you prefer.) Bake in a preheated oven for 12 to 15 minutes, until golden brown and slightly firm. (Ovens vary ~ mine took 20 minutes to bake.)
Remove from oven, (and while cookie base is still piping hot), quickly place spoonfuls of the peanut butter (from Topping ingredients), all over the surface. As the peanut butter melts, spread evenly over the surface of the cookie base with a knife or spatula.  Allow to cool completely (set on a cake/baking rack to facilitate faster cooling.)
When cool, make the chocolate topping:  Bring sugar, cream (or evap. milk) and butter to a full, rolling boil. Boil for 45 seconds.  Remove pan from heat, add the chocolate chips. Whisk gently, or stir until chocolate mixture is smooth. As soon as mixture is smooth, pour evenly over the thoroughly cooled cookie and peanut butter base.  Allow chocolate to set up and harden.  When set, cut into squares or bars and enjoy!
