Perfectly equal parts chewy, crusty, and soft, these Peanut Butter Oatmeal CookieBars are one of the best chocolate-peanut butter cookie desserts around. This simple dessert recipe, made with chocolate chips, is prepared in only 30 minutes!
In a large mixing bowl, cream together shortening, butter, and sugars.
Add peanut butter, and combine.
Add eggs, one at a time, mixing to combine.
Add all of the dry ingredients, and mix until incorporated.
In a small saucepan or a double boiler, combine chocolate chips, milk, and butter. Heat on medium-low, until just melted.
Put 2/3 of the cookie mixture in the bottom of a greased large sheet pan or cookie sheet (you know, jelly-roll sized). Press down evenly with your hands.
Spread the chocolate mixture over the crust. Break up and sprinkle the remaining cooking mixture evenly over the top of the chocolate.
Bake in a preheated oven (350 degrees F.) for 12 to 15 minutes, until the cookie top turns a light golden brown. Let cool completely before cutting.
Notes
I bet that you could half this recipe and put it in a 9-by-13-inch pan, but then what would you do with the other half a can of sweet milk? Just make the whole thing and love it!
For a less sweet cookie bar, use dark chocolate chips.
Store the bars in an airtight container for up to one week.
These bars freeze well. Cut into squares and store in a freezer bag or airtight container for up to two months.
