M&M's® Pecan Pie Chocolate Cookie Bars

Chocolate Pecan Pie Cookie Bars

These pecan pie cookie bars are made in two steps, the first step is making the cookie bar crust. Then we’ll make the pecan pie topping. This is perfect for when you don’t have time to make a whole pecan pie, but want to experience the pecan flavor of fall, and even right into the holidays (stock up on M&M’s® Pecan Pie before they’re gone!).

Pecan Dessert Bar Recipe

Let’s gather our ingredients and get going on this chocolate pecan pie cookie bars. First, we’ll need our chocolate sandwich cookies, butter, sugar, pecan halves and of course M&M’s® Pecan Pie candies. Get the complete instructions below the tutorial and photos.

Pecan Pie Bars Ingredients

Pecan Pie Chocolate Cookie Crust

For the crust, crush sandwich cookies finely with a rolling pin or crushing them with your hands in a large plastic bag. To speed up the process, use a food processor if you wish. I like using good old fashioned human power though – it’s funner! Combine sandwich cookies and melted butter together using a large spoon — stir well.

OREO Cookie Crust

Prepare a 9×9 baking pan with cooking spray. Press the cookie mixture into the pan. Pack it into the pan very tightly.

Tip: Lightly coat your hand in cooking spray, then pack the crust down tightly. The cooking spray will prevent your hand from sticking to the crust mixture.

Once you have the cookie mixture in the pan, you can move on to the pecan pie topping.

Pecan Cookie Bar Filling Preparation

Pour the mixture over the cookie bar crust, spreading the mixture and pecan halves around evenly.
