Step 1

Preheat oven to 350°F and grease a 9x13-inch baking dish with nonstick spray. Set aside.

Step 2

In a large bowl, stir together the flour, oats, sugar, salt, and baking soda. Add butter and mix in with your hands until crumbly.

Step 3

Set aside 1 1/2 cups of the oat mixture and press the remaining mixture into the bottom of the prepared pan.

Step 4

In a medium bowl, stir together the peanut butter, sweetened condensed milk, and vanilla until combined.

Step 5

Pour peanut butter mixture over the oat layer and spread out evenly. Sprinkle chocolate chips over the top.

Step 6

Top with remaining oat mixture and press down lightly. Bake until edges are lightly golden, about 30 minutes.

Step 7

Let cool completely before slicing and serving. Enjoy!
