Preparation

Step 1

1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.

2. In a large, microwave-safe bowl melt the butter, abt 1 min

3. Wait momentarily before adding the egg so you don't scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.

4. Add the PB and whisk or stir until smooth and incorporated.

5. Add the flour and stir until just combined, don't overmix.

6. Add all remaining add-ins and fold to incorporate.

7. Put the batter into prepared pan, smoothing the top lightly with a spatula. (Sprinkle a few M&Ms on the top.)

8. Bake for about 25 min, or until top is set. A toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter. Allow bars to cool in pan for at least 30 min before slicing and serving.

**Bars will keep airtight at room temp for up to 1 week, or in the freezer for up to 6 months.
