Super yummy blondie bars that are super addicting. They're perfect, thick and fudgy chocolate chip blondies baked with toasty marshmallow chunks and Reese's Peanut Butter Cups. Watch 'em disappear!
Annalise's Tip: These bars freeze great. Let them cool completely, cut,and freeze in a freezer bag or airtight container for up to 3 months. Let thaw on the counter for a few hours or overnight before serving!
