Preparation

• Start by heating your flour. You can microwave for 1 minute, stirring every 20 seconds, or bake at 350º F for 5 minutes. You want the flour to be 160º F. Let it cool.
• Line a 9-inch baking dish with foil or parchment paper.
• Combine butter, sugar, and brown sugar together in a large bowl. Mix at medium speed until combined.
• Add peanut butter and the vanilla, mix until well blended.
• Stir in the flour mixing until just incorporated.
• Slowly add oats, 1 cup at a time until it forms a dough.
• Fold in M&M's. Press into prepared pan.
• In a microwave safe bowl melt together chocolate and heavy cream, in 30 second increments. Once smooth, pour over cookie dough mixture. Sprinkle with remaining M&M's.
• Refrigerate for 1-2 hours, or until chocolate is completely set up before serving.
