Print Recipe

Ingredients
  

  • 1/2 cup unsalted butter melted (microwave works great)
  • 1 large egg
  • 3/4 cup dark brown sugar
  • 1/4 cup confectioner's sugar
  • 1 tablespoon vanilla extract
  • 1 1/2 cups all purpose flour
  • 1/2 teaspoon baking soda
  • pinch of salt
  • 1 cup Reese's Peanut Butter mini cups
  • 1 cup diced Kit Kat bar
  • 1/2 can of sweet condensed milk

Instructions
 

  • Preheat oven to 350F and line 9x9 inch baking pan with aluminum foil on the inside
  • Melt butter in microwave for 1 minute. Let butter cool a little. Add egg, sugars, vanilla to butter and whisk till well combined (1 min). Add flour, baking soda, salt, and stir till incorporated.
  • Put half the batter into the pan. Sprinkle peanut butter cups and kit kats. Pour sweet condensed milk over the top (see picture). Crumble the second half of the batter into 1 inch wide chunks and sprinkle it on top.
  • Bake until toothpick inserted into the center comes out without batter (30 min). Edges will look golden and firm. The sweet condensed milk will be jiggly.
  • Let cool in the refrigerator until everything is set and firm (3 hours). Lift out using the foil overhangs and cut into squares. Bars will keep 1 week in an airtight container at room temp, and you an freeze them for 3 months!
