Ingredients

  • 1 1/4 cups gluten-free flour blend (175g)
  • 1/2 tsp baking soda (3g)
  • 1/2 teaspoon salt (3g)
  • 6 tbsp unsalted butter (at room temperature (85g))
  • 1/2 cup brown sugar (100g)
  • 1/4 cup granulated sugar (50g)
  • 1 egg (50g, room temperature)
  • 1/2 tablespoon vanilla extract
  • 1/2 cup mini chocolate chips (80g)
  • 18 mini peanut butter cups
  • 1/3 cup M&Ms (65g)

Instructions

  • Preheat the oven to 350°F (175°C). Line a mini muffin pan with 18 mini paper cups. Set aside.
  • In a medium mixing bowl, combine gluten-free flour blend, baking soda and salt. Whisk to combine. Set aside.
  • In a large mixing bowl, add room temperature butter, brown sugar, and granulated sugar.
  • Cream with an electric mixer for 2-3 minutes, until light and fluffy, scraping down the sides of the bowl with a spatula as needed.
  • Add the egg and vanilla extract and mix until smooth.
  • Add half of the flour mixture to the butter mixture and stir until just combined. Repeat with the remaining flour, stirring until no more streaks of flour remain.
  • Stir in the mini chocolate chips.
  • Spoon the dough into each muffin well.
  • Bake at 350F for 10-12 minutes, until the cookies are puffed up and lightly browned. Do not overbake.
  • Remove from the oven and immediately press the mini peanut butter cups down into the cookies.
  • Once the chocolate on the mini peanut butter cups has melted from the heat of the cookies, add 3 M&Ms to the top of each cookie. Let the cookies cool completely before removing from the muffin wells.

Notes

  • If you have celiac disease or a gluten allergy, it's crucial to double-check all ingredient labels and, if necessary, contact the manufacturer to confirm that the products are completely gluten-free. 
  • I tested this recipe with Bob’s Red Mill 1-to-1 Gluten-Free Baking Flour in the blue bag, which already contains xanthan gum. You do not need to add xanthan gum to this recipe. I cannot verify if other brands of gluten-free flour blends will work, as I have not tested them in this recipe. 
  • For best results, weigh your ingredients using a food scale. The way you measure floor can vastly change the recipe, so weighing it is the easiest way to ensure your recipe turns out perfectly every time. 
  • Keep an eye on the baking time; the cookies should be taken out when they are just set and lightly browned. They will continue to cook slightly once removed from the oven.
