  • 56 g salted butter
  • 60 g coconut sugar or light brown sugar

  • 1 egg yolk
  • 1 teaspoon vanilla extract
  • 64 g all-purpose flour
  • ½ teaspoon baking soda
  • 18 g rolled oats
  • 12 g almond flour
  • 3 tablespoon M&Ms + more for the tops or chocolate chips


  • Line a baking sheet with parchment paper. Set aside.
  • In a medium microwave-safe bowl, add in the butter.
  • Microwave the butter for 20-25 seconds, until the butter is partially melted.
  • Add in the coconut sugar and granulated sugar and whisk until combined with the butter.
  • Next, add the egg yolk and vanilla extract into the bowl and whisk until lightened and incorporated.
  • Add in the all-purpose flour, baking soda, rolled oats and almond flour.
  • Use a spatula to gently combine the dry ingredients with the wet ingredients.
  • Add in the M&Ms and fold it into the cookie dough using the spatula.
  • Use a 1 tablespoon cookie scoop to scoop the dough onto a lined baking sheet.
  • Place the cookie dough into the fridge or freezer to chill for 30 minutes.
  • Preheat oven to 350°F/177°C.
  • Arrange the cookie dough onto a lined baking sheet with at least 2" in between.
  • Bake the cookies at 350°F/177°C for 9-11 minutes, until slightly puffed up.
  • Remove the baking tray and carefully bang it on a counter once or twice to flatten (if you prefer a less puffy cookie).
  • Let cool on the cookie sheet for 5 minutes before carefully transferring to a wire rack to completely cool.
