Baking Instructions
  1. Preheat oven to 350°F (175°C).
  2. In a bowl, whisk together melted butter and brown sugar substitute until smooth.
  3. Add the egg yolk, vanilla extract, salt, and baking soda. Mix well.
  4. Stir in oat flour until a dough forms.
  5. Fold in sugar-free chocolate chips and chopped dark chocolate.
  6. Spread dough evenly into a small cast iron skillet (6–8 inches).

Notes

  • Don’t overbake—the cookie should stay soft in the middle.
  • For a dairy-free version, replace butter with coconut oil or vegan butter.
  • Serve warm for the best texture and flavor.
