Description

The ultimate skillet cookie, stuffed with your favourite chocolate candy bars.


Ingredients

Scale
  • 1/2 cup unsalted butter, melted & cooled
  • 1/2 cup brown sugar, packed
  • 1 egg 
  • 2 tsp vanilla
  • 3/4 cup all-purpose flour
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 3/4 cup chocolate candy bars of choice, roughly chopped

Instructions

  1. Preheat oven to 350F.
  2. In a medium mixing bowl, whisk together the melted & cooled butter, brown sugar, egg, and vanilla.
  3. Fold in the flour, baking soda, and salt.
  4. Fold in the chopped chocolate candy bars.
  5. Place dough in a greased 8-inch cast iron skillet (or round pie dish, or 8×8 square baking dish) and spread evenly to the edges (if you are doubling the recipe, use a larger cast iron skillet size!). 
  6. Bake for 18-20 minutes (depending on how baked/gooey you want it). The edges should be golden brown and the centre should be soft & just baked.
  7. Let cool in the pan for a few minutes, then top with vanilla ice cream (or whatever you’d like) and enjoy!
  8. Store in a sealed airtight container at room temperature for 5 days.

Notes

For Vegan: Use vegan unsalted butter (can be stick form or spreadable, though results will vary depending on the type/brand you use!). Replace the egg with either 3 tbsp aquafaba or 1 flax egg (1 tbsp ground flaxseed + 2.5 tbsp water).

For Gluten Free: Use gluten free flour. You can use GF all-purpose flour (it doesn’t have to have xanthan gum), buckwheat flour, or oat flour. I don’t recommend using almond flour, since it is not a 1:1 ratio to all-purpose flour!

For Nut Free: Use nut free chocolate candy bars.
