Using a skillet allows for the cookie to get very nicely browned edges and bottom. Also, it makes for a great presentation for family or guests! Why not make it even more fantastic by scooping a big dollop of whipped cream or keto ice cream on top!
Preheat an oven to 375 F. Combine both sweeteners and vanilla extract in a heatproof bowl.
Heat the butter in a 10” cast iron skillet until melted. Continue to heat over medium heat until the butter starting to turn brown and smells nutty about 2-3 minutes. Make sure to stir constantly while the butter is browning.
Pour hot butter onto both sweeteners and vanilla extract in the mixing bowl. Add the eggs and mix until well combined.
Mix the almond flour, baking powder, and salt together.
Then add this to the butter mixture and mix well with a spoon.
Fold in the chocolate chips. Wipe out any excess butter in the cast iron skillet, but leave enough to grease the pan.
Add in the dough and press it smooth.
Bake for 22-25 minutes until the top is nicely golden brown and cooked through. Allow to cool slightly before serving.
