In a medium sized bowl, combine dry ingredients and mix well.
Gently melt butter in a saucepan on the stove.
Combine the melted butter and coconut sugar in a medium sized bowl and whisk together.
Add one egg and two egg yolks one at a time and whisk until well combined.
Stir in vanilla extract.
Roughly chop the semi-sweet chocolate.
Set aside a small amount of chopped chocolate for topping the cookies before baking.
Add the dry ingredients to the wet ingredients and stir until just combined.
Stir in roughly chopped semi-sweet chocolate, except the amount you reserved for topping the cookies.
Cover your bowl and chill the dough in the fridge for 2-3 hours.
When you’re ready to bake, preheat the oven to 375 degrees F.
Roll cookie dough balls into 2-tbsp size portions. You can fit 6 cookies to a sheet as they will spread as they bake.
Top each cookie dough ball with a few pieces of reserved chopped chocolate.
Bake cookies for 8-10 minutes. (They take exactly 10 mins in my oven)
Tap baking sheets lightly when the cookies come out of the oven to deflate them slightly.
Sprinkle with flaky salt.
Let cool and enjoy! (Makes 18-20 cookies)
