Preheat your oven to 350°F and line a baking sheet with parchment.
Combine the flax seed and water in a small bowl and set aside.
Melt the butter in the microwave in a large bowl. Add the brown sugar, maple syrup, and vanilla extract and stir to combine. Add the flax seed mixture and stir again. Add the cocoa powder, salt, and baking powder and stir until fully incorporated – this can take a while.
Finally, add the flour and chocolate chips at the same time and stir until just combined.
Scoop tablespoons of the dough onto the parchment-lined baking sheet. Press a caramel into the top of each cookie. Use a spoon to scoop a little more dough on top of the caramel, then use your fingers to seal the dough around the caramel (greasing your fingers with a bit of spray oil helps with this).
Sprinkle a bit of sea salt on top of each cookie.
Bake for 9-10 minutes, then transfer to a wire rack to cool. Enjoy!
– I have a recipe for vegan caramels here, or you can buy some on Amazon here.
– If you’re not vegan, you can totally use regular caramels.
