In a medium bowl add all brownie ingredients except milk and chocolate chips. Add enough milk 1 tsp at a time to get a non-sticky brownie batter.
Stir in chocolate chips and make balls of brownie between your palms and place on parchment or muffin cavities, freeze to set, min of 30 minutes.
Add all caramel ingredients in a small bowl and microwave to melt the coconut oil, stir until a smooth caramel is formed. If this is too runny, refrigerate to firm it back up.
Add about 1/2 tbsp caramel on each brownie. (Optional) sprinkle with coarse sea salt. Freeze to set the caramel.
Enjoy from frozen or refrigerated!
Notes
I've made these with oat and coconut flour and both were amazing. They're also great with peanut butter or sun butter.
