In a bowl or a stand mixer add all of the ingredients except chocolate chips. Mix by hand or with a mixer until a dough forms. The texture will be like a dense cookie dough.
Fold in chocolate chips
Press the mixture into an 8x4 pan lined with parchment paper.
Freeze for 1 hour so the bars can set. Cut into 8 even slices and serve. (Sprinkle with sea salt - optional)
Leftovers can be individually wrapped and stored in the fridge up to a week or freezer for 3 months.
