In a large bowl mix the oats, flaxseed and mix-ins until combined.

Add in the nut butter and liquid sweetener and stir well until a sticky, uniform dough forms. Feel free to use your hands!

With damp hands, pour the dough onto a silicone baking mat or parchment paper and flatten it into a square about ¾ inch thick. (You can also use an 8x8 pan.)

Place the flattened dough into the refrigerator for about ½ hour. Remove and cut into squares or rectangles.

Store in the fridge.
