Preheat the oven to 350 degrees.
In a large bowl, mix the oat flour, date paste, flax egg, vanilla, and milk until thoroughly combined.
Use a 1/4 cup to portion the batter into the 6 sections of a nonstick or sprayed doughnut pan.
Bake the doughnuts for 15 minutes.
To prepare the glaze, melt the chocolate chips in the microwave - I microwave for about 15 seconds, stir, then 15 seconds again, repeating until they're totally melted.
Once all the chips are melted, add the stevia and stir.
Dip each doughnut into the glaze, and refrigerate for 15 minutes so the glaze can set.
Store leftovers in the refrigerator.
