Preheat the oven to 350 degrees.
In a large bowl, mix the oat flour and cinnamon.
Add the flax eggs and date paste, and stir to combine.
Add the nondairy milk and stir into a thick batter.
To make the crumb topping, mix the oats, date paste, and cinnamon.
Portion 1/4 c of the muffin batter into a nonstick or lined muffin tin, and top each with about 1 tbsp of the crumb topping.
Bake the muffins for 15 minutes.
Let the muffins cool for at least 30 minutes before carefully removing, then let it sit and cool completely. The muffins are pretty soft and delicate when they’re done baking, but will firm up a lot as they cool.
Store leftovers in the refrigerator.
