Mix oats into oat flour in a blender and wash the blueberries.
In a mixing bowl, combine spelt flour, oat flour, baking powder, baking soda, coconut sugar and salt.
Then, in a separate mixing bowl, whisk together coconut yogurt, oat milk, olive oil, nut butter, lemon juice.
Add the mixture to the dry ingredients. Mix everything into a creamy dough and now stir the blueberries into the dough.
Grease the muffin cups with a little butter/margarine. Pour the batter into the muffin cups.
Bake the muffins at 350°F for about 20 - 25 minutes. If you're not sure use the toothpick test. Simply stick a toothpick into the muffin. If the toothpick is clean then the muffins are ready.
Let the muffins cool briefly and enjoy them while they are still warm.
