In a small bowl combine ground flaxseed (or egg replacer) and water. Let sit for 2-5 minutes before adding to recipe.
In a medium bowl combine gluten free flour, cinnamon, baking soda, and salt and whisk to combine.
In a large bowl beat sugars, softened butter, and flax egg until fluffy.
Add dry ingredients to wet a little at a time and mix until combined.
Fold in vegan chocolate chips, oats, and raisins one at a time. Cover dough and place in the fridge for 30 minutes.
Preheat oven to 350 degrees Fahrenheit.
Form dough into 1" balls and place about 2" apart on the baking sheet. Bake for 10-12 minutes, until edges are golden brown. The middle of the cookies will still be soft.
Remove from oven and let cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. Repeat for remaining dough.
Store leftover cookies (if there are any) in an airtight container for up to 4 days.
*different gluten free flour blends may require more or less flour than 1 1/2 cups. I recommend adding small spoonfuls at a time as needed until the dough is not sticky and holds together in a ball.
