Preheat oven to 350 degrees F. Line a cookie sheet with parchment.
In a small bowl or mug, make the flax egg: mix the water and flax meal together and let it sit for 5 minutes until it forms a gel.
In a large bowl, cream the butter and sugars until light and fluffy. Add the flax egg and vanilla and continue to mix.
Add the gluten free flour, baking soda, and salt. Mix until combined.
Stop the mixer and stir in the oats. Once combined, gently stir in the strawberries. Drop the dough by rounded tablespoons onto the cookie sheet.
Bake at 350 degrees F for 12-15 minutes until golden brown. Allow to cool fully on the cookie sheet.
Notes
Store these in an airtight container for 2-3 days. If you plan to keep them beyond that, I recommend the refrigerator.If you don't love strawberries, try blueberries or raspberries.If you aren't gluten free you can use regular flour.
