Add flaxseed meal and water in a small bowl. Set aside for 5 minutes.
1 TBS flaxseed meal, ¼ cup water
In a medium bowl combine flour, cinnamon, salt, and baking powder. Set aside.
¾ cup whole wheat flour, 1 tsp cinnamon, ½ tsp kosher salt, ¼ tsp baking powder
In a large bowl, beat the butter, sugar, and vanilla with a hand mixer for 2 minutes. Scrape the bowl down. Then beat for 1 minute more.
1 stick softened butter, ¼ cup + 2 TBS brown sugar, ½ tsp vanilla extract
Add flaxseed and water mixture to the butter mixture and beat for 2 minutes. The mixture will look broken and lumpy, keep beating until mostly smooth.
On low, mix in the dry ingredients.
Fold in the oats and raisins. The dough will be sticky.
1 ½ cup old fashioned oats, ¾ cup raisins
Cover the bowl of dough and let sit at room temperature for 15-30 minutes.
Place an oven rack in the center of the oven. Heat the oven to 350℉.
Form the dough into 10 balls that are 50-60 grams each. Place 5 dough balls on a cookie sheet and press into 3 inch diameter discs with clean, damp fingers.
Bake until crisp on the edges and just set in the center, 12-15 minutes.
