In a small bowl, stir together the ground flaxseeds and water. Let sit for 5 minutes to thicken.
2 TBS ground flaxseeds, ¼ cup water
In a medium bowl, whisk together the whole wheat flour, baking soda, baking powder, salt, and cinnamon. Set aside.
1½ cups (190 g) whole wheat flour, 1 tsp baking soda, 1 tsp baking powder, ½ tsp kosher salt, 1 tsp cinnamon
In a large mixing bowl, whisk together the melted coconut oil, honey, and vanilla extract. Add the flax egg and whisk.
¾ cup (170 g) melted coconut oil, ¾ cup (240 g) honey, 2 tsp vanilla
Mix the dry ingredients into the wet mixture until just combined.
Gently fold in the old-fashioned oats and raisins until evenly distributed.
2½ cups old fashioned oats, 1 cup raisins
Cover the bowl and let the dough sit at room temperature for about 15–20 minutes. This helps the oats absorb some moisture and improves texture. While the dough is resting, preheat your oven to 375° F.
Scoop the dough into balls about 2 tablespoons each (50 grams) and place on a baking sheet. Gently press each ball down slightly to flatten.
Bake for 10–12 minutes, or until the edges are lightly golden and the centers are just set.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Enjoy!
