Preheat and prep: Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
Whisk the dry ingredients: In a large bowl, mix 1 1/2 cups rolled oats, 1 cup whole wheat flour, 1 teaspoon cinnamon, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.
If using, add a pinch of nutmeg, 1 tablespoon chia or ground flax, and 1 teaspoon orange zest.
Blend the wet ingredients: In another bowl, whisk 1/3 cup melted coconut oil (or softened butter), 1/3 cup nut butter, 1/4 cup maple syrup or honey, 1/4 cup brown sugar, 2 eggs, and 1 teaspoon vanilla until smooth.
Combine gently: Pour the wet mixture into the dry. Stir until just combined. The dough will be thick and slightly sticky.
Fold-ins: Add 3/4 cup raisins and 1/2 cup chopped nuts (if using).
Stir until evenly distributed.
Shape the cookies: Scoop heaping tablespoons (about 2 tablespoons each) onto the baking sheets, spacing a couple inches apart. Gently flatten the tops with your fingers or the back of a spoon to about 1/2-inch thick.
Bake: Bake for 10–12 minutes, until the edges are set and lightly golden but the centers still look soft. Don’t overbake; they’ll firm up as they cool.
Cool: Let them cool on the pan for 5 minutes, then move to a wire rack to finish cooling.
Taste and adjust: Try one.
If you want more sweetness next time, add an extra tablespoon of maple or a handful of raisins. Prefer more chew? Add another couple tablespoons of oats.
