Trail Mix Cookies are soft and chewy oatmeal cookies loaded with the salty-sweet flavors your crave. A healthy cookie recipe, Trail Mix Cookies include whole wheat flour and a reduced amount of butter, but they are so soft and flavorful, no one will know your secret!
1cupfavorite trail mix - or any combo of: toasted nuts, peanuts, almonds, walnuts, pecans—I used peanuts and almonds, baking chips (chocolate, peanut butter, M&M pieces—I used regular M&Ms), dried fruit (raisins, dried cranberries, dried cherries—I used cherries and raisins)
Place a rack in the center and upper third of the oven and preheat to 350 degrees F. Line 2 baking sheets with parchment paper or silpat mats, and set aside.
In a medium bowl, whisk together the oats, all-purpose flour, whole wheat flour, baking powder, baking soda, salt, and cinnamon. Set aside.
In the bowl of a standing mixer fitted with a paddle attachment or a large mixing bowl, cream together the butter and sugars until light and fluffy (about 3 to 5 minutes). Add the egg, egg white, scrape down the bowl, then add vanilla and beat again, just until combined.
Change speed to low and gradually add the flour mixture, until just incorporated. Do not overmix. Add your trail mix (or nut/chip/fruit combination). Beat in the trail mix at low speed until nearly incorporated. Stop mixture and finish incorporating the trail mix by hand with a spatula.
Scoop dough by tablespoonfuls into your hands, then roll into a ball, wetting hands as needed to prevent the dough from sticking (alternatively, you can use a cookie scoop or very small ice cream scoop). Place doughballs 2 inches apart on prepared baking sheets.
Bake for 9 minutes (cookies will appear underdone), then remove from the oven and allow to cool on the cookie sheet for 2 minutes. Transfer to a wire rack to cool completely (or not).
Store cookies at room temperature in an airtight container, separating layers with waxed paper for up to 1 week (they will soften as time goes on). Unbaked dough will keep in the refrigerator for 5 days or can be frozen for up to 3 months.
