Finely grated apple keeps these oatmeal cookies soft, while cinnamon and raisins supply familiar lunchbox flavor. The recipe contains no nuts, but every packaged ingredient still needs a school-appropriate allergen check.
Back-to-School Cookies with Apple and Oats
- Prep: 18 minutes
- Bake: 10 to 12 minutes
- Temperature: 350°F
- Yield: 12 cookies
- Pan: Large rimmed sheet pan
Ingredients
- 1 cup old-fashioned rolled oats
- 3/4 cup all-purpose flour
- 1 teaspoon ground cinnamon
- 1/2 teaspoon baking soda
- 1/4 teaspoon kosher salt
- 1/3 cup unsalted butter, softened
- 1/3 cup packed brown sugar
- 1 large egg
- 1 teaspoon vanilla extract

How to Make Lunchbox Cookies
- Heat: Set the oven to 350°F. Line a large rimmed sheet pan with parchment.
- Mix dry: Whisk oats, flour, cinnamon, baking soda, and salt for 30 seconds.
- Cream: Beat butter and brown sugar for 90 seconds. Beat in the egg and vanilla until smooth.
- Drain: Press the grated apple gently in clean towels. It should remain moist but not drip.
- Combine: Stir dry ingredients into wet until no flour remains. Fold in apple and raisins.
- Portion: Scoop 12 equal mounds, spacing them 2 inches apart. Flatten each mound to 1/2 inch thick.
- Bake: Bake 10 to 12 minutes until the edges set and centers no longer look wet.
- Cool: Rest on the pan 8 minutes, then transfer to a rack for at least 30 minutes.

Allergen and Packing Safety
The recipe contains wheat, milk, and egg. “Nut-free” describes the formula, not every manufacturing facility. Follow the FDA allergen guidance, inspect labels, and follow your school’s policy.
Pack only completely cooled cookies in a clean container. Keep perishable lunchbox foods cold using insulated storage and frozen packs; follow USDA refrigeration guidance.
- Store airtight for 2 days.
- Refrigerate up to 5 days.
- Freeze up to 2 months.
- Discard cookies showing mold or an unusual odor.
Soft Cookie Success Tips
Use an apple that feels firm and has no bruised flesh. Grating produces smaller pieces than chopping, so the cookies hold together cleanly.
After adding flour, mix with a spoon rather than an electric mixer. Gentle mixing limits gluten development and preserves a soft, tender center.
The cookies do not spread dramatically. Flattening before baking gives them an even thickness and prevents a doughy mound in the middle.
For make-ahead lunches, freeze cooled cookies individually, then place one frozen cookie in the lunch container. It will thaw gradually before snack time.
Can I omit raisins? Yes. The dough bakes correctly without them; do not replace them with unverified candy when allergen restrictions matter.
