Ingredients

  • 1/2 cup margarine
  • 2 cups sugar
  • 2 3/4 cups quick oats
  • 1/2 cup milk
  • 2/3 cup peanut butter

Instructions

  1. Mix together margarine, milk, and sugar in a heavy 2-quart pan. Bring to a boil and boil for 2 1/2 minutes.
  2. Remove from heat, add peanut butter and mix thoroughly.
  3. Stir in oats.
  4. Drop by teaspoon onto waxed paper.

Tips & Substitutions

For a richer flavor, consider using unsalted butter instead of margarine. If you're out of quick oats, you can blend rolled oats in a food processor for a finer texture. To make these cookies a bit healthier, you can reduce the sugar by half a cup or substitute with honey or maple syrup. If you prefer a nuttier taste, try adding chopped nuts or chocolate chips.

Serving Suggestions

These unbaked peanut butter cookies are perfect for an afternoon snack or as a sweet treat for gatherings. They pair beautifully with a glass of cold milk or a cup of hot coffee. For a fun twist, serve them alongside some Oatmeal Cookies (No-Bake) for variety. They also make a great addition to lunchboxes or as a quick energy boost before outdoor activities.

Storage & Reheating

Store the unbaked cookies in an airtight container at room temperature for up to a week. If you have leftovers, you can refrigerate them to extend their freshness. There's no need to reheat these cookies, as they are meant to be enjoyed as is; however, if you prefer them warm, a quick 5-10 seconds in the microwave will do the trick.

Frequently Asked Questions

Can I use natural peanut butter instead of regular peanut butter?

Yes, you can use natural peanut butter, but keep in mind that it may alter the texture slightly. Natural peanut butter tends to be less processed and can be runnier, so you might want to refrigerate the cookies after making them to help them set properly.

How long do the cookies need to set before they're ready to eat?

The cookies usually need about 30 minutes to set on the waxed paper. However, you can enjoy them as soon as they are dropped, as they are meant to be eaten unbaked. Just be aware that they will be softer if not allowed to set.

Can I add chocolate chips to the cookie mixture?

Absolutely! Adding chocolate chips is a delicious twist. Simply fold in about a cup of chocolate chips after mixing in the oats. This will give your cookies a delightful chocolatey flavor that complements the peanut butter perfectly.
