My youngest daughter made this peanut butter oatmeal cookies when we were craving something a bit sweet one night. Use either a subtle hint or load up the peanuts and I bet y’all will love them too. (affiliate links present)

Quaker Oats Peanut Butter Oatmeal Cookies

Years ago we made these peanut butter cookie brownies and they were just over the top I tell you. They weren’t really homemade as we used cake mix as the base, so we thought we’d integrate Old Fashioned oats this go around.

If you don’t cook or bake with kids currently I would encourage you to do so with this great recipe. It is a life lesson they’ll need forever more and measurements can be sort of a math lesson (but they won’t realize it).

Traces of the mixture cover the bowl and whisk attachment, hinting at the start of a delicious peanut butter oatmeal cookie recipe.

Peanut Butter Oatmeal Chocolate Chip Cookies Ingredients

  1. Mixer or 2 large bowls
  2. Old Fashioned oats
  3. Creamy peanut butter
    1. I wouldn’t use natural peanut butter
    2. You could use crunchy peanut butter
  4. Butter
  5. Brown sugar
  6. Eggs
  7. Vanilla
  8. All purpose flour
  9. Baking soda and salt
  10. Milk Chocolate chips are optional, 1/2 cup or peanut butter chips are wonderful

And a non stick baking sheet so you can allow them to cool just like we do with our peanut butter cookies chewy recipe.

A stand mixer bowl filled with a mixture of oatmeal cookie dough and peanut butter is shown from above. The text at the top reads, "Peanut Butter Oatmeal Cookie Recipe.

You could easily fold in 1/2 cup of mini chocolate chips at the end too. That is on our list for next time. I think the key to any cookie with add ins is to mix all the ingredients together and then fold in what might break apart. Oats go in last for us on this one. Chocolate chips and/or raisins would go in last too.

What is a substitute for eggs in peanut butter cookies?

  • If you need an egg free cookie recipe you can also use applesauce instead. Substitute 1/4 cup applesauce for one egg in the cookie recipe.
  • Sunflower butter or almond butter works too
  • This tweak will give the cookie dough moistness and impart the cookies with great flavor.

The only other difference is they may not puff up as you would normally expect, they’re a bit denser if you ask me. I love a chewy cookie though so it is beyond perfect with every bite. Of course if you prefer a crispy outcome just add a few minutes. For me that ruins my treats but to each their own I suppose. 😉

I have a printable recipe cared at the bottom of this post but I will give you a quick rundown here. I would highly recommend using a small cookie scoop so they’re the same size so they bake evenly.

How to Make Homemade Peanut Butter Cookies

  1. Mix together wet ingredients in a bowl
    1. If you want an intense peanut butter flavor add 3 tbsp, for “regular” add 2
  2. In a separate bowl blend together dry ingredients and then slowly integrate the two
  3. Gently fold in oats and any other add ins you’d like
  4. If you chill the dough in the fridge for an hour or so they will maintain a more uniform shape when baked golden brown
  5. Spoon dough onto the prepared baking sheets with space in between
  6. Bake at 350 degrees for 9 minutes.
  7. Remove when the very middle still looks just a bit wet but edges are lightly browned.
  8. Take off cookie sheet and transfer to cooling rack so they can cool completely and maintain chewy texture

in air fryer

No matter whether you bake them or make as Air Fryer Oatmeal Cookies, using more brown sugar than white tends to result in a moister, softer cookie. Benefit to using a small countertop appliance is you can “bake” just a few at a time.

I haven’t doubled the recipe yet but I imagine it would be fine to do so.

What is the secret to soft chewy cookies?

  • If you want to increase chewiness, add an extra egg yolk.
  • Rolling the cookie dough balls to be taller than wider increases thickness.
  • Using melted butter, and little bit more flour increases chewiness as well
  • Taking out when they’re very lightly browned is key, never bake too long
Should I refrigerate cookies after baking?

In general I would say no NO, no! Unless they contain a cream or custard filling they will dry out and harden much faster if stored in the refrigerator. Instead, put into a sealed container or freezer bag free from air on the counter and enjoy again within 3 days.

When should you refrigerate leftover cookies?

if they have a high moisture content or contain perishable ingredients like cream cheese or custard, then refrigeration may be advisable to prevent spoilage. Examples include cheesecake cookies or some filled cookies. If you’re in a very hot and humid environment, refrigerating cookies briefly (1-2 hours) can help set the icing or frosting on decorated cookies.

How long can you freeze cookies?

If you want to store cookies for an extended period, freezing is a better option than refrigeration. Freeze in an airtight container or freezer bags, separating layers with parchment paper, to prevent freezer burn. Frozen, they can then last for several months and can be thawed at room temperature before serving.

Whether you’re making cookies made from cake mix, or homemade from scratch, storing remains the same. Most will stay fresh when stored in an airtight container at room temperature for about three days. If you’re not going to consume them before that, it’s best to freeze them. Here’s a guide to follow;

How do I keep fresh baked cookies fresh longer?

  1. Cool Completely – Allow your freshly baked cookies to cool completely on a wire rack before attempting to store them. This helps prevent excess moisture from getting trapped in the container, which can lead to soggy cookies.
  2. Choose the Right Container
    • Use an airtight container with a tight-sealing lid to store your cookies. Glass or plastic containers with a rubber gasket work well.
  3. Layer
    • Place a sheet of parchment paper or wax paper between layers of cookies to prevent them from sticking together and to maintain their appearance.
  4. Add Moisture Absorbers
    • To prevent from becoming soft or stale due to moisture, you can add moisture absorbers or a slice of bread to the container.
  5. Store at Room Temperature
    • Most baked goods are best stored at room temperature. Keep the container in a cool, dry place away from direct sunlight and heat sources to stay moist.
  6. Use an Airtight Lid
    • Ensure that the container’s lid is airtight and properly sealed each time you close it. This prevents air and moisture from entering.
  7. Avoid Excess Air – If using resealable plastic bags, press out excess air before sealing them.
  8. Freeze for Longer Term Storage
    • If you want to keep cookies fresh for an extended period, freeze them. Wrap cookies in airtight packaging and store them in the freezer. Frozen cookies can stay good for several months.

How to Fix Stale Cookies

  1. If your cookies lose their freshness, you can try reviving them by placing them in a preheated oven at a low temperature, around 300 degrees F for a few minutes. Check them regularly to prevent over-baking.
  2. Sprinkling a fleck of water to add moisture to begin with helps too
  3. Keep a close eye on them as it doesn’t take long

  1. We loved it! I didn’t have white flour and used almond flour but they were delicious! My junk food loving boys begged me to make them again!

  2. This combination of flavors is terrific!! Go ahead and add chocolate chips to the batter — even better!! My husband is allergic to walnuts and pecans, so I use crunchy peanut butter and don’t even miss the nuts. Our new favorite cookie!!
