5-Ingredient No-Bake Oatmeal Peanut Butter Cookies

No-Bake Oatmeal Peanut Butter Cookies made with 5 simple ingredients! This easy no-bake peanut butter cookies recipe is made with all wholesome ingredients for a healthier treat. Perfect for enjoying all summer long when it’s too hot to bake!

As a follow-up to my 6-Ingredient No-Bake Cookies recipe, I’m back with a chocolate-free version that uses peanut butter.

My original recipe for no-bake cookies calls for cocoa powder, almond butter and honey and this time we’re changing it up for the peanut butter lovers out there who don’t love chocolate.

At a baseline, all you need is four simple ingredients to make this recipe work: peanut butter, pure maple syrup (or honey), coconut oil (or butter), and oats. 

The combination of these ingredients results in a luxurious cookie that is just so addictive! It’s nearly impossible to stop at one.

Plus, the recipe is so easy to make and a fun little project for kids who are aspiring bakers.

You can use this delicious treat as a blank canvas for all your no bake cookies recipe adventures.

Let’s discuss the healthy ingredients for this addictive no bake cookie recipe.

Ingredients for No-Bake Oatmeal Peanut Butter Cookies:

Unsweetened Creamy Peanut Butter: The reason we’re all here and the glue that holds it all together! Choose your favorite peanut butter, be it creamy, chunky, or natural.

I use unsweetened natural peanut butter because I like keeping the cookies refined sugar-free using pure maple syrup.

I know what you’re wondering, and yes, you can use almond butter or sunflower seed butter! In fact, I shared my Almond Butter No-Bake Cookies recipe recently.

You can use any nut butter or seed butter here as long as it is thick, sticky, and well-stirred. Whatever you use, just be sure there isn’t a lot of oil separation and that the nut butter isn’t too thick (some cashew butters may be tough to work with).

Pure Maple Syrup (or Honey): We use a liquid sweetener like pure maple syrup or honey to keep the cookies refined sugar-free but also to provide a sticky substance to help the cookie ingredients stay held together nicely. 

Coconut Oil or Unsalted Butter: The fat portion of the recipe which makes the cookies taste incredibly rich or creamy! Use melted coconut oil or melted butter.

For vegan no-bake cookies, stick with coconut oil. I prefer the flavor of the butter because I find the cookies taste luxurious, but I also enjoy the coconut oil version too.

Pure Vanilla Extract: While the pure vanilla extract is optional, it adds a nice warm flavor to the cookies.

Rolled Oats or Quick Oats: Pick your favorite type of oats for these delicious no-bake oatmeal cookies. Old-fashioned oats, quick-cooking oats, and instant oats all work.

For gluten free no-bake cookies, be sure to use gluten free oats.  I use sprouted gluten-free oats. Old fashioned oats will result in a chewy texture where quick oats will be a bit smoother.

Sea Salt: Whatever you do, don’t skip the sea salt! A pinch of salt enhances all of the flavors so that the cookies are an explosion of peanut butter flavor and taste very sweet without the need for added sugar. 

Optional Additions:

• If you enjoy chocolate, mix up to 1 cup of chocolate chips into the cookie mixture. Be sure the mixture is at room temperature when you do so or the chocolate chips will melt (which wouldn’t be the end of the world in my opinion). Semi-sweet chocolate chips, white chocolate chips, peanut butter chips, mini chocolate chips, sugar-free chocolate chips and dark chocolate chips are all great options.
• Add in ½ to ⅔ cup chopped walnuts or pecans if you love nutty cookies.
• Are you a fan of dried fruit? Add up to ⅔ cup raisins, dried cranberries, dried blueberries or any dried fruits you love.
• For sweeter cookies, add 1 to 3 tablespoons of brown sugar.
• For me, the best results come from using peanut butter, pure maple syrup, quick oats, butter and chocolate chips. This really is the perfect treat for satisfying that sweet tooth!

Now that we’ve covered the simple pantry ingredients list for no bake peanut butter oatmeal cookies in detail, let’s make some cookies!

How to Make No-Bake Oatmeal Peanut Butter Cookies:

Line a large baking sheet with parchment paper or wax paper.

Add the peanut butter, pure maple syrup and butter (or coconut oil) to a saucepan and heat it over medium heat, stirring constantly. Continue heating and stirring just until everything is well-combined and creamy. There’s no need to bring the mixture to a full boil.

Remove the peanut butter mixture from the heat and stir in the vanilla extract (if adding), oats, and sea salt until everything is well-combined. The end result will be a very thick and sticky dough – this is normal.

Drop mounds of cookie dough in a single layer onto the prepared baking sheet using a spoon.

The cookies will stay the exact size and shape as you place them on the cookie sheet, so you can shape them accordingly. You can make any size cookies you like! I tend to make enormous cookies.

Refrigerate for 2 hours or freeze for 15 minutes, or until the cookies have set up. The amount of time it takes to chill the cookies depends on the temperature of the ingredients going into the refrigerator or freezer.

The cookies are ready when they are no longer sticky to the touch and peel off of the parchment paper easily.

Store cookies in an airtight container or a zip lock bag in the refrigerator for up to 10 days. You can freeze cookies in a freezer bag for up to 3 months.

This easy no-bake dessert recipe can be made any time of year but is particularly useful during the summer months when you’re craving a sweet treat but don’t want to turn on the oven.
