🔪 How to Make Keto Peanut Butter Cookies

Preheat your oven to 350°F.

Add all ingredients to a mixing bowl, except for the almond flour.

Mix using a hand mixer until well combined.

Add in the almond flour, then mix using a silicone spatula.

Using a cookie scooper, scoop the batter and form into balls.

Place them on a baking sheet lined with parchment paper.

Using a fork, press the balls flat in two different directions, making a crisscross pattern.

Bake for 10–12 minutes or until slightly golden.

Allow to cool completely before serving; this is important! If you do not allow them to cool, they could crumble apart.

💡 Tips for Making Peanut Butter Cookies

• This probably goes without saying, but always make sure you are using the freshest peanut butter. It truly is the main flavor in these cookies so the peanut butter needs to be really fresh.

• While everyone has their favorite peanut butter brands, I was introduced to Crazy Richard’s some time ago, and I haven’t used another brand since. Their peanut butter is rich and creamy, has no preservatives, is non GMO and only has one ingredient: peanuts. Check it out along with their other products on their website.

• These gluten free peanut butter cookies tend to be much more delicate than traditional cookies. The key to keeping them together is to let them set up when you take them out of the oven by not removing them from the sheet pan until they are completely cooled.

☑️ Storage Instructions

Allow them to cool completely before placing them in an airtight container. They can be kept at room temperature for up to a week or stored in the refrigerator for up to two weeks.

For longer storage, you can freeze them for up to three months. Just thaw them room temperature when you're ready to enjoy them again.

🔄 Substitutions and Additions

Here are some popular options, but keep in mind that most substitutions can affect the overall texture and, in some cases, the flavor of these cookies.

• Peanut butter: Swap the smooth peanut butter for chunky peanut butter, or use almond butter instead.

• Butter: You can use coconut oil or ghee for a dairy-free alternative.

• Almond flour: Substitute with coconut flour, adjusting the quantity as needed.

• Nuts: Add ¼ cup of chopped nuts (such as pecans, walnuts, or almonds) for added texture.

• Chocolate chips: Mix in ¼ cup of sugar-free chocolate chips for a chocolatey twist.

• Spices: Add ¼ teaspoon of cinnamon or pumpkin spice for a warm, cozy flavor.

• Sea salt: Sprinkle a pinch of sea salt on top of each cookie before baking for a sweet and salty combination.

• Coconut: Stir in ¼ cup of unsweetened shredded coconut for extra flavor and texture.

What Sweetener is Best for Keto Peanut Butter Cookies?

Though there are several wonderful sugar substitutes on the market, I've tested them and found that a monk fruit/allulose blend with brown serve combination gives you the best texture and flavor.

Are Peanut Butter Cookies Keto?

These Keto cookies do not contain any flour, making them much lower in carbs than most other cookie recipes.

Peanut butter is the main ingredient although where peanuts are a legume, they are high in fat and fiber, making them perfectly okay for Keto when eaten in moderation.

The real question if peanut butter is Keto, boils down to what ingredients are used to make it. Unfortunately, some of the brands we grew up with in our PB&J sandwiches contain a significant amount of sugar.

When you’re selecting a Keto friendly peanut butter, you want to look for one that says, ” All Natural,” and also indicates there is no sugar added.

Why Are My Keto Cookies Falling Apart?

If your cookies are too soft, they may need more time to cool and firm up after baking. Ensure you allow them to cool completely on the baking sheet before transferring them to a cooling rack. This cooling process helps them set and hold their shape.

Why Are The Bottoms Turning Too Brown?

You should not have that issue with this recipe, but some ovens do bake differently. Dark bottoms on your cookies are a result of baking at too high a temperature or placing the baking sheet too close to the heating element. Try reducing the oven temperature by 25°F and moving the rack to a higher position in the oven for more even baking.
