Step by step instructions

You can see me making this keto cookie recipe in this short video or read the step-by-step instructions below.

It only takes about 5 minutes to mix the batter and then you’ll have a delicious snack ready to eat all week long!

Step 1: Preheat oven to 350°F (180°C) and line a baking sheet with parchment paper. Put aside.

Step 2: Add erythritol to Nutribullet or blender and mix until powder. Put aside. If you are using a low carb confectionery sweetener, you can skip this step.

Step 3: Add a cup of peanut butter, egg, powdered erythritol, baking soda, and vanilla extract to a medium bowl. Mix until a smooth, shiny dough forms.

Step 4: Roll out about 2 tablespoons of cookie dough between your hands to form a ball, then place it on the prepared baking sheet. Repeat the process until all the dough is used up. You should get 12-14 cookies.

Step 5: Use a fork to flatten the cookies, creating a criss-cross pattern on top.

Step 6: Bake cookies for 12-15 minutes.

Step 7: Remove from oven and allow to cool on baking sheet for 25 minutes, then transfer to cooling rack for another 15 minutes.

Expert advice

Even if your cookies smell amazing when they come out of the oven, resist the temptation to try one right away! Make sure you give them full time to cool on the baking sheet and cooling rack.

Since this recipe does not contain flour, the cooling step is crucial for the cookies to harden. The longer they are able to cool, the better the consistency will be. You don’t want them to fall apart while eating!

Be patient with these. I promise it’s worth it 🙂

Variations

There are several different variations of this recipe that you can try. Don’t be afraid of creativity!

• We all know that peanut butter and chocolate is a classic combination. For a little extra sweetness, add some sugar-free chocolate chips to your chocolate peanut butter cookies.
• For a truly decadent treat, dip each cookie halfway in melted sugar-free dark chocolate to make the ultimate chocolate peanut butter cookies. This takes it to a COMPLETELY new level! Just make sure you let the cookies cool completely before dipping.
• To give your cookies a nutty texture, try using crunchy peanut butter instead of creamy peanut butter.
• You can also replace the peanut butter entirely and use a different peanut butter. Cashew or almond butter would work well in this recipe!

Remember that natural peanut butter will add the most flavor to your cookies, but if you prefer not to use it or are allergic, any peanut butter will do.

Storage

I recommend storing these keto peanut butter cookies in an airtight container in the fridge for up to a week. They will stay fresh, soft and delicious!

For longer storage, you can freeze them instead and enjoy them for several months.

Frequently asked questions

Is peanut butter keto?

Plain peanut butter is keto compliant and suitable for people following a low carb diet. But stick to a good quality peanut butter that is free of added sugars and other additives. Flavored peanut butter is not ideal as it tends to contain more carbs from added sugars and flavorings.

What is the best peanut butter on a keto diet?

Peanut butters that only have 1 or 2 ingredients are best for the keto diet. It should be plain and natural peanut butter containing only peanuts and possibly salt. Chunky or creamy peanut butter is suitable for both keto and low carb diets.

What is the best keto cookie sweetener?

When making keto and low carb cookies, use erythritol-based sweeteners for best results. Erythritol is a sugar alcohol that mimics sugar in its molecular structure. This makes it a great option as it browns nicely giving a very crunchy texture. More importantly, erythritol does not affect blood sugar at all due to its zero carb count. It is an excellent sugar substitute for people with diabetes.
