Below I will answer some common questions I have had in regards to this recipe. I’ll break down the ingredients and substitutions, nutritional information and everything you need to know about eating peanut butter on a keto diet, and the best baking tips too.
Is Peanut Butter Keto Friendly:
Whether you’re following a keto diet for health reasons or for weight loss, this is a common question I have been asked since sharing this recipe. In general, peanuts are seen as a fairly higher carb nut and most peanut butter’s contain a lot of extra sugar.
So how did I make a keto peanut butter cookie? The trick is in the serving size and using a high quality peanut butter with no added sugars.
For example, this recipe uses 1/2 cup of peanut butter. I like the No sugar added Jiff brand which is 16 net carbs in 1/2 cup. Eating that in one serving is definitely not going to benefit anyone following a strict keto diet.
Spread that 16 grams of net carbs into 8-12 servings and the carb count is now much lower without skimping on the delicious peanut butter flavor you want in your cookie!
- Almond Flour – I use a fine almond flour in place of traditional flour in this cookie. You can substitute for coconut flour if desired but use 1/2 cup less (coconut flour absorbs moisture differently) and it may come out a little more crumbly.
- No Sugar Added Peanut Butter- Like I mentioned above, choose a no-sugar added brand of peanut butter. If you prefer almond butter or other nut butters, you can sub as desired.
- Eggs – Eggs work best at room temperature. I like to whisk them into the peanut butter mixture as well. They will act as a binding agent for the almond flour.
- Butter- Softened and salted butter works best. Do not melt the butter!
- Low Carb Sweetener – Choose a sweetener you prefer. I used granulated allulose because I like the effect when baking and it doesn’t have an after taste to me.
- Baking Powder- Leavening agent.
- Xanthan Gum- This works really well to promote a chewier texture to the cookie. When you remove gluten, you lose that effect and this helps! You can sub with cornstarch or arrowroot powder too.
- Keto Chocolate Chips or Dark Chocolate- I use Lilly’s brand or Choc Zero. A solid dark chocolate would work too. Use what fits your diet and macros!
How to make a keto skillet cookie:
This recipe follows a very similar process to most cookie doughs (keto or not). Start by always combining your dry ingredients (almond flour, sweetener, baking powder, xanthan gum) and whisk together until combined.
Take your softened butter and no sugar added peanut butter and whisk that together in a separate bowl. Then beat in the eggs, one at a time.
Fold the peanut butter mixture into your dry ingredients. It will start to look like wet sand, then become a thicker cookie dough base.
Finally add in your chocolate chips and reserve a small amount to push directly into the top to make the cookie skillet look pretty and presentable.
Bake the cookie off in the oven until set, about 25 minutes or so. Let it cool a bit before digging in (because it does taste amazing warm out of the oven).
Other helpful recipe notes:
- This recipe will not work as individual cookies. You can swap out the skillet for an 8×8 inch pan and make them into bars, but a rolled cookie will not form the same way.
- Make sure you’re using a seasoned cast iron skillet. You can also spray the skillet too to help prevent sticking.
- Pair this cookie with my delicious No Churn Keto Ice Cream or even some homemade keto caramel sauce.
- This is a lower carb cookie, but the it is still high in fat. The full nutritional information (fat content, protein, sugars, and net carbs) is listed below.
- 1/2 cup No Sugar Added Peanut Butter
- 4 Tbsp. Butter, softened
- 1 cup Low Carb Sweetener
- 1 1/2 cups Almond Flour
- 2 Eggs
- 1 tsp. Baking Powder
- 1 tsp. Xanthan Gum
- 1/2 cup Sugar Free Chocolate Chips or Super Dark Chocolate
- Preheat your oven to 350 F. Use a 8 inch skillet and grease it if needed.
- In a mixing bowl, mix your dry ingredients together (almond flour, sweetener, baking powder, and xanthan gum).
- In another smaller bowl, combine the peanut butter and softened butter. Then whisk an egg in one at a time until incorporated.
- Fold or mix in the peanut butter mixture into the dry ingredients.
- Mix in your chocolate chips, reserve a few to push directly into the top.
- Pour the cookie dough into your skillet and spread it out until it's evenly spread across the pan. Add the few remaining chips to the top to decorate and press them in slightly.
- Bake an 8 inch skillet for 18-20 minutes. If using mini cast irons pans Bake for about for 8-10 minutes.
- Remove from the oven once the cookie is lightly browned, may still be a bit soft but the dough is set.
- Serve with a scoop of low carb ice cream or serve as is.
Swap put peanut butter for almond butter instead if you prefer!
