Are peanut butter pies keto?
No, a classic peanut butter pie is not keto-friendly as it contains many high-carb ingredients including confectioners sugar, a graham cracker crust or an Oreo biscuits crust, and sweetened whipped cream.
How can I make keto peanut butter pie?
Luckily, there is an easy way to make a delicious easy keto peanut butter pie at home with only a few ingredients.
Let’s see below the ingredients you need to make the no-bake peanut butter pie crust and then the fluffy peanut butter filling.
No-bake keto crust
This keto peanut butter pie recipe is made with a no-bake chocolate pie crust. While a classic no-bake pie crust contains a lot of store-bought sugar-loaded ingredients like Graham crackers or Oreo, here the crust is made with:
Melted coconut oil or melted butter – I personally prefer melted coconut oil as it firms up better and the no-bake keto crust is much crunchier.
Making the crust
Simply bring all the ingredients above into a large mixing bowl and stir to combine.
You may want to use your hands to squeeze the ingredients together and form a consistent dough. It will be sticky but not wet and should look like a crumble that sticks together really well if squeezed in your hands.
Pressing the dough into a 9-inch pan
I love to use a removable-bottom pan or pyrex pan for this recipe. The removable bottom pie pan is great if you want to transfer the whole sugar-free peanut butter pie onto a pie plate.
But it’s lovely to serve the pie in a pyrex dish and it slices pretty well.
Place the dough in the greased pan of your choice and press all around the pan to evenly cover the bottom and borders.

It is great to use the back of teaspoon to smooth the dough onto the pan.
This is a no-bake sugar-free peanut butter pie crust and it gets all its texture in the fridge.
The cold from the fridge firms up the crust and solidifies the coconut oil or butter to create a delicious no-bake chocolate crust.
No-bake cream cheese peanut butter pie filling
Meanwhile, prepare the keto peanut butter cream cheese pie filling. In a large mixing bowl add the following ingredients:
Soft cream cheese – you can use any cream cheese even lactose-free or vegan cream cheese if you want a dairy-free option. I recommend removing the cream cheese from the fridge 1 hour before making the recipe. It makes it easier to whip with the electric beater.
Heavy cream – or canned coconut cream but keep in mind that this option ups the carbs and add a strong coconut flavor to the pie. Note that unsweetened almond milk is not an option here. It makes the filling very runny and doesn’t create a rich, creamy filling also decreasing the fat.
Natural peanut butter – make sure you are using a healthy peanut butter brand, which means peanut butter that only contains peanut, and eventually salt. But the ingredient list shouldn’t include sugar or added vegetable oils. These ingredients are not keto-approved.
Powdered erythritol – or any keto powdered sweeteners like powdered xylitol or allulose. Don’t use crystal sweetener for the filling. This will leave crunchy sweetener bites in the peanut butter mousse.
To make a fluffy, light peanut butter cream cheese filling, you must use:
a stand mixer with the whisk attachment
or an electric beater
Whisk the ingredients on low-speed at first, this prevents the cream cheese and cream from bursting out of the mixing bowl.
Then, increase to high speed to add air to the mixture and create a fluffy cream cheese filling.
Assembling the low-carb peanut butter cream cheese pie
Remove the no-bake crust from the fridge and pour the peanut butter mixture in the center of the pan. Use a spatula to spread the filling all over the crust.
Return the pan to the fridge for 1 hour to set the filling.
Decorating your low carb peanut butter pie

Grease a 9-inch round pie pan with butter or coconut oil. Set aside.
In a large mixing bowl, combine all the dry ingredients: almond flour, unsweetened cocoa powder, and erythritol.
Stir in melted coconut oil, water and vanilla and combine until soft and stick easily together. It shouldn't be overly wet but sticky. If too wet, add more almond flour. If too dry, add 1 tablespoon more water.
Press the dough with your fingers to evenly cover the bottom and sides of the pan. You can use the back of a spoon to smoothen the surface perfectly.
Place in the fridge while making the filling. This step will also harden the no-bake crust.
Keto peanut butter filling
In a large mixing bowl, using an electric beater, beat soft cream cheese with peanut butter, vanilla extract, powdered sweetener, and heavy cream until thick and slightly fluffy.
Stop the beater and remove the pie crust from the fridge.
Spread the fluffy peanut butter filling into the pie pan.
Chill 1-2 hours or overnight, covered with a piece of plastic wrap to prevent the top from drying out.
