    • Eggs
    • Oat Fiber

    How to Make Chocolate Keto Cupcakes with Peanut Butter Frosting

    To Make the Gluten Free Cupcakes

    Preheat oven to 350F.

    Add the egg whites to a bowl, whip them to stiff peaks and set aside.

    In a separate bowl, add the almond flour, cocoa powder, salt, oat fiber, and baking powder. Whisk together and set aside.

    In another bowl, using a hand mixer, combine the egg yolks and Swerve confectioners.

    Add in the heavy cream, sour cream, vanilla and coffee extracts and mix until combined.

    Mix in the dry ingredients until combined.

    Fold in the egg whites, careful not to deflate them.

    Scoop the batter into silicone cupcake liners  or a greased muffin pan.  Bake for 15-18 minutes or until a toothpick, when inserted, comes out clean.  Allow to cool completely before frosting.

    To Make the Low Carb Peanut Butter Frosting

    Whip the mascarpone and butter together in a bowl using a hand mixer.

    Add most of the heavy cream (reserving about a tablespoon), Swerve confectioners, peanut butter and vanilla extract, then mix until smooth and creamy.

    Pour in more of the heavy cream if needed, to get your desired consistency.

    Add the frosting to a piping bag fitted with the tip of your choice (ziplock bag with the tip cut off will work too), and chill in the fridge until the cupcakes have cooled completely.   Frost the low carb chocolate cupcakes and finish with a dusting of unsweetened cocoa powder.

    Is Peanut Butter Keto?

    Peanuts are naturally high in fat and fiber, making them perfectly fine for Keto when eaten in moderation. But, the real question as to 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.

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

    How Many Carbs in a Chocolate Cupcake?

    Traditional cupcakes have approximately 65 grams of carbs. Needless to say they are out of the question for low carb diets.

    However, these chocolate cupcakes made with almond flour takes all that worry away by reducing the carbs to 3 nets carbs per serving, including the frosting! So go ahead and indulge in these delicious guilt free treats!

    What is Oat Fiber? Is Oat Fiber Keto?

    Oat Fiber is made from grinding the outer husks of oats. How healthy is oat fiber? It's pure insoluble fiber, which doesn't dissolve in water and isn't broken down in the digestive tract, so it has zero net carbs and is perfect for a Keto Diet. It helps give a more traditional texture and that's why I use it so often. Check out all the Keto Oat Fiber Recipes you can make!

    What is a Substitute for Oat Fiber?

    To get the best results, it's best to use oat fiber if you can. If you're unable to find it, try a combination of psyllium husk powder and coconut flour. Since both are very absorbent, you might have to add more liquid.

      Can I use psyllium husk powder in place of the oat fiber?

        I've never tried subbing with psyllium husk powder before, so I can't say for sure how it might turn out. The oat fiber really helps the texture in these cupcakes, so if you are able to use it, I highly recommend it.
