How to Make Keto Cupcakes

- Preheat oven to 175C/350F.
- Line a standard 12 cup muffin tin with silicone cupcake molds or cupcake papers.
- In a bowl add the peanut butter, melted butter, erythritol, salt, vanilla, and baking powder.
- Cream ingredients together using a hand mixer.
- Add the eggs, one by one, mixing in between.
- Add the cocoa powder and the coconut flour and mix until combined, followed by the almond milk. Mix well. Allow the mixture to sit for 2 minutes, so the coconut flour can soak up all the liquid.
- Evenly spoon the mixture amongst the 12 prepared muffin tin holes.
- Bake for 15-20 minutes. Cupcakes are cooked when an inserted skewer comes out with a few crumbs clinging to it, or spring back when touched.
- Set aside to cool.
- How to make Sugar-Free Peanut Butter Cupcake Frosting:
- In a mixing bowl, add the softened butter and peanut butter. Cream with the whisk attachment on your hand mixer until smooth.
- Add the powdered erythritol a few tablespoons at a time on low speed, until it is all mixed it.
- If your frosting is too firm, add the heavy cream a tablespoon at a time until your frosting is smooth and pipeable.
- Spoon your frosting into a piping bag with a star nozzle tip and pipe the frosting onto your cooled cupcakes.
- Enjoy immediately or refrigerate for 30 minutes to firm up the frosting.
