Author: Olivia Johnson


  • 1/2 cup organic, extra-virgin coconut oil
  • 1/2 cup peanut butter (I recommend Wild Friends Peanut Cashew Super Butter; for keto use unsweetened)
  • 3 ounces dark chocolate, broken up into 1-inch pieces (I recommend Sprouts Organic 85% cacao bars; for keto, use chocolate with zero added sugar)
  • 1 teaspoon vanilla extract
  • 1 teaspoon instant coffee (I recommend Sprouts Organic Decaf)
  • 6 drops organic stevia


  • Over high heat, bring a saucepan with 1-2 cups of water to a boil. Add a glass bowl on top of the saucepan to create a double boiler. Melt the coconut oil and peanut butter in the glass bowl, whisking occasionally to combine. 
  • Add the dark chocolate pieces and continue whisking until completely melted and combined. 
  • Remove from heat and add vanilla, coffee and stevia, whisking to combine.
  • Carefully pour chocolate mixture into molds of choice--I recommend these heart silicone molds for a festive Valentine's Day treat. 
  • Allow to cool for 30 minutes, then transfer to the fridge and let firm up for at least 3-4 hours (overnight preferred). Serve and enjoy!


Keeps in the fridge for up to 2 weeks.
Note: you can microwave the coconut oil, peanut butter and dark chocolate to melt if preferred, but it's not as delicate, albeit super convenient.
