Spooky Spellbook Peanut Butter Squares!

It’s sp🎃🎃ky season, and I figured these would be the perfect keto spooky bars to kick off the month of all things spooky. They are so easy to make, sweet, salty, heavy on the peanut butter, extra chocolatey, and totally decked out for Halloween. The perfect spooky treat to enjoy all October long. 👻 - (You won't ''boolieve'', totally delish at only 4g Net Carbs).


For the Filling
  • 3/4 heaping cup Natural Peanut Butter
  • 3 tablespoons Butter
  • 1/2 teaspoon Vanilla Extract
  • 1/4 cup to 1/3 cup Powdered Erythritol, or to desired sweetness
  • 1/4 tsp Salt
  • 2 bags Schoolyard Snacks Peanut Butter Cereal

For the Coating

  • 6 oz Low Carb Milk Chocolate
  • 2 oz Unsweetened Bakers Chocolate + 1/2 teaspoon solid coconut oil
  • 9 Candy Eyeballs (these are not sugar free, but you can also use a little white chocolate for the eyes!)


  1. Add the peanut butter cereal to a food processor and pulse just until crushed and set aside. Line a 6x6 pan with clear plastic wrap. 
  2. In a large bowl melt the butter in the microwave for :30 seconds. Add the natural peanut butter, vanilla, salt, and powdered erythritol and mix until smooth. Fold in the crushed cereal and press into the prepared pan. Refrigerate for 2 hours to set. 
  3. Once set, remove the peanut butter slab from the pan and slice into squares. You should get 9 total. 
  4. Melt the milk chocolate and dark chocolate + coconut oil in two separate bowls. Dip each square in the milk chocolate and remove with a fork, tapping to remove any excess chocolate. Place on parchment and repeat with the remaining squares. Press a candy eye on each square.
  5. Add the melted dark chocolate mixture to a piping bag and cut the tip to form a small opening. If it's too thin, let it cool a bit more, then pipe the dark chocolate on the edges and around the eye, then use a toothpick to make hash marks. Refrigerate until set and enjoy!
