  • Hand mixer
  • 12-Muffin tray
  • Cupcake liners
  • Piping bag and tip



  • 290 g 5 large eggs
  • 240 g Unsweetened peanut butter 1 cup
  • 100 g Erythritol 1/2 cup
  • 45 ml Freshly squeezed lemon 3 tablespoons
  • 30 ml Unsweetened almond milk 2 tablespoons
  • 5 ml Unsweetened vanilla extract 1 teaspoon
  • 2 g Baking soda 1/4 teaspoon
  • 2 g Salt 1/4 teaspoon


  • 200 g Softened butter 7/8 cup
  • 180 g Unsweetened peanut butter 3/4 cup
  • 100 g Powdered erythritol
  • 5 ml Unsweetened vanilla extract 1 teaspoon
  • 1 g Salt 1/8 teaspoon


  • Preheat the oven to 170℃/338 ℉.
  • Put all the ingredients for the cake together, into a big bowl.
  • With a hand mixer, whisk until well combinend. 
  • Mix with a spatula at the end, to ensure that there is no unmixed part left.
  • Line the 12 muffin baking tray with cupcake liners.
  • Divide the batter equally into the tray. I used 1/4 cup (60ml ) to pour into each, then divided the remained batter by eyeballing.
  • To settle the batter, tap the tray few times before putting it in the oven.
  • Bake in the preheated oven for ca. 20 minutes.
  • Insert a toothpick in the middle of a cupcake and when it comes out clearly, it is baked.
  • Take the cupcakes out of the oven, after they are cooled enough to be touched, put them on a rack to cool.
  • Meanwhile, mix all the ingredietns for the frosting into a large bowl.
  • With a hand mixer, whisk until well combined.
  • Use a spatula occasionally to mix the unreached part.
  • When stiff peaks form, it's ready.
  • Put it in the fridge until needed.
  • When the cupcakes are comletely cooled, they can be frosted.
  • By using a piping bag with a tip of choice, squeeze the frosting onto the cupcakes. 
  • Sprinkle some chopped almonds to garnish.
  • Enjoy!
