Ingredients

  • 3 Tbsp (24g) all-purpose flour packed and leveled*
  • ¼ tsp baking powder
  • 1 Tbsp (15ml) pure maple syrup**
  • 2 Tbsp (30ml) creamy peanut butter
  • 4 Tbsp (60ml) milk of choice***
  • 1 tsp avocado oil optional
  • Pinch sea salt
Optional Additions:
  • 1 to 2 Tbsp semi-sweet chocolate chips
  • ¼ tsp pure vanilla extract
  • ¼ tsp ground cinnamon

Instructions

    Cup of Yum
  1. Add all of the ingredients to a microwave safe mug (or a small bowl or measuring cup) and mix until a smooth cake batter forms and all the lumps of flour have dissolved. There is no need to separate the wet ingredients from the dry ingredients as everything should mix together very easily. If you’d like, sprinkle extra chocolate chips on top of the cake batter.
  2. Microwave for 60 to 75 seconds (on the regular high setting), or until the center of the cake has set up. I recommend starting with 60 seconds, then adding 8-15 seconds if the cake looks like it still needs more time.
  3. Dig in and enjoy! For a special treat, serve the mug cake with a small scoop of vanilla ice cream and a glass of milk.

  • The exact cooking time depends on the strength of your microwave; however, most microwaves will perform excellently under this 60-75 second timeframe.
  • An easy way of telling whether or not a treat is fully cooked is to take the internal temperature. Simply insert a digital thermometer into the center of the cake. If the cake reads 190 degrees Fahrenheit or higher, it is fully cooked. The optimal temperature range for treats like this is 190-200 degrees F.
