Plug in the cake pop maker to preheat it. In a medium bowl, combine the butter and brown sugar.
Add the rest of the ingredients (except for the powdered sugar) and mix until well combined.
Add the batter to a piping bag to make it easier to add to the cake pop maker, or you can use a teaspoon. Fill the cake pop maker holes until almost full (leaving about 1mm on top).
Close the lid and bake in the cake pop maker for 4 minutes, or until golden brown and a toothpick comes out clean from the center.
Remove from cake pop maker and let them cool for a few minutes. Repeat with remaining batter.
Sprinkle with powdered sugar and serve. You can also pop them on treat sticks if desired.
Notes
There is no need to stick the treat sticks to the cake ball using melted chocolate because they don't have a coating, which keeps them light.
Store in an airtight container in a cool, dry place like your cupboard or pantry for up to 1 week.
