Combine the butter and powdered sugar and cream with a hand mixer at medium speed for 2 minutes.
Add the rolled oats, cocoa powder, coffee and vanilla and mix again until combined.
With slightly wet hands divide the mixture into 13 balls, rolling them between the palms of your hands. I weighed mine at 36 g each.
Pour the shredded coconut into a shallow bowl and toss each ball in it until fully coated. Transfer chocolate balls to a serving plate and serve.
Notes
The nutrition information provided is per single ball if making them of the recommended size and is only an estimate.
Salted butter is recommended as the addition of salt balances in flavour the high sugar content. Add a pinch of salt if using unsalted.
Chocolate oatmeal balls taste best at room temperature. Take them out of the fridge 30 minutes before serving.
If making this recipe in a really hot room temperature you may consider chilling the balls 30 minutes before serving, to firm them up a little.
Chocolate oatmeal balls are fine to keep at room temperature for a couple of days. Refrigerated they will keep for up to 3 weeks. Freeze up to 6 months. Thaw before consuming.
