In a large mixing bowl, combine the rolled oats, almond butter, and honey (or maple syrup). Stir until well blended.
Add in the chopped dried cranberries, almond slices, vanilla extract, ground cinnamon, and sea salt. Mix thoroughly until all ingredients are evenly distributed.
Using your hands, scoop out about a tablespoon of the mixture and roll it into a ball. Repeat this process until all the mixture is shaped into energy balls.
Place the balls on a parchment-lined baking sheet or plate.
Refrigerate the energy balls for at least 30 minutes to firm up.
Store in an airtight container in the fridge for up to 1 week or freeze for longer storage.
Notes
Arrange the energy balls in a small bowl or snack container, and sprinkle extra almond slices around them for an appealing presentation.
