Soak dates in warm water for at least 10 minutes to soften.

In a food processor, add cashews, macadamias, and oats. Process until mixture reaches a fine, crumbly texture.

Add softened dates, peppermint extract, cocoa powder, and maple syrup to food processor and blend until fully incorporated.

Pinch off about 1 Tbsp of the mixture and roll into a ball. Continue with remaining mixture. This should yield about 14 bites.

Place each bite on a sheet of wax paper. Drizzle bites with dark chocolate and let sit until chocolate is fully set.
