Pit the dates and place on a parchment lined or silpat lined baking sheet or large plate.
Scoop some of the peanut butter into the dates, then stick a peanut into each of the dates. Repeat until all dates are stuffed.
Place the chopped chocolate and coconut oil into a medium microwave-safe bowl and place in the microwave for 30 seconds. Remove and stir well, then place back into the microwave for another 30 seconds, stir and remove. Take care not to over microwave the mixture. Usually 1-2 times will work, with stirring in between.
Dunk (or drizzle) the date into the melted chocolate, then place back on the lined baking sheet. Repeat with the rest of the dates. If there is any leftover chocolate, I usually drizzle the remaining over the dates then sprinkle on chopped peanuts.
Place into the freezer and let harden, for 1 hour. Remove and place in a freezer-safe container to enjoy!
