Core and slice the apples into rounds. Cut out the center with a spoon or paring knife.
Place apples in a bowl and cover with water. Squeeze the lime into the water and allow to soak for 15 minutes. Remove and dry completely with paper towels or clean kitchen towels. Set aside.
Add the chocolate to a microwave safe bowl and top with oil. Melt the chocolate in 30 second intervals until completely melted. Don’t overheat. Alternatively, you can use a double boiler on the stove.
Dip the apples in the chocolate, one at a time, and turn until covered. Remove and set on a plate covered in wax paper. Once all apples are coated in chocolate, place the plate in the refrigerator to set for about 10 minutes.
Serve and enjoy!
