On a cookie sheet, lay out the pretzels in rows. (I recommend doing them in 2-3 batches to make it easier)
Unwrap all rolo candies and place one on each pretzel.
Preheat oven to 250 degrees F.
Cut the apple into bite size pieces then stick a toothpick through it. Set aside.
Bake the pretzels for 3-4 minutes.
Quickly stick the apples on top of the rolos and sprinkle toffee bits. You may need to push some toffee pieces into the melted chocolate to stick.
Stick in fridge for 20-30 minutes then push the toothpicks all the way through the bottom of the pretzels. Serve!
Notes
Note these should be made the day of 1-3 hours before you serve or the apples will start to "sweat."If you don't want the apples to turn brown, you can soak them in lemon juice or sprite then completely dry them off before putting them on the rolos.
