Semi sweet or milk chocolate chips
Mini marshmallows
Dry roasted unsalted peanuts

Mini muffin pans
Mini paper muffin cups

Melt chocolate chips in a double boiler.
Place 5 marshmallows in each muffin well.
Add peanuts (enough to finish filling each well, don't overfill).
Carefully add melted chocolate to each well using a knife to work the chocolate to the bottom of the wells (don't stir the chocolate in or you will melt the marshmallows).

Tap muffin pan on a counter or table a few times to work out air bubbles.
Place pan in freezer till candy has hardened.

Once candy has hardened take the pan out of the freezer and hit pan on a hard surface to break candies out of the wells. It will take a bit of banging to get the candy out. if the candy is stuck and starts to warm refreeze or place in a warm oven to melt the sides a little. Once warmed run a knife around the edge to get the candies out. Place the candies in paper muffin cups and place on a cookie sheet.
Warm the candies in a warm oven just a few seconds to allow the paper to stick to the bottom of the candy. Refreeze or refridgerate to reharden the candy.

Helpful hints:

I did not put in a measurement of chocolate chips because depending on how many you plan to make you will need to keep adding more chocolate. Usually 1 12 oz bag will make 1 dozen candies.
