If you want to make this using the AeroPress, use 3 scoops of ground coffee and fill up to the 3 line before pressing. Then add water to raise to 10 oz.
Combine 1/3 the coffee with 2/3 of the sweetened condensed milk and mix well.
Divide this mixture evenly into the molds.
Place in freezer for 1 hour or until it is barely frozen.
Combine the remaining 2/3 of the coffee with the remaining 1/3 of the sweetened condensed milk and mix.
Use this mixture to fill the remainder of each mold and insert sticks.
Place in freezer for 3-5 hours.
