Root Beer Float with Homemade Hot Fudge

For the hot fudge:
Combine sugar, cocoa, salt, and flour in a bowl or pot over a double boiler.

In a separate pan, bring water or milk to a boil. Gradually add hot liquid to sugar mixture. Stir constantly over the double boiler until mixture thickens.

Once it has reached the desired thickness, remove from heat and stir in butter and vanilla. Serve immediately if you would like a thinner sauce, or let it sit at room temperature for an hour to thicken. Store in the refrigerator.

To assemble your floats:
Scoop equal amounts of ice cream into two glasses. Top with a bit of hot fudge, then pour in the root beer. Drizzle a little more hot fudge over top. Devour. Die. Go to heaven.
