Fill a piping bag with a wide plain tip with 2 cups dulce de leche or filling of your choice.
Have ready a wire rack with 24 small Oreo cookies.
Starting in the middle, squeeze the dulce de leche until it almost reaches the edges, and then keep squeezing as you lift the piping bag until you reach the desired height.
Melt 6 ounces white chocolate in the microwave or over a pan of hot water.
If the filling is soft, put the cones in the freezer or refrigerator until they are firm enough to turn upside down.
Dip them upside down into the melted chocolate until completely coated.
Let the excess drip and place them on the wire rack.
Let cool until you can place 48 candy eyes without them falling because the chocolate is too warm.
Let dry completely until the shell is firm before eating. You can put them in the refrigerator to speed up the process.
Store at room temperature or in the fridge.
