Put some ice cubes in a steel bowl or plastic bag and crush them into small pieces with a cocktail muddler.
Place the crushed ice in the jug of an electric blender.
Note: You can make Mudslide Cocktail with a common cocktail shaker as well, but you have to shake it vigorously for a longer period of time.
Next add 250ml of thin cream, 250ml of Irish Cream liqueur, 60ml of properly chilled vodka, and 60ml of Kahlua liqueur into the blender.
Note: If you want to make a stronger tasting Mudslide Cocktail, then increase the quantity of vodka. On the other hand, if you want the cocktail a little lighter, then add a little more Irish cream or Kahlua liqueur.
Seal the electric blender properly and switch it on at medium speed to blend the ingredients.
Continue blending until the chocolate ice cream mixes with rest of the ingredients and forms a thick smooth cocktail with a foamy surface.
Remove the jug of the blender and set it aside until the bubbles on the surface of the cocktail settle down.
Meanwhile, rim your cocktail glass. You can use any stylish cocktail glass that you like. Place some finely crushed chocolate sprinkles in a plate. Cut a lemon into two and squeeze the juice of one of the slices. Dip the rim of your cocktail glass into lemon juice and then again dip it in the chocolate sprinkles. You can replace the chocolate sprinkles with sugar.
Note: This step is optional. You can either use a simple cocktail glass or can garnish it with a fruit wedge or some broken chocolate pieces.
Now, remove the lid of the blender and pour the cocktail into the glass.
Your Mudslide Cocktail is now ready to enjoy. You can top it with chocolate milk or milk in order to make it become a long drink.
Now, if you are craving to have a lip spanking creamy cocktail then simply convert this simple Mudslide Cocktail into a Frozen Mudslide Cocktail. The only thing you have to do is, add in 8 scoops of ice cream of your choice to the above mentioned ingredients. Once you pour the Frozen Mudslide Cocktail into the cocktail glass, top it with whipped cream and serve straight up. This cocktail is frequently called as milkshake for adults as it contains alcoholic ingredients.
