A while ago, we were looking in our freezer and found a few almost-empty containers of ice cream that we thought we should use up. They were starting to get that frozen crystallized look--not super appetizing, so I just threw them together and blended up a milkshake! It was so good, I did it again a couple nights later! And since then, I've kept going back to it as a really yummy, incredibly easy dessert to make. Here are the approximate measurements. What I did turned out a little runny, so you can adjust how much milk you add to it based on whether you want it drinkable or "spoonable".
1-1.5 cups of vanilla ice cream (we had vanilla with a chocolate swirl in it...)
1-1.5 cups of chocolate ice cream
3/4 cups-1 cup of peanut butter
1/2-1 cup of milk
For some variety, you can leave out the peanut butter and add 1/4-1/2 cup of berries, frozen or not.
To really make things exciting, add 1/4 cup of Irish Creme liqueur before you blend it up.
Since I have an immersion blender, I just put everything in a container that I have and blended it up--this turned out to be perfect for two people! It's so easy and so delicious!
