OK, this is my hands-down favorite so far. It's like crack to pumpkin lovers. But the exact recipe has eluded me so far. Seems like it would be easy to replicate - just add pumpkin and the spices to ice cream, but what you end up with is a milk shake or a smoothie, which doesn't taste quite right. Someone smarter than me looked on the Dairy Queen website for the ingredients and came up with this list: pumpkin pie mix, ice cream and shortbread cookies. I have never bought pumpkin pie mix and actually thought it was runny, but it's not. You have to add the milk and eggs to it to make a pie. It looks exactly like pumpkin puree except darker in color. The shortbread cookies didn't sound right to me either, so we used blonde Oreos.
I actually used soft serve from Dairy Queen, but any ice cream would work. The first batch I used the blender, but it mashed the cookies too small; the second batch I used a hand mixer and liked the results better. I didn't measure the ingredients but a one to three ratio with the mix and ice cream is about right. Cookies to taste. So easy but so good.
