Begin the recipe by grabbing a blender and measuring out the three ingredients. When measuring out the ice cream and peanut butter, be sure to pack it in.
Add ¼ cup milk, 2 ¼ cups vanilla ice cream, and 2 tablespoons of peanut butter into the blender. Blend on medium speed until completely blended and smooth.
Pour the milkshake into a serving glass for one and Enjoy!
Pour the milkshake into two 8-ounce glasses, add straws and serve immediately or pop the shake into the freezer for 10 to 15 minutes if you like it firmer.
