Sonic Drive-In Peanut Butter Shake

These easy-to-make milkshake clones from Sonic's fountain are no longer available at the 3,342-unit drive-in burger chain, but we'll always have a clone. The straight peanut butter version is crazy delicious if you're into peanut butter. And when you add a little fudge to the recipe for the second hack here, you've got what tastes like a creamy Reese's Peanut Butter Cup. Good stuff, man.

  1. Combine the ingredients for the shake of your choice in a blender. Pack the ice cream into the measuring cup when you measure it out. Blend everything on medium speed until smooth.
  
  2. Pour the shake into a 16-ounce glass, add a straw, and serve. Pop the shake into the freezer for 10 to 15 minutes to firm it up if it's too runny.
