We set out to dress up this kids' favorite for Valentine's Day. While we were at it, we put the back-of-the-box recipe under the test kitchen microscope.
Why This Recipe Works
We tweaked the cereal-to-marshmallow ratio our original Double Fluffer-Nutter Treats to produce creamier, richer treats, and added a bit of vanilla extract and salt (both missing from the original recipe) for flavor. For thicker, more substantial squares, we patted the mixture into an 8-inch square pan instead of the usual 13- by 9-inch pan. To incorporate the flavors of chocolate and peanut butter, we stirred in dry-roasted peanuts. For even more peanut butter flavor, we melted peanut butter chips with the butter and marshmallows and drizzled melted peanut butter chips on top.
