This is such a great recipe! I am not into "spice" so I use mild salsa and just a little bit of hot sauce. This makes a great dip with tortilla chips and it's very creamy. Everyone loves the taste and likes that it's healthy too!
I made two batches of these and thought they turned out really well and tasted great. One batch I tried reducing the flour to 1 3/4 cup and they didn't hold their "ball" shape. So I personally can't recommend reducing the flour. I think it depends on how you measure your flour (I spoon the flour into the measuring cup rather than scooping it out of the container). I wouldn't recommend using milk or egg, this will alter the chemistry of the recipe. Make sure your butter is VERY soft before you start and use a smaller amount of dough to cover each kiss. Don't overcrowd the cookie sheet, they won't rise but they will spread just a little bit. I think these will go over well at my cookie exchange!
