Butterscotch Rice Krispies® Bars
This is what I grew up with in lieu of 'scotcheroos'. They are simpler to make and pack a much richer flavor which means when I bite into similar recipes (hoping for this flavor), I am disappointed and want my homemade version!
If it is crumbling when you cut it, it may be too cold (if you chilled it in the freezer or outside in the winter), and you may need to warm up a bit. It is not as chewy as other recipes.
