What makes this frosting crispy and crunchy?
Two things: crispy rice cereal (light, snappy crunch) and toasted nuts (deeper, roasty crunch). They get folded in after the frosting is finished so they do not soften.
Can I use Dutch process cocoa?
Yes. Dutch process cocoa gives a darker color and smoother chocolate vibe. Natural cocoa tastes a bit sharper and more classic. Use what you have.
Can I make it without nuts?
Absolutely. Skip the nuts and add more cereal, or use crushed pretzels or crushed waffle cone pieces for a fun twist.
What is toasted sugar, and do I need it?
You do not need it. It is optional, and this frosting still rules without it. Toasted sugar is granulated sugar baked low and slow in the oven until it tastes warm and slightly caramel-ish (it is not the same as caramelizing sugar on the stove). If you already have some, add it. If not, skip it and do not worry about it.
Why is my frosting grainy?
Most commonly: the powdered sugar was not sifted, or the frosting was too cold and never fully creamed. Let the butter soften properly and beat it until fluffy before adding sugar. If it is still grainy, keep mixing for a minute or two and add 1 teaspoon milk.
How do I make it less sweet?
Add a bit more salt (start with 1/8 teaspoon) and use unsweetened chocolate instead of semisweet. You can also add 1 to 2 teaspoons extra cocoa.
Can I pipe this frosting?
You can, but the crunchy bits can clog smaller tips. Use a large open star or round tip, or spread it on with a spatula for stress-free results.
