These muffins take the premise of the double chocolate muffin and twist it around. Chunks of roasted cocoa nibs in the streusel give you the essential bitterness of chocolate while chocolate bits in the crumb add sweet punch.
'cocoa nibs' on Serious Eats
Spending as much time around chocolate and candy as I do has changed my threshold level for it. Not to say I don't still love both with a fiery passion and crave them all the time (I totally do) but the ferocious sort of "I-must-put-this-in-my-face-right-now-as-fast-as-I-possibly-can" feeling has lessened somewhat over the years. Not so with cookies.
I added nibs to this recipe adapted from The Essence of Chocolate; but you could also use any finely chopped nut or fruit you like.
They're showing up in more places than ever: baked in fancy restaurant desserts, folded into ice cream, and even lining the shelves of grocery stores. But their exact origin and nature is still something of a mystery to many people. I'm talking about cocoa nibs. What are they? Bits of fermented, dried, roasted and crushed cacao bean. They're extremely good for you, and have an intense chocolatey taste, but aren't sweet at all.
After baking up a batch I realized that there was nothing embarrassing about these cookies, save for their unfortunate name. The dough is not that different from the Toll House version, just a bit more brown sugar and less white. The cacao nibs and ground coffee lend a wonderfully adult bitter richness. And the extended chill in the fridge makes for cookies that are nice and crunchy on the outside, but chewy and just underdone enough in the center to make them a guilty pleasure.
