Can I just say: NOM NOM NOM. Okay. Now that's out of the way, I made some brownies.
These are my latest variation on the Best Cocoa Brownies from Smitten Kitchen. I followed the recipe mostly, but was forced to put this into variation territory when I ran out of cocoa powder part-way through. To make up for having less cocoa powder than required, I substituted some Orange Hot Chocolate powder I had - a few heaping tablespoons worth. (Whittard's, if anyone's interested). Since this has sugar in it already, I reduced the sugar I added separately. I also used less butter because I ran out of that as well - but not significantly less, maybe 10 g less? No noticeable effect.
Result: moist, dense brownies with a slight orange-y taste. Not overwhelming, but quite pleasant. In the future, I may try this with orange zest instead of orange hot-chocolate. I bet that would taste even better.
