DISCLAIMER: This recipe is for humans not dogs!

My dad’s girlfriend’s daughter, Qing, was feeling pretty sick this weekend, so I went over on Friday night to hang out and baked something while I was there. She wanted brownies, and I tried to think of a fun twist on them. I really like mousse, and I decided to make an orange mousse and make them a bit Halloween-themed.

They turned outΒ super chocolate-y with a nice light fruity middle. I made the bottom brownie layer pretty thin because I wanted plenty of room for the mousse. It made a nice, chewy, fudgy base. The top ganache layer added another aspect of chocolate and a nice color contrast with the orange mousse. Overall, it was a pretty simple recipe that led to a good result. Also, credit goes to Qing for the dog photos and helping prepare the ingredients.

A couple notes:

  1. Be gentle when making the mousse. If you mix too vigorously, you’ll deflate it.
  2. Make sure that the brownies and ganache areΒ cold when you’re assembling or you’ll melt the mousse.
