canned frosting to bind the brownie/cake together.
i did not. so long as your brownies are good and moist and fairly fresh from the oven they should compact well.
what kind of molds did you use for these brownie bites? please post link? thanks.
this post is nearly 5 years old, so i don’t have the information you desire. but if you do a search for chocolate molds, i’m sure you could find something that would work well.
