I have never made these and want to make these for a get-together. I have some questions for those that have made these: 1. Can they be made ahead? Can I make the brownie cups and the filling the night before and keep them separate and just fill them the night before, or does the filling not hold up overnight in a container?? 2. Can I use the brownie part of the Truffle Brownie Cups instead of the brownie part of these? Or is there a big difference in taste? (I know the Truffle one makes half as many as this one.) 3. Any suggestions on other toppings besides Strawberries? I am looking for something other than fruit. I cannot depend on my store to not have moldy strawberries when I need them. Thanks!
