I have a recipe for brownies made with German chocolate cake mix, chocolate chips and caramels that I always make ahead of time. They’re not nearly as good the day they come out of the oven.
Oh. My. God.
drooll
PUMPKIN PIE!
Gumbo most definately made a day ahead. Or better yet make a large batch and freeze the left overs,aaaa eeee!!!
Cold fried chicken…Mmmmmmm…cold fried chicken [drool]…
Beef stroganoffand my homemade cheeseball.
My homemade tuna salad usually tastes much better the second day. Same goes for my world-famous spaghetti sauce and my husband’s marvelous chili.
I also think roast beef is great the day after…providing there is any left. Which is just about never.
Oh yeah! Red beans and rice. In fact, I don’t really like them very much the first day. No matter how you spice them up, they always taste bland right after they’re made. The second day they are perfect. Of course, I always have to toss a little more tobasco sauce on mine…just for improving upon the perfection. 
Egg salad and Deviled Eggs.
Gives the mayo or whatever you put in it time to mix and meld together… mmmm.
Banana bread.
anything italian or chienese is usually better the second day
Also anything diary based like cheese is good also
