I was at the grocery store over the weekend and they had a sale on some DH orange cakemix. It was $.75 a box, buy one get one free. So..now I have some orange cakemix and I don't know what to do with it. I've never made an orange flavored cake before. What can I do with it other than make it per directions and frost/decorate. I was thinking of putting chocolate as a filler and buttercreme icing. Is there anything I can/should add to make it really tasty?

Chocolate and orange are great together. you can also use mocha, vanilla buttercream.

Mix some lemon &/or orange zest into the batter &/or b'cream.
Use pineapple juice as the liquid. Can add crushed pineapple too - doesn't take much - about 1/3 cup is plenty.
Add mini cho chips to batter

Yumm...those all sound like great ideas. I'm really leaning to the mini choc chip idea. I have a box of instant vanilla pudding that has mini chips in it. Do you think that would be ok to add to the cake mix? I've never added pudding to a cake mix before and keep hearing ya'll talk about it. Do you have to add any extra water/oil/egg to it if you add pudding? Is it instant pudding? I'm VERY new at using something other than straight box mix.
