I am starting to think of ideas for my son's birthday cake, Andy's room from toy story. I am going to make the bed, toy box and block letters out of fruity pebbles(my son is gluten free so I can't use rice krispies) covered in MMF. My problem lies in how to do the sheet cake for the floor. I plan on using gluten free flour but can't decide what type of cake would be best and if I should slice it in half and add a filling. He wants a pink cake, doesn't mean strawberry just has to be pink. Would pound cake work with a filling and then covered in MMF with the bed and decorations on top?? Could I add strawberry jello mix to the pound cake batter to make it pink and add some extra flavor??? What kind of filling would I use since I can't put the cake in the fridge??

Thanks in advance for the help

my daughter is gluten free also....I find the gluten free flour mixture has to be perfect or you will get a rock or a brownie....I actually use the Betty Crocker gluten free mixes, they are perfect and moist - 1 box only does a 9" cake though.....I use wilton gel color in my cakes to add color, I just did a pink marble that came out really cute.....you can use buttercream frosting between the layers - which does not need refrigeration - I have a great recipe that stands up pretty well to the heat of the kitchen shelf...you could also melt pink mini marshmallows for the filling, which kids will love - just be sure to use a syrup treatment on the layers so it doesn't get smooshy....hopefully helpful, Tedra.
