Hello everyone, I will be making a 3-dimensional train cake for my son's and daughter's birthdays.  I have it all planned out and need to bake several pound cake in loaf pans.  The engine and the train cars will be carved out of those loaves.  I am wondering if someone has a recipe for pound cake that does not crumble or "melt in your mouth" but stays together well.  It can be another type of batter, I just need something firm and delicious.  I might make several flavors (chocolate, vanilla, whatever), so toddler-friendly variations would be fine.

Thank you in advance.
