Ellyn, do you want to do a mash-up with all three of these? I'm intrigued! Let's brainstorm it!
I'm thinking of something like a "naked cake". First, there's the turtle pie base, which is an 8-ounce pack of cream cheese softened and blended with maybe half a cup of sugar (or more), half a cup of peanut butter, half a cup of cocoa (or less), two cups of cream to stretch it out, and maybe a teaspoon of vanilla if it doesn't emulsify (I learned this trick from making cream-cheese based clotted cream.)
The turtle pie filling above is basically no-bake. An easier way would be to use Jell-O's instant chocolate pudding that it mixes with milk.
Next, just making the bran to add to a basic banana bread recipe: soak one cup of bran in buttermilk, or substitute that soaking solution with half a cup of vinegar and half a cup of milk, for at least 10 minutes.
In a separate bowl, meanwhile, combine the standard banana bread ingredients: 1 cup sugar, 1/2 cup butter, 1 large egg, the mashed bananas, 2 teaspoons baking powder, 1 teaspoon of salt, and a cup of flour (which is making me think that I may be putting too much bran...but oh well! Brainstorming!)
Mix in the bran, and the pecan nuts or walnuts, of course...the turtle pie filling has none, and while banana bran bread can do well enough without nuts, it's not a turtle pie without them.
Pre-heat oven to 350ºF (that's about 175ºC), pour banana bread into cake pans, and bake until done. Either by using shallow filling in the cake pans, or a thin cake-leveler, get your layers (after they've cooled down!) and spread the turtle pie filling in between. I just hope the weight of the banana bread doesn't squish all the filling out!
Sounds excellent! Do you have a good recipe for bolo de banana? I've never tried it, but just did a quick google and it looks delicious!
I haven't decided on a recipe to go by yet, although I'm seriously considering plantains in caramelized condensed milk, and just a box of vanilla cake or butter cake...just to get a feel of making it! Rum cake might be even better.
