While this isn't a specific "recipe", Yonana creations are one of the things we enjoy most. The Yonana machine can be purcahsed at Bed Bath & Beyond or on-line. It turns frozen bananas and other frozen fruits into soft serve "ice creams". Mine did come with a recipe book, but I'm not sure if the newer models do since most of the recipes are on line. There are also numerous you tube videos of various creations. You do not HAVE to use bananas, although they are delicious for great banana splits.
Banana Split
Frozen Yonana ice cream - made with bananas only
Top with chopped pineapple, strawberries, and easy chocolate sauce:
Easy Chocolate Sauce:
1/2 cup dates
1/4 cup cacao powder (or cocoa)
Place dates in a bowl of water to soften. Remove from water and place in a food processor with the cacao powder, and enough water to reach desired syrupy consistency. Coconut water also works well.
