Place dark rum, light rum, lime juice, orange juice, and bananas into blender. Top with ice.
Blend until smooth and creamy.
Pour into chilled glasses.
Notes
To freeze bananas - cut them into ¼'s and place on a cookie sheet. Once frozen, scoop them into a ziplock bag and store in the freezer. When a recipe calls for one banana, just get 4 parts. Lime juice - always use fresh squeezed. Bottled lacks the freshness. Homemade Vanilla Infused Rum - would also be great with this recipe!
