Simple proportions, simple flavors.

This sweet, bourbon-based cocktail has a creamy/frothy consistency due to the pineapple juice.

1.0 oz Bourbon
1.0 oz Triple Sec
1.0 oz Creme de Banana
1.0 oz Pineapple Juice

Into a shaker with ice, add all of the ingredients. Shake, then strain into a glass with some of the ice.
