Dirty Dr. Pepper Floats

Dr. Pepper soda (for a healthier treat use Dr. Pepper 10 - it's our favorite! But any Dr. Pepper soda will work), chilled

sweetened coconut milk (not condensed - you can find coconut milk in the Asian section at your grocery store)

coconut extract

limeade (I used Simply Limeade but you could use another brand or make fresh limeade as well)

optional: limes for garnish
