Bananas create a perfectly creamy base, which is beneficial for smoothie bowls as well. Simply adding a banana will instantly make your smoothie thicker, but you can also use a frozen banana for a smoothie recipe that’s even more ice cream-esque and frostier. Mangos are another “creamy” fruit that creates a thick, almost “fluffy” texture. Avocados easily enhance the viscosity of a smoothie and leave it with an almost velvety quality. A little bit of yogurt can help improve the textural balance of a smoothie. Chia seeds are master thickeners, often used in all kinds of recipes for their ability to gel up when soaked in water. Adding a spoonful or two of organic chia seeds to a smoothie will thicken it substantially within 10-15 minutes. Cooked sweet potatoes, yams and winter squashes like pumpkin can instantly enhance the makeup of a smoothie while keeping the sugar and calorie content low. Frozen fruit and vegetables can quickly make your smoothies thicker, try adding in a half to a full cup of frozen berries or frozen tropical fruit. Ice can turn a watery creation into a frosty blend in no time.
