Add all ingredients (except for toppings) to a high-speed blender. Blend until smooth (mixture should be extremely thick). If your blender is having trouble, stop and stir with spoon. Repeat until evenly blended.
Pour into bowl and have fun with your toppings!
*Tips: Use a chilled bowl to keep the smoothie frozen longer. Have your toppings sliced and diced and ready to go before blending!
