That classic yummy vanilla cake flavor we all know and love without any of the guilt. The perfect healthier sweet treat for a celebration!
  • 1 frozen large banana, as ripe as possible (peel before freezing)
  • 1/2 to 2/3 cup unsweetened vanilla almond milk or milk of choice Use more or less milk, depending on desired thickness.*
  • 1 scoop vanilla protein powder**
  • 1 tablespoon coconut flour
  • 1/8 teaspoon butter flavoring you can find this with spices and extracts
  • 1/8 teaspoon almond extract
  • 1/4 teaspoon baking soda or baking powder
  • pinch of salt believe it or not, it really lets that b-day cake flavor shine through
  • Optional: handful of sprinkles
  • 1-2 cups ice cubes use more or less ice, depending on how slushie you prefer your smoothies
  1. Blend all ingredients together in your Blendtec or other high-speed blender. Add some sprinkles, before blending, and then throw some more on top!
  2. To get the extra sprinkles on the rim and inside of the glass, I added honey around the rim and fingerprints of honey on the inside of the glass and then pressed sprinkles to the dots of honey on the inside. For the rim, I added sprinkles to a bowl and then turned the glass upside down in the bowl to allow sprinkles to stick to the rim.
Recipe Notes

*If you're not a banana fan, try using 1/2 a large avocado to replace the banana. I've heard it tastes great, but it will tint your smoothie green.
**Feel free to leave out the vanilla protein powder, but I think it helps to give this smoothie a delicious b-day cake flavor. Perfect Fit Protein Powder has a lovely flavor and contains 15g protein, 100 calories, 1.5g fat, 5g total carbs, 0g sugar.
***If you prefer smoothies in a bowl, reduce milk or add a pinch of xantham guar gum.
****FYI: Butter flavoring is a vegan product.
*****For added nutrition, add a handful of baby spinach. It will make the smoothie green, but will not change the taste at all.
******Nutritional information calculated using unsweetened vanilla almond milk as the milk of choice and Perfect Fit Vanilla Protein Powder.
