The Best Coconut Key Lime Pie Smoothie (High Protein!)
This dreamy Coconut Key Lime Pie Smoothie tastes like sipping your favorite tropical dessert through a straw! Creamy coconut milk meets tangy key lime and vanilla for authentic pie flavor, while Greek yogurt sneaks in 16g of protein to keep you satisfied all morning. Ready in just 5 minutes with naturally sweet ingredients, no refined sugar needed.
Ingredients
- 1 cup full-fat coconut milk canned, well-shaken
- 1 cup plain Greek yogurt full-fat or 2%
- 1 large frozen banana about 1 cup sliced
- 3 tablespoons fresh key lime juice or 2 tablespoons regular lime juice
- 1 tablespoon honey or maple syrup
- 1 teaspoon pure vanilla extract
- ½ cup ice cubes optional, for extra thickness
- Pinch of sea salt optional
Optional Toppings:
- Whipped cream or coconut cream
- Graham cracker crumbs
- Fresh lime zest
- Toasted coconut flakes
Instructions
- Make sure your banana is completely frozen (at least 4 hours or overnight). Shake the coconut milk can well before opening. Juice your limes and remove any seeds.
- Add ingredients to your blender in this order: coconut milk, Greek yogurt, frozen banana chunks, lime juice, honey, and vanilla. This layering helps everything blend smoothly without leaving chunks at the bottom.
- Blend on low speed first, then increase to high. Blend for 45-60 seconds until completely smooth with no banana chunks remaining. The mixture should be thick enough to hold soft peaks, similar to soft-serve ice cream.
- Taste and adjust to your preference. Add more honey if too tart, more lime juice for extra tang, or a few tablespoons of coconut milk if too thick. For a smoothie bowl consistency, add ½ cup ice and blend again.
- Pour into glasses or bowls immediately and serve. Top with whipped cream, graham cracker crumbs, lime zest, or toasted coconut if desired. Rinse blender with hot water right away to prevent coconut and banana from hardening.
Notes
Protein Boost: Add 1 scoop vanilla protein powder (add after liquids, before frozen banana to prevent clumping). This increases protein to 30+ grams per serving.
Storage: This smoothie is best enjoyed fresh. For meal prep, portion dry ingredients (frozen banana, shredded coconut, any add-ins) into freezer bags. Store liquids in the fridge. Blend fresh each morning for best texture.
Texture Tips: Frozen banana is crucial for creamy thickness, don't substitute with ice as your main thickener. If smoothie turns out watery, your banana wasn't frozen enough or you used light coconut milk instead of full-fat.
Lime Variations: Key limes are more floral but also more tart. If using regular Persian limes, start with 2 tablespoons juice and adjust to taste. Add a tiny squeeze of lemon juice for complexity.
