Ingredients
For 2 servings:
- 1 cup coconut milk (canned or carton, unsweetened or lightly sweetened)
- 1 medium banana, frozen for extra creaminess
- 3 tablespoons fresh Key lime juice (or regular lime juice if unavailable)
- 2 tablespoons Greek yogurt or coconut yogurt
- 1–2 tablespoons honey, maple syrup, or agave (adjust to taste)
- ½ teaspoon vanilla extract
- ¼ teaspoon coconut extract (optional for extra coconut flavor)
- ¼ cup graham cracker crumbs (optional, for a crust flavor)
- Ice cubes (optional, for a thicker smoothie)
- Garnish: whipped cream, lime zest, toasted coconut flakes, or graham cracker crumbs
Step-by-Step Instructions
Step 1: Prepare Ingredients
If using a fresh banana, peel and slice it, then freeze for at least 1 hour for a creamy texture. Juice the Key limes and have your coconut milk and yogurt ready.
Step 2: Blend the Smoothie
In a blender, combine coconut milk, frozen banana, Key lime juice, Greek or coconut yogurt, honey or maple syrup, vanilla extract, and coconut extract (if using). Blend until smooth and creamy.
Step 3: Add Graham Cracker Flavor (Optional)
If you want a true Key lime pie experience, add graham cracker crumbs and blend for an additional 10–15 seconds until incorporated.
Step 4: Adjust Consistency
Add ice cubes if you prefer a thicker smoothie, or a splash of coconut milk to thin it out. Blend again until smooth.
Step 5: Serve and Garnish
Pour the smoothie into glasses and top with whipped cream, lime zest, toasted coconut flakes, or extra graham cracker crumbs. Serve immediately and enjoy!
Tips for Success
- Frozen Banana: Using a frozen banana gives the smoothie a creamy, milkshake-like texture.
- Sweetness: Adjust honey or maple syrup to your preference. Key limes are more tart than regular limes, so taste before adding sweetener.
- Coconut Options: Use canned coconut milk for richness, or carton coconut milk for a lighter version.
- Smoothie Bowl Variation: Pour into a bowl and top with granola, fresh fruit, and shredded coconut for a hearty breakfast.
- Make-Ahead: Blend and freeze in ice cube trays for single-serve portions to enjoy later.
Serving Suggestions
- Pair with tropical fruit like pineapple or mango for a full island-inspired snack.
- Serve as a light dessert after a summer meal.
- Combine with a scoop of vanilla or coconut ice cream for an indulgent treat.
- Add a handful of spinach or kale to sneak in greens without overpowering the flavor.
Variations to Try
- Vegan Option: Use coconut yogurt and skip honey or use maple syrup.
- Protein Boost: Add a scoop of vanilla or unflavored protein powder.
- Green Twist: Blend in a small handful of spinach for a green smoothie version.
- Frozen Dessert: Pour into popsicle molds and freeze for Key lime pie popsicles.
