Ingredients

Frozen Ripe Banana: Adds natural sweetness and creaminess as the smoothie’s base, while keeping the texture thick and smooth.
Lime or Key Lime Zest: Infuses aromatic citrus oils for an extra punch of bright, tangy flavor.
Fresh Lime or Key Lime Juice: Provides fresh acidity and tartness that balances the sweetness and enhances the pie-like taste.
Vanilla or Coconut Greek Yogurt: Brings creaminess and a subtle vanilla note; coconut yogurt is perfect if you want to keep it dairy free.
Light Coconut Milk: Adds tropical richness with a silky, smooth texture without overpowering the drink.
Fresh Spinach: A mild green that adds nutrients and vibrant color without altering the fruity taste.
Vanilla Extract: Enhances all the flavors and adds warmth and depth to the smoothie.
Maple Syrup or Honey (Optional): Additional natural sweetener if you prefer a sweeter smoothie; adjust to taste.
Graham Cracker Crumbs: Used for rimming the glass to evoke the classic key lime pie crust texture and flavor.
Whipped Cream: For topping, adds indulgent creaminess and visual appeal.
Shredded Toasted Coconut: Provides a crunchy topping with a nutty coconut flavor to finish the smoothie beautifully.

Instructions

Prepare the Glass Rim: Start by crushing graham crackers onto a small plate. Wet the rim of your serving glass with a lime wedge, then gently dip and roll the rim into the graham cracker crumbs until evenly coated. This mimics the classic pie crust and adds delightful texture and flavor with every sip.
Combine Smoothie Ingredients: In a high-powered blender, add the frozen banana slices, lime zest, fresh lime juice, vanilla or coconut yogurt, light coconut milk, fresh spinach, and vanilla extract. Blending these ingredients together creates a creamy, nutrient-rich smoothie. Use coconut yogurt and milk to keep the smoothie dairy free if desired.
Blend Until Smooth: Blend all ingredients on high until smooth and creamy, adding extra milk if needed to reach your preferred consistency. Taste your smoothie and add 1-2 teaspoons of maple syrup or honey if additional sweetness is desired, though vanilla yogurt usually provides enough natural sweetness.
Serve with Toppings: Pour the smoothie into your prepared glass. Top generously with whipped cream and sprinkle shredded toasted coconut on top for added texture and flavor. Garnish with an extra lime wedge if desired for a fresh finishing touch.
