Key Lime Yogurt Bark

This Key Lime Pie Yogurt Bark has become my summer salvation—a protein-packed frozen treat that satisfies sweet cravings while keeping things light and nutritious. The tangy lime flavor paired with the creamy yogurt base creates all the flavors of key lime pie without the heavy feeling afterward.

I first created this recipe during a particularly brutal heatwave when my family was craving something cool but I wanted to avoid the sugar crash from store-bought popsicles. Now it's requested weekly during summer months, and I always keep a batch in the freezer.

Ingredients

• Greek yogurt: serves as the creamy, protein-rich base that freezes beautifully and provides that satisfying mouthfeel
• Key lime juice: delivers authentic tangy flavor that makes this bark special use fresh if possible for the brightest taste
• Powdered sweetener or honey: balances the tartness without overwhelming it
• Vanilla extract: adds depth and warmth to the cold treat
• Lime zest: intensifies the citrus flavor and adds beautiful specks of color
• Crushed graham crackers: provide that authentic key lime pie crust experience and essential textural contrast
• Toasted coconut: contributes subtle sweetness and a wonderful crunch factor
• Vanilla protein powder: boosts nutritional value while enhancing the creamy texture

Step-by-Step Instructions

Prepare the yogurt base:

Combine Greek yogurt, key lime juice, protein powder, lime zest, sweetener and vanilla in a bowl, whisking until completely smooth. Take your time here to ensure no lumps remain for the creamiest possible texture.

Create the bark layer:

Line a baking sheet with parchment and spread the yogurt mixture into an even layer about 1/4-inch thick. Use an offset spatula to create a perfectly smooth surface that will freeze evenly throughout.

Add toppings:

Sprinkle the crushed graham crackers, toasted coconut and additional lime zest evenly across the surface. Press gently to adhere without pushing too deeply into the yogurt layer.

Freeze until solid:

Place the baking sheet in the freezer for at least 2-3 hours until completely set. The bark should feel firm to the touch with no soft spots remaining.

Break and serve:

Once frozen, lift the parchment from the baking sheet and break the bark into irregular pieces. Enjoy immediately for maximum texture and flavor.

Pin it

The lime zest is truly the magical ingredient in this recipe. When I first developed this bark, I skipped the zest thinking the juice would be enough, but adding those fragrant oils from the peel transformed it from good to extraordinary. My daughter now helps me zest the limes and calls it "lime confetti" as we sprinkle it across the top.

Texture Variations

The fat content of your yogurt dramatically affects the final texture of your bark. Using full-fat Greek yogurt results in a creamier, less icy consistency that melts more smoothly on the tongue. However, non-fat Greek yogurt creates a lighter, more refreshing bark with slightly more pronounced ice crystals. I personally prefer full-fat for dessert-like occasions and non-fat for post-workout snacking.

Make It Dairy-Free

This recipe adapts beautifully to dietary restrictions. Substitute the Greek yogurt with coconut yogurt for a dairy-free version that complements the lime flavor profile perfectly. The natural sweetness of coconut yogurt might allow you to reduce the added sweetener. Using plant-based protein powder ensures the recipe remains entirely dairy-free while maintaining its protein boost.

Serving Suggestions

For an elevated dessert experience, serve your yogurt bark with additional fresh fruit like blueberries or diced mango on the side. The contrast between the frozen bark and room-temperature fruit creates a delightful temperature play. For special occasions, place bark pieces in small dessert cups with a dollop of coconut whipped cream and a tiny wedge of fresh lime for garnish.

Seasonal Adaptations

While key lime provides the classic flavor, this recipe framework welcomes seasonal variations. In fall, try substituting pumpkin puree and cinnamon for the lime juice and zest. Winter calls for cranberry and orange, while spring shines with lemon and fresh berries. The basic preparation remains the same, allowing you to enjoy this healthy treat year-round with seasonal ingredients.
