Looking for a snack that’s both tasty and good for you? These key lime protein balls have become my go-to treat when I need a quick energy boost. I started making them last summer when I wanted something that would satisfy my sweet tooth without derailing my healthy eating habits.
What I love most about these little bites is how simple they are to put together. No baking required, and you can make a batch in about 15 minutes. I usually whip them up on Sunday afternoons while meal prepping for the week. They’re perfect for grabbing between meetings or tossing in my gym bag.
The best part? They taste just like key lime pie, but without all the guilt. If you’re a fan of tart, sweet flavors and need something that’ll keep you going through the afternoon slump, these protein balls are exactly what you’re looking for.

What Kind of Dates Should I Use?
Medjool dates are your best bet for these protein balls since they’re naturally softer and more caramel-like in texture than other varieties. They blend more easily and help bind the ingredients together better than their firmer cousins like Deglet Noor dates. If your dates feel a bit dry or stiff, just soak them in warm water for about 10 minutes before using – this will make them easier to blend and ensure your protein balls hold together well. When shopping, look for dates that are shiny, plump, and don’t have any sugar crystals on the surface (though if they do, they’re still totally fine to use).
Options for Substitutions
These protein balls are pretty flexible and can be customized based on what you have in your pantry:
- Dates: If you’re out of dates, you can use dried figs or prunes instead. Just make sure they’re soft and sticky to help bind the mixture together.
- Cashews: Any nuts will work here! Try almonds, macadamia nuts, or even pecans. Just keep in mind that each nut will add its own unique flavor to the final product.
- Almond butter: Feel free to swap in cashew butter, peanut butter, or sunflower seed butter (for a nut-free option). The texture might be slightly different, but they’ll still hold together well.
- Protein powder: Any protein powder works – whey, pea, hemp, or brown rice protein. Just note that different proteins absorb moisture differently, so you might need to adjust the wet ingredients slightly.
- White chocolate chips: Dark chocolate chips work great too, or you can skip the chocolate coating entirely and roll the balls in extra shredded coconut or crushed nuts.
- Shredded coconut: If you’re not a coconut fan, you can replace it with ground flax seeds or extra protein powder. The texture will be different but still tasty!
Watch Out for These Mistakes While Making
The biggest challenge when making protein balls is getting the right consistency – if your mixture is too dry, the balls won’t hold together, so start by processing the dates until they form a sticky paste before adding other ingredients. Another common mistake is rushing the chilling process – these protein balls need at least 30 minutes in the refrigerator to firm up properly, otherwise they’ll be too soft to handle and coat with white chocolate. When melting the white chocolate, be careful not to overheat it or it will become grainy and unusable – instead, melt it slowly in 30-second intervals in the microwave, stirring between each interval, or use a double boiler method. For the best lime flavor, make sure to zest your limes before juicing them, and avoid the bitter white pith when zesting.
What to Serve With Key Lime Protein Balls?
These protein balls make a perfect grab-and-go snack, but there are lots of tasty ways to enjoy them as part of a bigger spread! Try serving them alongside your morning coffee or tea for a quick breakfast that’ll keep you going. They’re also great paired with a smoothie – I especially like combining them with a tropical green smoothie made with mango and spinach to complement the lime flavor. For a post-workout snack, serve these protein balls with some fresh fruit like strawberries or banana slices, or add them to a snack board with nuts and dark chocolate for a healthy-ish dessert spread.
Storage Instructions
Keep Fresh: These key lime protein balls stay perfectly snackable in an airtight container in the fridge for up to 2 weeks. I like to place a piece of parchment paper between layers to keep them from sticking together. They’re great to grab whenever you need a quick energy boost!
Freeze: Want to make a bigger batch? These little treats freeze really well! Just pop them in a freezer-safe container and they’ll stay good for up to 3 months. I often make a double batch and freeze half for later – it’s such a time-saver.
Thaw: When you’re ready to enjoy your frozen protein balls, just transfer them to the fridge the night before. They’ll be perfect by morning! If you’re in a hurry, letting them sit at room temperature for about 30 minutes works too.

Ingredients
For the energy balls:
- juice of 1 lime (about 2 tbsp)
- 1/3 cup unsweetened shredded coconut
- zest of 2 limes (about 1 tbsp, for maximum citrus flavor)
- 1/2 tsp sea salt
- 1/4 cup white chocolate chips
- 3/4 cup cashews
- 1/2 cup almond butter (I prefer Barney Butter for this recipe)
- 2 scoops protein powder (vanilla or unflavored work great)
- 8 pitted dates (Medjool dates work best for their softness)
For the drizzle:
- 1/4 cup white chocolate chips
- 1 tsp coconut oil (melts smoothly with the chocolate)
Step 1: Process Dates and Cashews
Begin by placing the dates in a food processor and pulse until they achieve a caramel-like consistency.
Next, add the cashews and process until the mixture takes on a sand-like texture blended with the dates.
Step 2: Incorporate Almond Butter and Coconut
Add the almond butter and coconut to the date-cashew mixture.
Pulse again until all ingredients are evenly mixed, ensuring a uniform consistency.
Step 3: Add Flavor and Protein
To the mixture, add the protein powder, half of the lime zest, all of the lime juice, and a pinch of sea salt.
Process until the ingredients become smooth, ensuring all flavors are well incorporated.
Then, add half of the white chocolate chips and pulse 2-3 times to lightly mix them into the blend.
Step 4: Form the Energy Balls
Using a large cookie scoop, portion out approximately 12 balls from the mixture.
It may seem a bit crumbly; use your hands to press them firmly together, shaping the balls securely.
Step 5: Prepare White Chocolate Drizzle
Melt the remaining 1/4 cup of white chocolate chips with about 1 teaspoon of olive oil or coconut oil in a microwave for about 30 seconds or until fully melted.
Drizzle this melted white chocolate over the tops of the energy balls.
Step 6: Garnish and Store
Finish the energy balls by sprinkling the remaining lime zest on top of the white chocolate drizzle.
To keep them fresh, store the energy balls in the refrigerator, ready to enjoy whenever you need a nutritious snack!
