You’ll also love how customizable this recipe is. You can switch up the protein powder flavor, add crunchy toppings, or make them completely dairy-free with a few simple swaps. They store beautifully in the fridge or freezer, making them perfect for meal prep.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 3/4 cup no-stir creamy peanut butter
• 1/4 cup maple syrup
• 1 tablespoon melted coconut oil
• 1 teaspoon vanilla extract
• 1/2 cup vanilla protein powder
• 1/3 cup almond flour
• 1/2 teaspoon coarse sea salt
• 1/3 cup dark chocolate chips
• 3 tablespoons milk
• Optional chopped peanuts for topping
• Optional coarse sea salt for garnish

The peanut butter forms the creamy base of the bars and helps bind everything together. Maple syrup adds natural sweetness while keeping the texture soft and chewy. Almond flour creates structure without making the bars dry, and the protein powder boosts the nutritional value while adding flavor.

Dark chocolate chips melted with milk create a silky topping that hardens beautifully once chilled.

Directions

1. Line an 8×4-inch loaf pan with parchment paper and lightly grease it with non-stick spray.
2. In a microwave-safe bowl, combine the peanut butter, maple syrup, coconut oil, and vanilla extract. Heat in 30-second intervals, stirring after each interval until the mixture is smooth.
3. Add the vanilla protein powder, almond flour, and sea salt. Stir until a thick dough-like consistency forms.
4. Transfer the mixture into the prepared pan and press it firmly into an even layer.
5. In a separate microwave-safe bowl, combine the dark chocolate chips and milk. Heat in short intervals, stirring often, until melted and smooth.
6. Pour the melted chocolate over the peanut butter base and spread evenly with a spatula.
7. Sprinkle chopped peanuts and coarse sea salt over the top if desired.
8. Refrigerate the bars for at least 30 minutes or until fully set.
9. Slice into 10 bars and serve chilled.

Servings and timing

This recipe makes approximately 10 protein bars.

Variations

For a crunchier texture, use crunchy peanut butter instead of creamy peanut butter.

Chocolate lovers can mix a tablespoon of cocoa powder directly into the base for an extra rich flavor.

Swap peanut butter for almond butter or cashew butter if you prefer a different nutty taste.

Add shredded coconut, mini chocolate chips, or chopped nuts for more texture and flavor.

If you enjoy sweeter bars, drizzle extra melted chocolate over the top before chilling.

You can also use chocolate protein powder instead of vanilla protein powder for a double chocolate version.

Storage/Reheating

Store the protein bars in an airtight container in the refrigerator for up to 2 weeks. Keeping them chilled helps maintain their firm texture and fresh flavor.

For longer storage, freeze the bars for up to 3 months. Place parchment paper between layers to prevent sticking.

To enjoy frozen bars, let them thaw in the refrigerator overnight or sit at room temperature for about 10 minutes before eating.

These bars are best served cold, so reheating is not necessary.
