Chocolate Peanut Butter Protein Bars Ingredients & Substitutions

This recipe uses pantry staples with simple swaps to suit your preferences. Pay close attention to the dairy-free/vegan swaps if needed.

• Creamy peanut butter: The base of the bars, providing richness and structure; use no-stir for the best texture.
• Maple syrup: Adds natural sweetness and helps bind everything together. Honey works too, if not strictly vegan.
• Coconut oil: Helps soften the mixture and adds a smooth texture; can sub with butter if preferred.
• Vanilla extract: Enhances the overall flavor with a warm sweetness. Omit if you do not have any handy.
• Vanilla protein powder: Adds protein and structure; use your favorite dairy-free/plant-based blend if needed. I love to use Arbonne or Orgain.
• Almond flour: Keeps the bars soft and slightly chewy. Oat flour can be used as a swap.
• Coarse sea salt: Balances the sweetness and enhances the chocolate flavor.
• Dark chocolate chips: Melted for the topping; choose dairy-free/plant-based if needed. I use Pasch 85% cocoa chips.
• Milk: Helps smooth out the chocolate topping. As with the chocolate, use your favorite kind of dairy-free/plant-based milk, if needed. I personally use unsweetened almond milk.
• Optional toppings: Chopped peanuts and extra sea salt for crunch and flavor.

Chocolate Peanut Butter Protein Bars Step-by-Step Instructions

These bars come together quickly with just a few simple steps. Grab your measuring cups and spatula, and let’s get to mixing!

1. Prep: Line an 8×4-inch loaf pan with parchment paper and lightly spray with non-stick spray.
2. Melt base ingredients: In a microwave-safe bowl, heat the peanut butter, maple syrup, coconut oil, and vanilla in 30-second intervals, stirring between each, until smooth and fully combined.
3. Mix dry ingredients: Add the protein powder, almond flour, and salt, and stir until a thick dough forms.
4. Press into pan: Transfer the mixture to the prepared pan and press down firmly into an even layer.
5. Make chocolate topping: In a small bowl, melt the chocolate chips with the milk in short 30-second intervals, stirring until smooth.
6. Spread and top: Pour the melted chocolate over the base and spread evenly. Sprinkle with chopped peanuts and flaky salt if desired.
7. Chill: Refrigerate for at least 30 minutes, or until fully set.
8. Slice and serve: Cut into 10 bars or squares and enjoy.

Chocolate Peanut Butter Protein Bars Helpful Hints

A few simple tips will help you get perfect bars every time.

• Use no-stir peanut butter: Natural peanut butter can be used, but know that due to the oil content is may affect the texture. I prefer using an unsweetened, no-stir peanut butter for the best consistency.
• Adjust consistency if needed: If the dough feels too dry, add a tiny splash of milk; too soft, add a bit more almond flour.
• Press firmly: Compacting the base well helps the bars hold together when sliced.
• Don’t overheat chocolate: Melt in short intervals to avoid burning or seizing.
• Chill completely before slicing: This ensures clean cuts and firm bars.
