What Are Pistachio Chocolate Chip Protein Bars?

These no-bake bars are made with rolled oats, protein powder, nut butter, and naturally sweet ingredients like honey or maple syrup. Crunchy pistachios and melty mini chocolate chips add irresistible flavor and texture, while chia seeds or flaxseed give an extra boost of fiber and healthy fats.

Pressed into a pan and chilled instead of baked, they’re quick to make, easy to store, and way more fun (and nourishing) than anything store-bought.

What Do They Taste Like?

These bars are soft, chewy, and slightly crunchy from the chopped pistachios and chia seeds. The nut butter and honey give them a creamy richness, while the vanilla (or chocolate) protein powder brings that classic “snack bar” vibe.

How to Make Pistachio Chocolate Chip Protein Bars

Step 1: Mix Dry Ingredients

In a large bowl, stir together the rolled oats, chopped pistachios, protein powder, chia or flaxseed, and mini chocolate chips.

Step 2: Combine Wet Ingredients

In a separate bowl, mix the almond butter, honey or maple syrup, and vanilla extract until smooth and well blended.

Step 3: Mix & Adjust

Pour the wet ingredients into the dry and stir until a thick, slightly sticky dough forms.
If the mixture feels too dry, add 1 tablespoon of water at a time until it’s firm but pliable and holds together.

Step 4: Press & Chill

Line an 8×8-inch baking pan with parchment paper. Press the mixture firmly into the pan, smoothing the top with a spatula.
Refrigerate for at least 1 hour to set.

Step 5: Slice & Store

Once firm, lift from the pan and slice into 10–12 bars or squares. Store and snack away!

Tips for Success

• Use drippy nut butter for easy mixing and smooth texture
