Recipe Highlights

• No oven needed: You’ll only need 6 ingredients and 10-minutes to make this tasty no-bake recipe.
• No protein powder taste: They taste like a candy bar, not a chalky protein bar.
• Nutritionally balanced: Each bar packs 10 grams of protein and 3 grams of dietary fiber to keep you full and fuelled.
• Sweet, salty, and delicious: With peanut butter, maple syrup, and just the right amount of salt, you’ll get the perfect sweet-and-salty balance in every bite.

Ingredient Notes And Substitutions

• Natural peanut butter: It’s essential that you use natural peanut butter with peanuts as the only ingredient. And make sure it’s fresh and runny – old or super thick peanut butter will make for dry bars. You can substitute almond butter or other nut and seed butters.
• Vanilla protein powder: My favorite flavored protein powder is the vanilla whey powder by Leanfit (I get this from Costco Canada), and I also love Legion. You can use any vanilla protein powder you like – but make sure it’s smooth and tasty.
• Chocolate chips: I use regular semi-sweet chocolate chips, but feel free to swap in low- or no-sugar chocolate chips to keep these bars blood sugar friendly.

Dietary swaps

• Make this dairy-free by using plant-based protein powder and dairy-free chocolate chips.
• Try peanut-free bars by swapping peanut butter for almond butter, cashew butter, or any nut or seed butter. 

Tips For Perfect Protein Bars

1. Use runny peanut butter. Natural peanut butter can dry out – and if you use dry peanut butter, you’ll have dry bars. Make sure your natural peanut butter is fresh and runny.
2. Find a tasty protein powder. The recipe doesn’t use a lot of protein powder, but you will taste it. Skip chalky protein powders and find one that’s smooth and tasty. Leanfit Vanilla Whey or Legion Whey+ in French Vanilla are my favorites.
3. Use ground flaxseeds, not whole. This is essential for a smooth bar that tastes just like Reese’s candies.
4. Don’t skip the flakey salt. This adds some nice texture and the perfect balance of sweet-and-salty flavors. I use Maldon sea salt flakes.
