High Protein Granola Bars

High Protein Granola Bars

These chewy, nutty granola bars are packed with protein from Greek yogurt, peanut butter, and a touch of whey powder, making them a satisfying grab-and-go snack. Each bar delivers over 15 grams of protein, with a pleasant texture from toasted oats and a hint of sweetness from honey and dried fruit. Perfect for post-workout recovery or a healthy afternoon pick-me-up, they stay fresh for days in the fridge.

Ingredients

Scale
  • 1 1/2 cups / 135g rolled oats (not instant)
  • 1/2 cup / 120g full-fat Greek yogurt (plain)
  • 1/4 cup / 65g creamy peanut butter
  • 3 tablespoons / 45ml honey
  • 1 scoop / 30g vanilla or unflavored whey protein powder
  • 1/4 cup / 40g dried cranberries or raisins
  • 1/4 cup / 35g unsalted almonds, roughly chopped
  • 1 large egg (lightly beaten, for binding)
  • 1/4 teaspoon kosher salt
  • 1/2 teaspoon vanilla extract

Instructions

  1. Position a rack in the center of the oven and preheat to 350°F / 177°C. Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting. This ensures the bars release cleanly without sticking.
  2. Spread the rolled oats and chopped almonds in a single layer on a rimmed baking sheet. Toast in the preheated oven for 8 to 10 minutes, stirring halfway, until the oats are lightly golden and fragrant. Toasting deepens the nutty flavor and prevents a raw oat taste in the finished bars.
  3. In a large mixing bowl, combine the Greek yogurt, peanut butter, honey, and vanilla extract. Whisk until smooth and fully incorporated. The yogurt adds moisture and protein; the peanut butter provides richness and helps bind the mixture.
  4. Add the lightly beaten egg and whisk again until the mixture is uniform. The egg acts as a binder and adds protein, helping the bars hold together without becoming crumbly.
  5. Stir in the protein powder and salt until no dry pockets remain. If the mixture seems very thick, that is correct — the protein powder will absorb moisture and help set the bars during baking.
  6. Fold in the toasted oats, almonds, and dried cranberries using a spatula. Ensure every oat and nut is evenly coated with the wet mixture; this guarantees each bar will hold together and have balanced flavor.
  7. Transfer the mixture to the prepared pan and press it firmly and evenly into the corners using a spatula or your hands slightly moistened with water. Compact, even packing is critical — loose spots create crumbly bars that fall apart.
  8. Bake for 22 to 25 minutes, until the edges are golden brown and the center feels just set but still slightly soft to the touch. Overbaking will make the bars dry and hard; underbaking leads to a gummy texture.
  9. Remove the pan from the oven and place on a wire rack. Let the bars cool completely in the pan — at least 1 hour — before lifting out. Cutting while warm causes crumbling, so patience is essential for clean slices.
  10. Once cool, lift the entire block out using the parchment overhang and transfer to a cutting board. Use a sharp chef’s knife to cut into 4 equal rectangles (or 8 smaller bars if preferred). Wipe the knife clean between cuts for neat edges.
  11. Store the bars in an airtight container in the refrigerator for up to 1 week. For longer storage, wrap individually in plastic wrap and freeze in a zip-top bag for up to 3 months — thaw in the fridge overnight before serving.

Notes

Storage: Keep in the fridge for up to 7 days. Freezing: Wrap each bar tightly in plastic wrap and place in a freezer-safe bag for up to 3 months. To thaw, transfer to the refrigerator overnight or microwave on medium power for 15 seconds. For a nut-free version, replace almonds with sunflower seeds and use sunflower seed butter instead of peanut butter. If you prefer an even higher protein bar, add an extra half scoop of whey protein and increase honey to 3.5 tablespoons to balance dryness.
