Ingredients

Scale
  • 2 cups (180g) rolled oats (old-fashioned)
  • 1 cup (250g) natural peanut butter (creamy or chunky)
  • 1/4 cup (85g) honey (or maple syrup for vegan option)
  • 1 teaspoon vanilla extract
  • 2 large eggs (room temperature)
  • 1/2 cup (50g) whey or plant-based protein powder (unflavored or vanilla)
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/4 cup (60ml) milk of choice (dairy or dairy-free like almond or oat milk)
  • 1/2 cup (75g) chopped nuts or chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, combine rolled oats, protein powder, baking powder, and salt. Stir well to evenly distribute.
  3. In a separate bowl, whisk together peanut butter, honey, eggs, vanilla extract, and milk until smooth and creamy.
  4. Pour the wet mixture into the dry ingredients. Fold gently with a spatula until just combined. If using, stir in chopped nuts or chocolate chips.
  5. Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
  6. Bake for 25-30 minutes, starting to check at 25 minutes by inserting a toothpick in the center; it should come out mostly clean with a few moist crumbs.
  7. Remove from oven and let cool in the pan for about 15 minutes. Use the parchment paper overhang to lift the bars onto a wire rack to cool completely before slicing into 12 bars.

Notes

Use room temperature eggs and peanut butter for easier mixing. Do not overmix the batter to keep bars tender. Start checking baking time at 25 minutes to avoid drying out. Let bars cool completely before slicing to prevent crumbling. Protein powder is optional but recommended for texture and nutrition. For vegan version, substitute eggs with flax eggs and honey with maple syrup.
