Ingredients

Scale
  • 2 cups (about 200g) vanilla or birthday cake flavored whey or plant-based protein powder
  • 1 ½ cups (135g) rolled oats
  • 1 cup (250g) creamy, unsweetened almond butter
  • ½ cup (120ml) honey or maple syrup
  • ½ cup (120ml) unsweetened almond milk
  • 2 teaspoons vanilla extract
  • ¼ cup (20g) sprinkles (optional)
  • 1 teaspoon baking powder
  • ¼ teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 inch (20×20 cm) pan with parchment paper, leaving some overhang for easy lifting.
  2. In a large bowl, combine protein powder, rolled oats, baking powder, and salt. Stir until evenly blended.
  3. In a separate bowl, whisk together almond butter, honey or maple syrup, almond milk, and vanilla extract until smooth and creamy.
  4. Pour wet ingredients into the dry mixture. Stir gently until a thick batter forms. If too dry, add almond milk one tablespoon at a time.
  5. Fold in sprinkles gently to distribute color without melting them.
  6. Transfer batter to the lined pan. Press evenly and firmly into all corners using a spatula or lightly dampened hands.
  7. Bake for 15 to 18 minutes. Check when edges turn golden and a toothpick inserted comes out mostly clean with a few moist crumbs.
  8. Cool bars completely in the pan on a wire rack for at least 30 minutes. Use parchment overhang to lift out and cut into 10-12 bars.
  9. Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.

Notes

[‘Do not skip lining the pan with parchment paper to avoid difficult cleanup.’, ‘Do not overmix to prevent dense and tough bars.’, ‘Press batter firmly into the pan to help bars hold shape and prevent crumbling.’, ‘Start checking baking at 15 minutes to avoid drying out bars.’, ‘Sprinkles can be swapped with mini chocolate chips; reduce baking powder slightly if doing so.’, ‘For vegan version, replace honey with maple syrup and use plant-based protein powder.’, ‘For nut-free version, substitute almond butter with sunflower seed butter or tahini.’, ‘Bars can be stored in the fridge up to one week or frozen up to three months.’, ‘Reheat bars in microwave for 10-15 seconds for a soft, freshly baked feel.’, ‘Flavors deepen overnight, so making bars a day ahead enhances taste.’]
