  • High in Protein: Using protein powder and nut butters, these blondies support muscle recovery and keep you full longer.
  • Simple Ingredients: No complicated or hard-to-find items — just wholesome staples like oats, honey, and almond butter.
  • Gluten-Free Option: Easily adaptable with gluten-free oats to accommodate dietary needs.
  • Versatile: Add nuts, chocolate chips, or dried fruit for your preferred flavor combo.
  • Quick to Make: Minimal prep and baking time make this an ideal recipe for busy days.

Ingredients

  • 1 cup rolled oats (gluten-free if necessary)
  • 1/2 cup vanilla protein powder (whey or plant-based)
  • 1/4 cup almond butter (or peanut butter)
  • 1/3 cup honey or maple syrup for a vegan option
  • 1 large egg (or flax egg for vegan)
  • 1 tsp vanilla extract
  • 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1/4 cup dark chocolate chips (optional but highly recommended)
  • 1/4 cup chopped walnuts or pecans (optional)

Equipment

  • Mixing bowl
  • Measuring cups and spoons
  • Whisk or spoon for mixing
  • 8×8 inch baking pan
  • Parchment paper or non-stick spray
  • Oven
  • Cooling rack

Instructions

  1. Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper or lightly grease it to prevent sticking.
  2. Mix the dry ingredients: In a large bowl, combine the rolled oats, protein powder, baking powder, and salt. Stir until evenly distributed.
  3. Combine wet ingredients: In a separate bowl, whisk together the almond butter, honey, egg, and vanilla extract until smooth and creamy.
  4. Combine wet and dry: Pour the wet mixture into the dry ingredients. Stir well until a thick batter forms. If it’s too dry, add a tablespoon of water or almond milk.
  5. Add mix-ins: Fold in the chocolate chips and nuts gently, distributing them evenly throughout the batter.
  6. Transfer to the pan: Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
  7. Bake: Place in the oven and bake for 15-18 minutes, or until the edges are lightly golden and a toothpick inserted comes out mostly clean with a few moist crumbs.
  8. Cool: Remove from the oven and allow the blondies to cool completely in the pan on a cooling rack before slicing.
  9. Slice and serve: Cut into 12 squares and enjoy your protein-packed treat!

Tips & Variations

“For an extra fudgy texture, slightly underbake the blondies and let them set as they cool. To keep them vegan, swap the egg for a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) and use maple syrup instead of honey.”

  • Add dried fruit: Toss in raisins, dried cranberries, or chopped dates for natural sweetness and texture.
  • Switch up the nut butter: Try cashew, sunflower seed, or tahini for unique flavors.
  • Use flavored protein powder: Chocolate or peanut butter protein powder can add extra depth.
  • Make bite-sized bars: Use a mini muffin tin or silicone molds for portable snacks.
  • Include spices: A pinch of cinnamon or nutmeg pairs beautifully with the vanilla base.
