Kitchen Tools You’ll Need
- Mixing bowl
- Spoon or spatula
- Measuring cups
- Baking dish
Ingredients
- 1 cup nut butter (adds moisture and richness)
- 1 cup protein powder (provides structure and boosts protein content)
- 1/2 cup honey or maple syrup (brings sweetness and moisture)
- 1 teaspoon vanilla extract (enhances overall flavor)
- 1/2 cup oats (adds texture and heartiness)
- 1/4 teaspoon salt (balances sweetness)
- 1/2 teaspoon baking powder (helps with leavening)

How to Make Soft & Gooey Protein Blondies
Step 1. Begin by gathering all your ingredients into a mixing bowl. This ensures you have everything ready to go, making the process smooth. Taking a moment for this initial setup helps prevent any last-minute searching when you’re in the middle of mixing.
Step 2. In the mixing bowl, combine the nut butter and honey or maple syrup. Stir them together until well integrated and smooth. This mixture will serve as the wet base, blending flavors and ensuring moisture throughout the blondies.
Step 3. Next, add the protein powder and oats to the bowl. Gently fold them into the mixture, ensuring everything is evenly combined and no dry spots remain. The consistency should become thicker as you incorporate the ingredients, which is a good indicator that you’re on the right track.
Step 4. Incorporate the vanilla extract and salt into the batter. Stir until fully combined, which will enhance the flavor profile of your blondies. This step is crucial for achieving a well-rounded taste throughout the dessert.
Step 5. Finally, gently fold in the baking powder. This ingredient is important as it will help your blondies rise slightly. Make sure it’s evenly distributed for consistent results.
Step 6. Pour the batter into a greased baking dish, spreading it out uniformly with a spatula or the back of a spoon. This helps achieve an even bake, ensuring that every piece has the same delightful texture.
Step 7. Place the dish in the oven and bake until the blondies are lightly golden on top. A gentle visual cue for doneness is when the edges begin to pull away from the sides. Trust your instincts on texture here; they should be soft yet set.

Serving Suggestions
These protein blondies are incredibly versatile. Enjoy them as a quick breakfast on busy mornings, or pack one as a snack for the kids’ school lunches. They also make an excellent addition to family meals, offering a sweet finish that satisfies without overwhelming. If you have leftovers, simply store them in an airtight container, and you’ll have treats ready for a late-night snack or a cozy afternoon pick-me-up.
Pro Tips for Best Results
- Mix the ingredients until just combined to avoid overmixing, which can lead to a denser texture.
- Allow the blondies to cool completely before cutting for cleaner slices.
- Keep an eye on baking time; ovens can vary, so check for visual cues rather than relying solely on timing.
- Consider lightly pressing the oats into the batter for better incorporation.
- For added texture, sprinkle some extra oats on top before baking.
- Store in an airtight container to maintain freshness and texture.
Common Mistakes to Avoid
- Overmixing the batter: This can lead to a dense texture. Stir gently until just combined to maintain a softer bite.
- Not greasing the baking dish: If the dish isn’t well-greased, the blondies may stick, making them difficult to cut. A light coating ensures easy release once baked.
- Using expired baking powder: If your baking powder is old, it may not provide the needed lift, resulting in flat blondies. Check the expiration date before use.
- Baking at too high a temperature: Too much heat can lead to burnt edges while the center remains uncooked. Stick to the recommended temperature for best results.
- Not letting the blondies cool before slicing: Cutting them too soon can cause them to crumble. Patience pays off for cleaner slices.
- Using a different nut butter: Different nut butters have varying consistencies. Stick to the specified nut butter for the right texture and flavor balance.
Variations & Substitutions
For a different flavor profile, consider adding chocolate chips or chopped nuts into the batter. Adjusting the type of nut butter can also yield tasty results, such as almond or cashew butter, which might change the overall flavor subtly.
Storage & Reheating
Store the blondies at room temperature in an airtight container for a couple of days. If you’d like them to last longer, they can be kept in the refrigerator for up to a week. For longer-term storage, they can be frozen, wrapped properly in foil or a freezer-safe container. To reheat, microwave for a short time, just enough to warm through without drying them out.
