Vegan protein blondies with chocolate chips and sprinkles.

If you are looking for a quick, sweet snack loaded with melty chocolate chips and colorful sprinkles, I have got you covered with these chewy vegan blondie bars!

These blondies include vegan protein powder to up a little bit of protein content.

Ingredients like oat flour, protein powder, coconut sugar, coconut oil, and chocolate chips.

🥣 How to Make Protein Blondies

Preparing these blondies will take you about 25 minutes and require just 12 ingredients. Here is what you will need:

  • Oat flourOat flour makes the base of these bars.
  • Protein powder – Use your favorite vegan protein powder. I recommend going with a vanilla or unflavored protein powder for the best flavor. Note: I am only using 4 tablespoons of protein powder for 9 bars. I found out that using more than that yields an unpleased flavor and not the best texture.
  • Coconut oil – For richness and to give the bars a moist texture. It also works with any other vegetable oil or melted vegan butter.
  • Coconut sugar – Or brown sugar, for sweetness. If you want to lower the sugar content, feel free to replace half of the brown sugar with a sweetener.
  • Flax seeds Ground flax seeds not only prevent the bars from crumbling but also bring a bit more protein. I tried the recipe with ground chia seeds, and it worked perfectly as well!
  • Vanilla extract and cinnamon – For flavor.
  • Sprinkles – Not all sprinkles are vegan, so I highly recommend you check the ingredients. Personally, I used Sweetapolita Birthday Sprinkles here.
  • Chocolate chips – For extra sweetness. And who doesn’t like some melty chocolate chips?

Please note: These bars are definitely not as high in protein as commercial bars, but I didn’t want to sacrifice the flavor too much by adding more protein powder.

Oat flour, protein powder, coconut sugar, chocolate chips, and sprinkles in a bowl.

Start by preparing the flax egg: in a small bowl, whisk together the ground flax seeds with unsweetened almond milk. Let it sit for 5 minutes or until the mixture has thickened.

Next, combine the oat flour, protein powder, coconut sugar, baking soda, melted coconut oil, vanilla, cinnamon, and salt in a small bowl. Pour in the flax egg and mix until it forms a dough.

Preparing the batter for vegan blondies.

The batter should have the consistency of cookie dough, just a little bit softer.

Transfer the batter to a baking dish lined with parchment paper and spread it into an even layer using a spatula or a spoon.

Finally, bake for 14-15 minutes or until the top is golden brown. Let cool for a few minutes before cutting into squares!

You can enjoy these still warm or let them cool completely. I personally find the bars to taste even better the next day, as you can’t taste the protein powder anymore.

💬 FAQ

Can I omit the sprinkles?

Yes, you can omit the sprinkles. However, I would then recommend increasing the chocolate chips or coconut sugar for more sweetness.

Can I omit the protein powder?

Yes! I tried this recipe without even substituting the protein powder, and the blondies came out great.

How can I increase the protein content of these bars?

You could try to substitute some of the oat flour for extra protein powder. Be aware your bars might be a bit more crumbly and not as moist.

How long do these keep?

These protein blondies will keep for up to 4 days stored at room temperature in an airtight container. If you prefer a slightly firmer texture, store them in the refrigerator.

Saw this come through my email and made it almost immediately. Didn’t have sprinkles or chocolate chips on hands, so I omitted both. Came out really tasty… kind of like a snickerdoodle taste with the cinnamon. Of course it would be even better with the chocolate chips and sprinkles! Oh, and I used 50g date sugar and 50g cane sugar to sweeten, and sunflower oil instead of coconut oil.

Thomas– I love that you use oat flour here instead of all purpose flour. I am always trying to incorporate as much fiber into my meals, including desserts, and so many baked sweets use all purpose flour (which I try to avoid completely).

C’est magnifique! 🙂

Do you think these can be done as muffins or will they not rise the same way?
