Protein Blondies have totally changed my snack game. You know that late afternoon crash when you want something sweet, but then you’re like “Uh, do I really need this sugar bomb?” Yeah, I’ve been there. Honestly, most store snacks taste like cardboard or are all processed junk. What if you could treat yourself and get a little protein punch at the same time? That’s what this recipe is all about, and trust me… even my picky neighbor wanted seconds. For more easy snack ideas, check out our maple overnight oats and high protein brownies recipes too. 
Ingredients needed for protein blondies
First up, let’s be real: you want simple. Nobody wants a thirteen-step ingredient list. Here’s what you’ll need for classic protein blondies:
- 1 cup almond flour (oat flour works too if nut allergies are an issue)
- 1 scoop vanilla protein powder (any favorite brand)
- 1/4 cup nut butter (peanut or almond, whichever suits you)
- 1/4 cup honey or maple syrup
- 2 tablespoons melted coconut oil (or unsalted butter)
- 1 large egg (or a flax egg if you’re plant-based)
- 1 teaspoon vanilla extract
- 1/4 teaspoon baking powder
- Pinch of salt
- Chocolate chips (optional… but are they really?)
It’s not a scary shopping trip, right? Most of this stuff you probably have staring at you from the pantry. 
How to make protein blondies
Okay, let’s walk through this like you’re in my kitchen and we’re chatting. Grab a bowl and dump in all the wet ingredients first. Whisk them up until smooth (don’t try to cheat with a fork, it just never mixes evenly).
Now, add the dry ingredients. That lovely protein powder, almond flour, baking powder, and salt. Mix it up gently. Don’t overbeat unless you want your blondies to have the texture of an old boot (not recommended).
Fold in your chocolate chips at the last minute. Dollop the sticky goodness into a parchment-lined pan (I use an 8×8 square). Smooth it out a bit. Bake at 350F for about 18-22 minutes. If you love gooey centers… go towards 18. For firm bars, closer to 22.
Wait until they’re mostly cooled, or heck, dig in while they’re warm. Ever burned your tongue on molten chocolate? Same. Learn from my mistakes. 
Sweetener and flour substitutions
Alright, I won’t judge if you want to tinker. I do too. The cool thing about protein blondies? They’re forgiving. You can swap honey for agave, and brown rice syrup works in a pinch. Coconut sugar is tasty, just toss in a bit of extra oil or they get too dry.
Flour is a similar story. Chickpea flour (surprisingly great, adds more protein). Oat flour for a heartier vibe. Even regular all-purpose, if that’s all you have. Might need to tweak wetness, so just watch the texture. Too crumbly? Splash in extra milk or melted butter.
Boy, you can really make these your own.
| Substitute | Why Use It? | How to Swap | Extra Tips |
|---|---|---|---|
| Chickpea flour | More protein, nut-free | 1:1 for almond flour | Add 2 Tbsp milk for moisture |
| Agave syrup | Plant-based, mild flavor | 1:1 for honey/maple | Reduce oil slightly |
| Flax egg | Vegan-friendly | 1:1 for regular egg | Let it sit to thicken |
Tips for the best protein blondies
Let’s get you to five-star snack status. Seriously, a couple small tweaks and these protein blondies crush even the fancy bakery stuff.
- Spray or line your pan (there’s nothing sadder than stuck blondies).
- Don’t overmix – if you do, they get weirdly dense.
- Cool completely before slicing if you want sharp, neat squares.
- Pack in your lunchbox, or, you know, hide them from your roommate (been there).
A buddy once told me, “They’re the only blondies that don’t make me crash an hour later!” Gave me a real boost of baking confidence, not gonna lie.

Common Questions

A: Yes, absolutely. Let them cool fully, wrap individually, and freeze. Thaw in the fridge or microwave for a quick snack.
