Protein White Chocolate Raspberry Blondies - Soft, Chewy, and Packed With Flavor
Ingredients
- 1 cup (120 g) oat flour (store-bought or blended rolled oats)
- 1/2 cup (60 g) vanilla whey or plant-based protein powder (see notes below)
- 1/2 teaspoon baking powder
- 1/4 teaspoon fine sea salt
- 1/3 cup (65 g) coconut sugar or light brown sugar
- 1/4 cup (60 ml) maple syrup
- 1/4 cup (60 g) Greek yogurt (or dairy-free yogurt)
- 1/3 cup (80 ml) melted coconut oil or unsalted butter, slightly cooled
- 1 teaspoon pure vanilla extract
- 1 large egg (or 1 flax egg: 1 tbsp ground flax + 3 tbsp water, rested 5 minutes)
- 1/2 cup (90 g) white chocolate chips or chopped white chocolate
- 3/4 cup (100 g) fresh raspberries (or frozen, kept frozen until mixing)
- Optional: 1–2 tablespoons milk if batter is too thick
Instructions
- Prep the pan. Preheat the oven to 350°F (175°C). Line an 8x8-inch (20x20 cm) pan with parchment paper, leaving some overhang for easy lifting. Lightly grease the sides.
- Mix the dry ingredients. In a medium bowl, whisk together oat flour, protein powder, baking powder, and salt until no lumps remain. This keeps the crumb even.
- Combine the wet ingredients. In a large bowl, whisk coconut sugar, maple syrup, Greek yogurt, melted coconut oil or butter, vanilla, and the egg until smooth and glossy.
- Bring it together. Add the dry ingredients to the wet. Stir with a spatula until just combined. If the batter seems stiff or crumbly, add 1–2 tablespoons of milk to loosen it. The texture should be thick but spreadable.
- Fold in the good stuff. Gently fold in the white chocolate and raspberries. If using frozen raspberries, add them straight from the freezer to reduce bleeding and overmixing.
- Spread and smooth. Transfer the batter to the prepared pan. Use a spatula to spread it to the corners and smooth the top. For extra flair, press a few extra white chocolate chips or raspberries on top.
- Bake. Bake for 18–24 minutes, depending on your oven and protein powder. The edges should look set and lightly golden, and the center should still be a bit soft. A toothpick should come out with a few moist crumbs, not wet batter.
- Cool and slice. Let the blondies cool in the pan for at least 20–30 minutes. Lift out using the parchment, then cut into 12 squares. Cooling helps them firm up to that perfect fudgy texture.
What Makes This Special
These blondies balance buttery vanilla flavor with tart, juicy raspberries. White chocolate melts into pockets of sweetness while the protein powder helps them feel more satisfying.
The texture is soft, fudgy, and slightly gooey—exactly what you want from a blondie. You can also tweak the sweetness and richness based on your protein powder and chocolate choice. Plus, they’re simple enough for a weeknight bake but nice enough to share.
Ingredients
- 1 cup (120 g) oat flour (store-bought or blended rolled oats)
- 1/2 cup (60 g) vanilla whey or plant-based protein powder (see notes below)
- 1/2 teaspoon baking powder
- 1/4 teaspoon fine sea salt
- 1/3 cup (65 g) coconut sugar or light brown sugar
- 1/4 cup (60 ml) maple syrup

Protein Powder Note: Different powders absorb liquid differently.
Whey creates a softer, chewier blondie. Plant-based powders may need a splash of milk to prevent dryness.
Step-by-Step Instructions
- Prep the pan. Preheat the oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) pan with parchment paper, leaving some overhang for easy lifting.

How to Store
- Room temperature: Keep in an airtight container for 1–2 days.
- Refrigerator: Store up to 5 days.
They get denser and fudgier when chilled.
- Freezer: Wrap individually and freeze for up to 2 months. Thaw at room temp or warm in the microwave for 10–15 seconds.
Tip: Add a small square of parchment between layers to prevent sticking.
Why This is Good for You
These blondies are a treat with benefits. The protein powder and Greek yogurt add extra protein, which helps keep you full longer.
Oat flour brings fiber and a gentle, nutty flavor. Raspberries add vitamin C and natural tartness to balance sweetness. You still get dessert vibes, just with better macros than a typical blondie.
Pitfalls to Watch Out For
- Overbaking: Protein treats can dry out fast.
Pull them when the edges set and the center is slightly soft.
- Too much protein powder: Extra scoops can make the texture chalky. Stick to the listed amount.
- Overmixing raspberries: This can streak the batter and make it soggy. Fold gently at the end.
- Hot butter or oil: If your fat is too warm, it can scramble the egg or melt the chocolate.
Let it cool slightly first.
- Wrong pan size: A larger pan makes thin, dry blondies. Aim for 8×8 inches for best results.
Variations You Can Try
- Lemon zest boost: Add 1–2 teaspoons of fresh lemon zest to the batter for a bright twist that pairs well with raspberries.
- Almond touch: Swap vanilla for 1/2 teaspoon almond extract and add sliced almonds on top.
- Lower sugar: Replace coconut sugar with a granulated sweetener of choice and keep maple syrup as is for moisture.
- Chocolate swap: Use dark or milk chocolate chips instead of white for a less sweet profile.
- Gluten-free: Use certified gluten-free oats to make your own oat flour, or a trusted GF oat flour brand.
- Dairy-free: Use coconut oil, dairy-free yogurt, and a plant-based protein powder.
- Nut butter swirl: Dollop 2–3 tablespoons of cashew or almond butter on top and swirl before baking.
FAQ
Can I use almond flour instead of oat flour?
You can, but the texture will be softer and more fragile. If using almond flour, start with 1 cup and add a tablespoon or two more if the batter feels loose.
Expect a richer, slightly denser blondie.
What protein powder works best?
Whey or a whey-casein blend usually gives the chewiest, most brownie-like crumb. Plant-based powders (like pea or rice) can work well too but may need an extra splash of milk and a minute less in the oven to stay moist.
Can I use frozen raspberries?
Yes. Use them straight from the freezer and fold in gently to minimize bleeding.
You may need to add 1–2 extra minutes to the bake time.
How do I keep them from getting dry?
Measure the protein powder accurately, don’t overbake, and don’t skip the yogurt or maple syrup. If the batter looks stiff, add a tablespoon or two of milk. Pull them from the oven when the center still looks slightly soft.
Do they taste “healthy”?
No.
They taste like soft, vanilla-scented blondies with pops of sweet white chocolate and tart raspberry. The protein simply adds structure and a more satisfying bite.
Can I double the recipe?
Yes. Bake in a 9×13-inch pan for 22–28 minutes.
Keep an eye on the edges and test the center with a toothpick for moist crumbs.
What’s the best way to cut clean squares?
Let the blondies cool completely, then use a sharp knife wiped clean between cuts. Chilling them for 30 minutes first makes slicing even tidier.
In Conclusion
Protein White Chocolate Raspberry Blondies are a simple, feel-good dessert that doesn’t skimp on flavor. They’re sweet, tangy, and satisfyingly chewy, with an easy batter you can whip up anytime.
Keep a batch in the fridge or freezer for quick snacks, lunchbox treats, or a post-workout bite. Once you try them, you’ll want to keep the ingredients on hand for your next craving.
