Key Ingredients for Soft Gooey Protein Blondies
- 1 cup (240g) unsalted butter, melted
- 1 ½ cups (300g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup (120g) all-purpose flour
- ½ cup (60g) protein powder (vanilla or unflavored recommended)
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 cup (170g) white chocolate chips or chopped white chocolate
How to Make Soft Gooey Protein Blondies
Get ready for a treat that’s incredibly simple to whip up yet delivers an intensely satisfying, rich, and gooey texture. These blondies are designed for maximum flavor with minimal fuss, boasting a prep time of just 15 minutes and a bake time of 25-30 minutes. They’re the perfect solution for those moments you need a wholesome, delicious indulgence without the guilt.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan or line it with parchment paper, leaving an overhang on the sides for easy removal. This ensures your beautiful blondies won’t stick.
- Melt the Butter and Mix Wet Ingredients: In a large bowl, melt the unsalted butter. Once melted, add the granulated sugar and whisk until well combined. Beat in the two large eggs, one at a time, until the mixture is smooth and glossy. Stir in the vanilla extract.
- Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, your chosen protein powder, baking powder, and salt. This ensures an even distribution of leavening agents and protein for perfect texture and boost.
- Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to tougher blondies. A few streaks of flour are okay.
- Fold in White Chocolate Chips: Gently fold in the white chocolate chips or chopped white chocolate. Reserve a small handful to sprinkle on top before baking for extra appeal and meltiness.
- Bake to Perfection: Pour the batter into the prepared baking pan and spread it evenly. Sprinkle the reserved white chocolate chips over the top. Bake for 25-30 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crumbs attached (not wet batter).
- Cool and Cut: Let the blondies cool completely in the pan on a wire rack before cutting them into squares. This is crucial for achieving that perfect soft and gooey texture. While it’s tempting to dive in immediately, patience will be rewarded with superior texture.

Storing and Reheating Tips
Once your Soft Gooey Protein Blondies have cooled completely, proper storage is key to maintaining their delicious texture.
- Refrigeration: Store leftover blondies in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Refrigeration will firm them up slightly, but they will remain delightfully gooey.
- Freezing: For longer storage, wrap individual blondies tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months.
- Reheating: To reheat refrigerated blondies, a few seconds in the microwave (10-15 seconds per blondie) or a brief stint in a warm oven (around 300°F/150°C for 5-7 minutes) will bring back their soft, gooey perfection. Frozen blondies can be thawed at room temperature or gently reheated in the same manner once thawed.
