• Granulated Sugar – Sweetens the batter; feel free to use brown sugar for a deeper flavor profile.
• Vanilla Extract – Enhances the overall flavor; pure vanilla extract yields the best results.
• Eggs – Binds the ingredients and contributes to the chewy texture; flax eggs can be used for vegan alternatives.
• All-Purpose Flour – Provides structure; substitute with gluten-free flour for a gluten-free treat.
• Salt – Balances the sweetness; omit if using salted butter.

Step‑by‑Step Instructions for Blueberry Blondies
Step 1: Prepare the Butter and Chocolate
Begin by melting ½ cup of unsalted butter in a saucepan over low heat, stirring gently until fully melted. Remove the pan from the heat and pour the warm butter over 1 cup of white chocolate chips in a mixing bowl. Let the mixture sit for 5 minutes, then whisk until smooth and glossy. Allow it to cool for about 30 minutes, ensuring it’s at a warm but not hot temperature for the next step.
Step 2: Mix the Wet Ingredients
In a separate large mixing bowl, combine the cooled butter and white chocolate mixture with 1 cup of granulated sugar. Whisk until fully integrated and smooth. Next, add 1 teaspoon of pure vanilla extract and two large eggs, whisking vigorously until the mixture is combined and slightly frothy. This will ensure your blueberry blondies have a lovely chewy texture.
Step 3: Incorporate the Dry Ingredients
Gently fold in 1 cup of all-purpose flour and ½ teaspoon of salt into the wet mixture using a spatula. Use a light hand to prevent overmixing, which can affect the blondies’ texture. Once the flour has just incorporated, add in 1 cup of fresh blueberries, folding them into the batter carefully to avoid bursting the berries while ensuring an even distribution throughout the mix.
Step 4: Bake the Blondies
Preheat your oven to 350°F (175°C) and line an 8×8 inch baking dish with parchment paper, allowing an overhang for easy removal. Pour the batter into the prepared dish, spreading it evenly to the corners. Bake in the preheated oven for 35-45 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
Step 5: Cool and Slice
Once baked, remove the blueberry blondies from the oven and let them cool in the pan for at least 20 minutes. This step is essential for achieving the perfect fudgy texture. After cooling, lift the blondies out using the parchment overhang and transfer them to a cutting board. Slice into squares and savor the delightful freshness that bursts from every bite!

Make Ahead Options
These fudgy blueberry blondies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the batter up to 24 hours in advance by mixing all the ingredients and transferring it to a lined baking dish. Simply cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, allow the batter to come to room temperature for about 30 minutes before placing it in the oven. This approach ensures that your blueberry blondies come out just as delicious as if you made them fresh! Additionally, feel free to store the baked blondies in an airtight container at room temperature for up to 5 days or refrigerate them for up to 10 days, ensuring they remain chewy and moist.
