Blueberry Blondies Ingredients
For the Blondie Base
• Unsalted Butter – Adds richness and moisture. Can use salted butter in a pinch, just reduce added salt.
• White Chocolate Chips – Provides sweetness and a creamy texture. Milk or dark chocolate can be substituted for a different flavor profile.
• Granulated Sugar – Sweetness for balance. Can replace with brown sugar for a deeper molasses flavor; reduce by 1/4 cup if using brown sugar.
• Vanilla Extract – Adds aromatic flavor. For pure flavor, use pure vanilla extract instead of imitation.
• Eggs – Binds ingredients and adds moisture. For egg-free, can substitute with flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg).
• All-Purpose Flour – Provides structure. For gluten-free, substitute with a gluten-free all-purpose blend.
• Salt – Enhances flavor. Kosher salt can be used in place of table salt.
For the Fun Addition
• Blueberries (Fresh) – Adds fruity flavor and moisture. Avoid frozen blueberries as they can alter the texture.
Indulging in these Blueberry Blondies not only satisfies your sweet cravings but also captures the essence of summer in every bite!
Step‑by‑Step Instructions for Blueberry Blondies
Step 1: Melt the Base
In a medium saucepan over low heat, melt 1/2 cup of unsalted butter until it becomes liquid. Carefully add 1 cup of white chocolate chips, stirring continuously until smooth and creamy. Once melted, remove the saucepan from heat and let the mixture cool for about 10 minutes before using to prevent melting the sugar in the next step.
Step 2: Mix Ingredients
In a large mixing bowl, combine the cooled butter-chocolate mixture with 1 cup of granulated sugar, whisking until well incorporated. Next, add 1 teaspoon of vanilla extract and 2 large eggs, mixing until fully combined. Sprinkle in 1/4 teaspoon of salt and continue to stir until the mixture is smooth and glossy, creating a delightful base for your Blueberry Blondies.
Step 3: Combine Dry Ingredients
Gently fold in 1 cup of all-purpose flour using a rubber spatula, mixing until just combined to maintain a light texture. Be careful not to overmix; this step is crucial for achieving soft, chewy blondies. Once the flour is incorporated, gently add 1 cup of fresh blueberries, ensuring they’re evenly distributed throughout the batter without crushing them.
Step 4: Bake
Preheat your oven to 350°F (175°C) and prepare an 8×8-inch baking pan by greasing it lightly with cooking spray or butter. Pour the Blueberry Blondies batter into the prepared pan, smoothing the top with a spatula. Bake in the preheated oven for 35-45 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean, signaling they’re perfectly baked.
Step 5: Cool and Serve
Once baked, remove the pan from the oven and place it on a wire rack to cool completely for at least 30 minutes. This cooling period is essential for easy slicing. Once cooled, cut the Blueberry Blondies into generous squares and serve them at room temperature or warm with a scoop of ice cream for an extra treat.

How to Store and Freeze Blueberry Blondies
Room Temperature: Store in an airtight container for up to 5 days. They’ll stay soft and chewy, perfect for snacking!
Fridge: Keep them in the refrigerator for up to 10 days. They can become slightly firmer, so allow them to come to room temperature before serving.
Freezer: For longer storage, freeze in an airtight container for up to 3 months. Wrap them individually in plastic wrap to prevent freezer burn.
Reheating: To enjoy warm, simply microwave for 15-20 seconds or warm in an oven at 350°F (175°C) for a few minutes. This revitalizes the fudgy goodness of your Blueberry Blondies!

Expert Tips for Blueberry Blondies
-
Cool the Mixture: Let the butter-chocolate mixture cool slightly before adding the sugar; this prevents the sugar from melting and ensures a perfect texture.
-
Don’t Overmix: When folding in the flour and blueberries, mix just until combined. Overmixing can lead to dense, tough blondies instead of soft and chewy ones.
-
Check for Doneness: Keep an eye on the baking time. Use a toothpick; if it comes out clean or with a few moist crumbs, your Blueberry Blondies are ready to enjoy!
-
Proper Cooling: Allow the blondies to cool completely in the pan before slicing. This step ensures clean edges and the best texture.
-
Use Fresh Blueberries: Opt for fresh blueberries for the best flavor and texture; frozen ones can make the blondies soggy and affect consistency.

Blueberry Blondies Recipe FAQs

How should I store the Blueberry Blondies?
To maintain freshness, store your Blueberry Blondies in an airtight container at room temperature for up to 5 days. If you want to extend their life, refrigerate them for up to 10 days. Just remember, they may firm up a bit in the fridge, so let them come back to room temperature before enjoying!

Yes, you can definitely freeze these delicious treats! Wrap each blondie individually in plastic wrap and place them in an airtight container. They can be stored in the freezer for up to 3 months. To enjoy, simply let them thaw in the fridge overnight or pop them in the microwave for 15-20 seconds.
What should I do if my blondies come out too dry?
If you find your Blueberry Blondies are drier than expected, it may be due to overbaking or using too much flour. To prevent this, always measure your flour properly by spooning it into the measuring cup and leveling it off. Also, keep an eye on the baking time; checking for doneness a few minutes early can help maintain that chewy texture!
Can I substitute any ingredients for dietary restrictions?
Very! If you have dietary restrictions, there are plenty of substitutions. For a gluten-free option, use a gluten-free all-purpose flour blend. You can also replace the eggs with flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg).
