For the Blondie Batter
• Unsalted Butter – Provides richness and moisture; use salted butter if necessary, but reduce added salt.
• White Chocolate Chips – Adds sweetness and a creamy flavor profile; substitute with vanilla chips if desired.
• Granulated Sugar – Sweetens the blondies; brown sugar can be used for a deeper flavor.
• Vanilla Extract – Enhances flavor complexity; opt for pure vanilla for the best taste.
• Eggs – Binds the ingredients and adds moisture; ensure they are at room temperature for better emulsification.
• All-Purpose Flour – Provides structure and stability; for a gluten-free version, use a gluten-free flour blend.
• Salt – Balances sweetness and enhances flavors.

Step‑by‑Step Instructions for Blueberry Blondies

Step 1: Melt the Butter and White Chocolate
In a saucepan over low heat, melt 1 cup of unsalted butter, stirring gently until fully liquid. Remove from heat and immediately add 1 cup of white chocolate chips, letting them sit for about 5 minutes. Then, whisk the mixture until smooth and glossy. Allow it to cool at room temperature for around 30 minutes, thickening as it does.

Step 2: Mix the Blondie Batter
In a large mixing bowl, combine the cooled butter and white chocolate mixture with 1 cup of granulated sugar. Whisk until well blended, then add 1 teaspoon of pure vanilla extract. Incorporate 2 large eggs, one at a time, whisking until fully combined to create a rich and glossy batter.

Step 3: Combine Dry Ingredients
Gently sift in 1 cup of all-purpose flour and 1/2 teaspoon of salt into the wet ingredients, folding in with a rubber spatula until just combined. Be careful not to overmix, as this will affect the final texture. Delicately fold in 1 cup of fresh blueberries, ensuring they are evenly distributed throughout the batter for delightful bursts in your Blueberry Blondies.

Step 4: Bake
Preheat your oven to 350°F (175°C) while preparing an 8×8-inch baking dish by greasing it or lining it with parchment paper. Pour the blondie batter into the prepared dish, spreading it evenly. Bake in the preheated oven for 35-45 minutes, until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs.

Step 5: Cool and Serve
Once baked, remove the Blueberry Blondies from the oven and allow them to cool in the baking dish for about 10 minutes. Then, transfer to a wire rack to cool completely to room temperature. Slice into 12-16 generous pieces, ready to be enjoyed at your next gathering or cozy afternoon treat!

Make Ahead Options

These Easy One-Bowl Blueberry Blondies are a fantastic choice for meal prep! You can prepare the blondie batter up to 24 hours in advance. Simply mix all the wet and dry ingredients, then store the batter in an airtight container in the fridge to maintain freshness. When you’re ready to bake, let the batter sit at room temperature for about 15-20 minutes before pouring it into the baking dish and baking as directed. Alternatively, you can also bake the blondies in advance and store them in an airtight container for up to 5 days at room temperature or up to 10 days in the fridge, ensuring they stay just as delicious. This way, you can have a scrumptious treat ready for unexpected guests or a quick indulgence during busy weeknights!

Storage Tips for Blueberry Blondies

Room Temperature: Store your Blueberry Blondies in an airtight container at room temperature for up to 5 days to maintain their chewy texture and freshness.

Fridge: If you’d like to extend their shelf life, refrigerate the blondies for up to 10 days. Ensure they are wrapped tightly to prevent them from drying out.

Freezer: For longer-term storage, freeze the blondies for up to 3 months. Wrap them in plastic wrap and then seal in a freezer bag to keep them fresh.

Reheating: To enjoy them warm, simply reheat individual pieces in the microwave for about 10-15 seconds, restoring that comforting fudgy texture.

Expert Tips for Blueberry Blondies

• Cool Ingredients: Allow the melted butter and chocolate to cool for at least 30 minutes to avoid melting the sugar granules, ensuring a light, chewy texture.

• Mix Gently: When folding in the flour and blueberries, mix just until combined. Overmixing can lead to dense blondies that lack that delightful chewiness.

• Perfect Blueberries: Use fresh blueberries for optimal texture and flavor; frozen berries may make your blondies soggy and heavy.

• Watch the Bake Time: Keep an eye on your blondies while baking, as ovens vary. Remove them when golden brown and a toothpick comes out with just a few moist crumbs.

• Storage Tips: Store your Blueberry Blondies in an airtight container at room temperature for up to 5 days for the best taste and texture.

Blueberry Blondies Recipe FAQs

How do I choose the best blueberries for my blondies?
Absolutely! When selecting blueberries, look for plump, firm berries with a deep blue color. Avoid any that have dark spots or appear shriveled. Fresh blueberries are key for the most vibrant flavor and texture in your Blueberry Blondies.

How should I store leftover blondies?
For sure! Store your Blueberry Blondies in an airtight container at room temperature for up to 5 days. If you need them to last longer, pop them in the fridge, where they can stay fresh for up to 10 days. Just make sure to wrap them tightly to prevent drying out.

Can I freeze my Blueberry Blondies?
Yes, you can! To freeze your Blueberry Blondies, wrap them in plastic wrap and then place them in a freezer-safe bag to keep them fresh. They will hold up well in the freezer for up to 3 months. When you’re ready to enjoy, just thaw them in the fridge overnight or warm a piece in the microwave for that freshly-baked taste!

Why are my blondies too dense?
Very good question! Overmixing the batter is often the culprit when blondies turn out dense. Be gentle when folding in the flour and blueberries; mix just until combined. Also, ensure that your butter and chocolate mixture cools long enough before adding the sugar, as this prevents the sugar from melting too much.

Can my pets eat blueberries from these blondies?
While fresh blueberries are safe for dogs in moderation, the other ingredients in your Blueberry Blondies, such as sugar and butter, are not suitable for pets. It’s best to keep these treats for your human friends!

Can I substitute ingredients for dietary restrictions?
Absolutely! For a gluten-free version, swap out all-purpose flour for a gluten-free flour blend. If you’re looking to lower the sugar content, consider using a sugar substitute in a similar ratio. Just keep in mind that different alternatives may affect texture and flavor, so a bit of experimentation might be needed!
