Ingredients You’ll Need

• ½ cup unsalted butter
• ½ cup white chocolate chips
• 1 cup granulated sugar
• ½ tsp vanilla extract
• 2 large eggs
• 1 cup all-purpose flour
• ½ tsp salt
• ½ cup fresh blueberries (washed and dried)

Ingredient Notes and Variations

Feel free to swap the white chocolate chips for a chopped white chocolate bar for a richer texture. If using salted butter, omit the added salt. For a healthier twist, try replacing half the flour with almond flour or whole wheat flour. You could also add a pinch of lemon zest to enhance the blueberry flavor. While fresh blueberries work best, be sure not to substitute with frozen ones, as they release too much moisture.

Step-by-Step Preparation: How to Make Blueberry Blondies

Step 1:

Preheat your oven to 350°F and line an 8×8-inch baking pan with parchment paper.

Step 2:

In a saucepan, melt the butter over medium heat. Place white chocolate chips in a heatproof bowl and pour melted butter over them. Let sit for 5 minutes, then whisk until smooth. Allow mixture to cool for about 10–15 minutes.

Step 3:

Whisk in the granulated sugar followed by the vanilla extract and eggs. Mix until fully incorporated.

Step 4:

Add in the flour and salt, folding gently with a spatula until just combined.

Step 5:

Fold in the blueberries carefully so they don’t burst.

Step 6:

Spread the batter evenly into the prepared pan. Smooth the top with a spatula.

Step 7:

Bake for 30–35 minutes or until the top is golden and a toothpick inserted comes out clean or with just a few crumbs.

Step 8:

Allow the blondies to cool completely in the pan before slicing into 12–16 squares.

Pro Tips for the Best Blueberry Blondies

Let the butter-white chocolate mixture cool before adding sugar and eggs to avoid a greasy texture. Always dry your blueberries thoroughly to prevent extra moisture in the batter. Don’t overbake—these are meant to be fudgy, not cakey. Lastly, line your baking pan with parchment for easy removal and clean edges.

Common Mistakes to Avoid

Using frozen blueberries is a no-go—they release water and make the bars soggy. Overmixing the batter can lead to tough blondies, so fold ingredients gently. Also, adding too many mix-ins (extra blueberries or chocolate) can weigh the batter down and ruin the texture.

Serving Suggestions

Serve these blondies slightly warm with a scoop of vanilla ice cream or a dollop of whipped cream. For a brunch twist, serve alongside Lavender Mojito Mocktail or Lemon Basil Cookies for a citrusy pairing. They also go great with a cup of tea or iced coffee.

Creative Presentation Ideas

Cut into triangles for a playful shape or use cookie cutters for themed parties. Dust with powdered sugar or drizzle with melted white chocolate for an extra elegant touch. You can also layer them in a dessert jar with whipped cream and extra berries for a parfait-style treat.

Flavor Variations and Add-Ins

Try adding chopped nuts like almonds or macadamia for a crunchy element. A swirl of cream cheese or lemon curd can add tang. You can even fold in shredded coconut or a hint of cinnamon for a tropical or spiced profile. For a twist, use raspberries or blackberries instead.

How to Store and Reheat

Store in an airtight container at room temperature for up to 5 days. Refrigerate for up to 10 days, or freeze for up to 3 months. To enjoy warm, microwave individual blondies for 10–15 seconds. For best texture, let them come to room temp before serving.

Make-Ahead Tips

These blondies can be made a day ahead and stored at room temperature. You can also mix the batter and refrigerate it (covered) for up to 24 hours before baking. Just let it sit at room temperature for 15 minutes before spreading into the pan.
