Ingredients You’ll Need

Before we get to baking, gather the following ingredients. Don’t worry, I’ve included easy substitutions if you’re out of something or want to tweak the recipe! 

For the Blondie Bars 

• 1/2 cup unsalted butter, melted (Swap for coconut oil for a lighter version) 
• 3/4 cup coconut sugar (Use brown sugar if needed) 
• 2 large eggs 
• 1 tablespoon lemon zest (Trust me, this is where some major flavor magic happens!) 
• 2 tablespoons lemon juice 
• 1 teaspoon vanilla extract 
• 1 cup all-purpose flour (Substitute with gluten-free flour for a GF version) 
• 1/2 teaspoon baking powder 
• 1/4 teaspoon salt 

For the Blueberry Whirl 

• 1/2 cup fresh or frozen blueberries (Fresh ones will pop with flavor!) 
• 1 tablespoon honey or maple syrup 
• 1 teaspoon cornstarch 

Optional Glaze 

• 1/4 cup powdered sugar 
• 1 tablespoon lemon juice 

Now that you’ve got everything, it’s time for the fun part—baking! 

Step-by-Step Instructions

Step 1: Prep and Preheat 

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. This makes cleanup a breeze and ensures your blondies don’t stick. 

Step 2: Make Your Blueberry Whirl 

• Heat the blueberries, honey, and cornstarch in a small saucepan over medium heat. 
• Stir until the mixture thickens and becomes jammy (about 3-5 minutes). Set it aside to cool. 

Pro Tip: If you want extra smooth swirls, give the mixture a quick blitz in a blender. 

Step 3: Mix the Wet Ingredients 

• Melt the butter (or coconut oil) and combine it with coconut sugar in a large bowl. 
• Add the eggs, lemon zest, lemon juice, and vanilla extract. Whisk until smooth! 

Step 4: Combine Dry Ingredients 

• In another bowl, mix the flour, baking powder, and salt. Slowly fold the dry mixture into the wet bowl until just combined. Be careful not to overmix! 

Step 5: Assemble 

• Pour the batter into your prepared pan. 
• Dollop the blueberry swirl over the top and use a knife or toothpick to create beautiful swirls by gently dragging the mixture through the batter. 

Step 6: Bake Away! 

Bake your bars for 25-30 minutes or until the edges are golden and a toothpick inserted in the center comes out clean. 

Reminder: Your whole kitchen will smell incredible by now! 

Step 7: Optional Glaze 

While the blondies cool, mix powdered sugar and lemon juice to create a delightful glaze. Drizzle over the cooled bars for an extra zesty touch.

Tips and Tricks for Perfect Blondies

1. Don’t Skip the Zest – The secret to bold lemon flavor? The zest! It holds all those aromatic oils and makes your bars pop. 
2. Fresh vs. Frozen Blueberries – Fresh berries tend to hold their shape, while frozen ones may bleed slightly. Either works and adds charm! 
3. Storage – Keep your blondies in an airtight container at room temperature for up to 3 days—or refrigerate for up to a week. You can also freeze them for a month! 
4. Gluten-Free Tip – For best results with gluten-free flour, use one with a blend of rice flour, potato starch, and xanthan gum.
