Ingredients

• Butter – Adds that rich, buttery base (use vegan or regular butter).
• Sugar – Sweetens the crust and filling naturally; you can use cane or coconut sugar.
• Gluten-Free All-Purpose Flour – Keeps the shortbread light and tender.
• Cornstarch – Helps thicken the blueberry filling for that perfect jammy texture.
• Blueberries – Fresh or frozen; they burst with flavor as they bake.
• Lemon Zest & Juice – The heart of the recipe; brings brightness and zing.
• Vanilla Extract – Adds warmth and balance.
• Salt – Just a pinch to enhance all the flavors.
• Powdered Sugar – For that sweet drizzle on top once cooled.

Directions

Step 1: Prepare the Pan

Grease an 8×8-inch pan and line it with parchment paper in a crisscross pattern for easy lifting later.

Step 2: Make the Shortbread

Beat together sugar and lemon zest until fragrant. Add the butter and vanilla, mixing until light and fluffy. Then, add flour and salt, stirring just until a crumbly dough forms.

Step 3: Create the Crust

Press two-thirds of the shortbread dough firmly into the bottom of your prepared pan. You’ll want it even and compact — this forms your sturdy, buttery base.

Step 4: Mix the Blueberry Filling

In a small bowl, toss the blueberries with sugar, lemon juice, and cornstarch until evenly coated. The mixture should look glossy and lightly thickened.

Step 5: Assemble the Layers

Spread the blueberry mixture evenly over the crust, then sprinkle the remaining shortbread dough across the top like a crumble.

Step 6: Bake

Bake until the top is lightly golden and your kitchen smells like pure happiness. The filling will bubble slightly around the edges — that’s your cue it’s done.

Step 7: Cool Completely

Let the bars cool completely in the pan. This helps them set so they slice cleanly later.

Step 8: Add the Finishing Touch

Whisk together powdered sugar and lemon juice, then drizzle it generously over the cooled bars. Slice and enjoy!

Serving Suggestions

These gluten-free dairy-free lemon blueberry bars are delightfully versatile, perfect for any time of day or occasion. Here are some delicious ways to enjoy them:

• With a scoop of dairy-free vanilla ice cream: The creamy chill of ice cream melts over the warm, crumbly bar, creating the dreamiest contrast of textures.
• Alongside a cup of iced tea or coffee: The tart lemon and sweet blueberry balance beautifully with a light, floral tea or a bold espresso.
• Topped with coconut whipped cream: A cloud of soft whipped cream adds a touch of tropical sweetness that complements the citrus so well.

Pro Tips for Success

These little insider tips will help your lemon blueberry bars come out bakery-perfect every time:

• Don’t skip the lemon zest. It’s what gives the bars their signature brightness and natural citrus aroma.
• Let the bars cool fully before slicing. This allows the blueberry layer to set and the shortbread to stay crisp.
• Line your pan generously with parchment paper. It makes lifting out the bars so much easier and keeps edges from sticking.
• Clean your knife between cuts. Wiping the blade helps you get sharp, professional-looking slices every time.
• Chill briefly before cutting. A short 10-minute chill firms the filling for ultra-clean edges.
• Use fresh blueberries when possible. Frozen ones work fine, but fresh berries give a slightly brighter flavor and texture.
• Add a drizzle of extra lemon glaze. If you love that tangy-sweet finish, double the glaze and go all in — it’s worth it!

Common Mistakes to Avoid

Even simple recipes have a few pitfalls — here’s how to avoid them:

⚠️ Overbaking: The top should be just golden; overbaking can make the crust dry. Check a few minutes early.
⚠️ Cutting too soon: Patience pays off! Wait until completely cooled so your bars hold their shape.
⚠️ Uneven crust: Press the base evenly into the pan for a consistent bite from edge to edge.
⚠️ Skipping parchment: Don’t make removal harder than it has to be — parchment is your best friend here.
⚠️ Using bottled lemon juice only: Fresh lemon juice and zest make all the difference in taste — vibrant and real.
⚠️ Forgetting to measure the filling evenly: If the blueberry layer isn’t spread evenly, some bars may bake soggy while others dry.

Storage & Reheating

Keep your lemon blueberry bars tasting as fresh as the day they were baked with these simple storage tips:

Fridge: Store in an airtight container for up to 3–4 days. The flavors actually deepen overnight!
Freezer: Freeze in layers with parchment between them for up to 2 months. Thaw overnight in the fridge for best texture.
Reheat: If you like them warm, heat gently on low in the oven or microwave for just a few seconds. Or enjoy them cold for a refreshing, chewy bite.

Frequently Asked Questions

Q1: Can I make these regular (not gluten-free or dairy-free)?
Yes! Simply swap the vegan butter for dairy butter and use regular all-purpose flour instead of gluten-free flour. They’ll turn out just as buttery and delicious.

Q2: Can I double the recipe?
Absolutely. Use a 9×13-inch pan for double the batch — perfect for parties, potlucks, or freezing extras.

Yes! Once fully cooled, wrap each bar tightly or store the whole slab in a freezer-safe container. They’ll keep for up to 3 months — just thaw before serving.

Definitely. Try raspberries for extra tang, strawberries for sweetness, or even a mix of seasonal berries. The shortbread base pairs beautifully with any fruit you love.

Q5: Can I make the filling less sweet?
You can! Reduce the sugar slightly or add a few extra drops of lemon juice to enhance the tart flavor without extra sweetness.
