Ingredients You’ll Need
Got your apron on? Here’s the simple list of ingredients to transform your kitchen into a lemon-blueberry wonderland:
- 1/2 cup butter or coconut oil (for a vegan option)
- 1 cup all-purpose flour or gluten-free flour
- 1/2 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup blueberries (fresh or frozen)
- 2 tablespoons lemon juice
- 1 tablespoon lemon zest
- 1/4 cup powdered sugar (for dusting, optional)
How to Make (Step-by-Step)
STEP 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking dish. We’ll be working some magic here, so get ready!
STEP 2: Cream the Butter and Sugar
In a mixing bowl, cream together the butter (or coconut oil) and the granulated sugar until it’s all smooth and dreamy. Seriously, the aroma is heavenly.
STEP 3: Mix in Dry Ingredients
Gradually add the flour, baking powder, and salt. Mix until you get a crumbly texture that holds together. This crumbly goodness is what makes these bars so irresistible!
STEP 4: Press Half Into the Baking Dish
Now, press half of that crumb mixture into the bottom of your prepared dish to form a delightful crust.
STEP 5: Prepare the Blueberry Mixture
In another bowl, combine the blueberries, lemon juice, and lemon zest. Spread that vibrant blueberry mixture evenly over the crust. Your senses are in for a treat!
STEP 6: Crumble the Remaining Mixture
Now, crumble the remaining crumb mixture on top of those beautiful blueberries. It’s time for the finishing touch!
STEP 7: Bake!
Pop your pan in the oven and bake for 25-30 minutes, or until the top is golden brown and your kitchen smells like a bakery. Heaven, right?
STEP 8: Cool and Serve
Let it cool for a bit before you cut it into bars. Don’t forget to dust with powdered sugar before serving—if you’re feeling fancy!
Pro Tips for the Best Results
- Use Fresh Ingredients: They really enhance the flavor. Fresh lemons? Yes, please!
- Adjust Sweetness: If you like things a little sweeter, add an extra tablespoon of sugar to the crumb mixture.
- Chill Time: For cleaner cuts, let the bars cool completely before slicing them.
- Baking Time: Keep an eye on them, as oven temperatures can vary. You want that golden perfection!
Fun Variations & Topping Ideas
Variations
- Add Nuts: Toss in some chopped walnuts or almonds for a crunchy twist.
- Fruits Galore: Swap blueberries for raspberries, strawberries, or even peaches. Get creative!
- Herbal Twist: Add a hint of fresh mint or basil to the blueberry mix for an unexpected flavor combo.
Toppings

- Chocolate Chips: Because who doesn’t love chocolate? Seriously, you can thank me later.
- Whipped Cream: Treat yourself to a dollop of whipped cream for that extra indulgence.
Storing and Reheating
Storing
Keep your Lemon Blueberry Crumb Bars in an airtight container in the fridge for up to 5 days. They won’t last too long, but if they do, you’ll be a synth of taste!

If you like them warm (and who doesn’t?!), pop them in the microwave for about 10-15 seconds. Just enough to bring that melt-in-your-mouth goodness back!
