Lemon-Blueberry Crumb Bars Ingredients
Here’s what you’ll need to create these delightful bars. Don’t worry, the list is short and sweet!
- ‘1 stick butter melted’
- ‘1 box lemon flavored cake mix’
- ‘2 eggs’
- ‘2 8 oz. packages Cream Cheese softened’
- ‘1/2 cup sugar’
- ‘1 Tbsp. zest’
- ‘3 Tbsp. lemon juice’
- ‘2-1/2 cups blueberries’

Step-by-Step Instructions: How To Make Lemon-Blueberry Crumb Bars
Now for the fun part! Here’s how to bring these Lemon-Blueberry Crumb Bars to life. Don’t be intimidated – it’s easier than you think!
- Get Started: Preheat your oven to 350ºF (175ºC). Line a 13×9-inch pan with foil, making sure the ends of the foil extend over the sides. This will make it easy to lift the bars out later.
- Make the Crust: In a large bowl, mix the dry lemon cake mix with the melted butter and 1 egg. Use with mixer until blended. The mixture will be crumbly, and that’s exactly what you want.
- Press the Crust: Press 2/3 of the dough mixture onto the bottom of the prepared pan. Use your fingers or the back of a spoon to create an even layer.
- Make the Filling: In another bowl, beat the cream cheese and sugar with mixer until blended, until smooth and creamy. This step is crucial for a luscious filling. Add the remaining egg, lemon zest, and lemon juice; mix well.
- Assemble the Bars: Pour the cream cheese mixture over the crust. Sprinkle the blueberries evenly over the cream cheese layer. Then, sprinkle small pieces of the remaining third of the dough over the cream cheese/berry layer, pressing down lightly.
- Bake: Bake for 50 minutes to 1 hour, or until a toothpick inserted in the center comes out clean. Keep an eye on the bars towards the end of baking time. If the top starts to brown too quickly, cover the bars with foil to prevent overbrowning.
- Cool and Chill: Let the bars cool completely in the pan. Then, refrigerate for several hours (or overnight) for easy cutting. This step is essential for achieving clean, neat slices.
- Slice and Serve: When ready to cut, use the foil handles to lift the bars from the pan. Cut into squares and serve chilled.
And there you have it! Beautiful, delicious Lemon-Blueberry Crumb Bars, ready to impress your friends, family, or just yourself. These bars are a delightful treat, and I hope you enjoy making and eating them as much as I do.
Pro Tips for Perfect Lemon-Blueberry Crumb Bars
Want to take your Lemon-Blueberry Crumb Bars from good to absolutely amazing? Here are a few of my top tips:
- Softened Cream Cheese is Key: Make sure your cream cheese is fully softened before mixing. This will ensure a smooth, lump-free filling.
- Zest with Love: Don’t skip the lemon zest! It adds a ton of flavor and aroma to the bars. Use a microplane grater for the finest zest.
- Gentle with the Berries: When adding the blueberries, try not to squish them too much. You want them to stay intact for that perfect burst of flavor in every bite.
- Patience is a Virtue: Resist the urge to cut into the bars before they’re fully chilled. This will prevent them from crumbling and ensure clean slices.
- Use Quality Ingredients: The better the ingredients, the better the bars! Opt for fresh, juicy blueberries and high-quality cream cheese for the best results.
Common Mistakes to Avoid
Even the most experienced bakers make mistakes sometimes. Here are a few common pitfalls to watch out for when making Lemon-Blueberry Crumb Bars:
- Overbaking: Overbaking can result in dry, crumbly bars. Keep a close eye on them and remove them from the oven as soon as a toothpick comes out clean.
- Using Cold Cream Cheese: Cold cream cheese will be difficult to mix and can result in a lumpy filling. Make sure it’s fully softened before using.
- Not Pressing the Crust Firmly Enough: If the crust isn’t pressed firmly enough, it can crumble easily. Use your fingers or the back of a spoon to create a solid base.
- Skipping the Chilling Time: Chilling the bars is essential for easy cutting and a firm texture. Don’t skip this step!
- Using Too Much Flour: If you add too much flour to the crumb topping, it can become dry and dense. Use a light hand when mixing the topping.
Lemon-Blueberry Crumb Bars Variations
Want to mix things up? Here are a few fun variations to try with these Lemon-Blueberry Crumb Bars:
- Raspberry-Lemon Crumb Bars: Swap the blueberries for fresh raspberries for a different flavor profile.
- Strawberry-Lemon Crumb Bars: Use diced strawberries instead of blueberries for a summery twist.
- Lemon Poppy Seed Crumb Bars: Add 1-2 tablespoons of poppy seeds to the cream cheese filling for a subtle nutty flavor.
- Gluten-Free Lemon-Blueberry Crumb Bars: Use a gluten-free lemon cake mix and gluten-free flour for the crumb topping to make these bars gluten-free.
- Add a Glaze: Drizzle a simple lemon glaze over the cooled bars for an extra touch of sweetness and flavor. Make the glaze by whisking together powdered sugar and lemon juice until smooth.
These bars are a blank canvas for your creativity! Feel free to experiment with different fruits, extracts, or toppings to create your own signature version.

Frequently Asked Questions (FAQ)
Here are some common questions about making Lemon-Blueberry Crumb Bars:
- Can I use frozen blueberries? Yes, you can use frozen blueberries, but make sure to thaw them completely and drain off any excess liquid before adding them to the bars.
- Can I make these bars ahead of time? Absolutely! These bars are a great make-ahead dessert. You can bake them a day or two in advance and store them in the refrigerator until ready to serve.
- Can I use a different type of cake mix? While I recommend using a lemon cake mix for the best flavor, you can experiment with other flavors like vanilla or yellow cake mix.
- My bars are too crumbly. What did I do wrong? If your bars are too crumbly, it could be due to not pressing the crust firmly enough or overbaking them. Make sure to press the crust firmly and keep a close eye on the bars while they’re baking.
