What Ingredients Are in Lemon Blueberry Bars?
- Butter: Provides a rich, creamy base and helps bind the ingredients together; if you use unsalted butter, add a little bit of salt too.
- Light Brown Sugar: Adds sweetness and a slight caramel flavor to the lemon blueberry bars recipe.
- Baking Powder: Helps the bars rise and gives them a light texture.
- Egg: Acts as a binding agent to hold the bars together.
- Double Fold Vanilla Extract Recipe: Adds depth of flavor and enhances the sweetness in this blueberry lemon bar recipe.
- All-Purpose Flour: Provides structure to the lemon blueberry oat bars.
- Rolled Oats: Adds texture and a slight nuttiness.
- Sliced Almonds: Adds a crunchy texture and nutty flavor.
- Lemon Zest: Gives the blueberry lemon bars a bright, tangy flavor.
- Frozen Sweet Blueberries: Adds juicy sweetness and a burst of color.
How to Make Lemon Blueberry Bars:
- Preheat your oven and prepare your glass baking dish or metal pan with butter and lining the bottom of the pan with aluminum foil or parchment paper.
- Beat the butter in a large bowl until smooth, then mix in the brown sugar and baking powder.
- Add the egg and vanilla, mixing until combined.
- Slowly add the flour and continue mixing until well blended.
- Fold in the oats with a spoon.
- Press most of the dough into the bottom of the prepared pan, then top with the rest of the ingredients.
- Crumble the remaining dough over the top and bake until the top of the crust is golden brown and a toothpick comes out of the warm crust clean.
Pro Tip: Let bars cool over a wire rack. Once you have a cooled crust, remove the bars from the pan by lifting the tin foil out completely. Then you can cut into your preferred bar size before serving.
Are Lemon Blueberry Bars Healthy?
While Blueberry Lemon Oat Bars are a delicious treat, they are more of a dessert than a health food.
They contain butter and sugar, which add calories and fat, but the blueberries and oats do provide some nutritional benefits.
Oats are part of a heart-healthy diet and blueberries are a great source of antioxidants.
But you should enjoy these blueberry lemon oat bars in moderation as part of a balanced diet.
It’s like chocolate chip cookies, just because they have a few large eggs, that doesn’t make them healthy since the recommended amounts of nutrients is overshadowed by things you do not want to indulge in. That will throw off your nutritional daily values.
Pro Tip: If you have a hard time with a single serving of a particular food, cut this blueberry lemon bars recipe into small squares and freeze each square. Pull out whatever you want to eat that day and let it thaw at room temperature. A perfect snack in moderation!
Can You Use Fresh Blueberries in Lemon Blueberry Bars?
Absolutely you can use fresh berries instead of frozen ones to make these lemon blueberry shortbread bars.
Just be sure to rinse and dry them thoroughly before adding them to the recipe to avoid excess moisture.
How to Store Lemon Blueberry Bars:
Store Blueberry Bars in an airtight container at room temperature.
If you want to keep them longer, refrigerate them.
Can You Freeze Lemon Blueberry Bars?
Yes, you can freeze Lemon Blueberry Squares.
Wrap them individually in plastic wrap and place in a freezer-safe container.
They can be frozen for up to three months.
Pro Tip: Freeze lemon blueberry squares and use them for special on the go lunch treats. They are perfect for work and school lunches as well as fun outing snacks.
How Long Do Lemon Blueberry Bars Last?
When stored properly, Blueberry Lemon Bars will last for up to three days at room temperature, a week in the refrigerator, or up to three months in the freezer.
But the last time I made these they only lasted an afternoon before they were eaten. These always have rave reviews.
What to Serve with Lemon Blueberry Bars?
Serve these Lemon Blueberry Bars with a lot of things.
I like them warm with a dollop of whipped cream or a scoop of vanilla ice cream for an extra special treat.
They also pair well with a cup of hot tea or coffee.

I have a question about the lemon blueberry bars. Do you thaw the blueberries before using? I’ve made them twice now and have had to cook for over an hour because the batter/crust takes a while to bake because the blueberries are so wet. Seems like fresh berries may help avoid this issue too but I always have frozen berries available. Thanks

I never thaw them...I use them straight from the freezer. Every oven does cook a little differently though...perhaps there is an issue there?

For someone allergic to almonds what could be substituted? I would love to try these.

I would be uncomfortable giving anyone with allergies substitution recommendations, but why not just leave them out?
