Blueberry Blondies….because moist, golden blondies are always a good idea, especially with fresh lemon juice, zest, and a hint of cardamom. Studded with a generous cup of fresh, in season blueberries, these bars are finished with the easiest sweet-tart lemon icing. They’re gooey, buttery, so pretty and the perfect sweet treat for summer days!
BLONDIES
When I think of gooey, buttery desserts, brownies such as my rich tahini brownies or s’mores brownies automatically come to mind. That said, I do love a good blondie! I don’t know if I’d go as far as this bold article from delish.com which argues why blondies are better than brownies (!) but I do agree that blondies are pretty great!
My favorite point the author makes is that blondies are almost always homemade which is something I never thought about. It’s so true though, you almost never see boxed blondie mixes!
I recently made my flavorful coconut butterscotch blondies and realized they were the only blondie recipe on my site. I decided it was time for a new blondie recipe and was excited to try them with blueberries!

BAKING WITH BLUEBERRIES
There’s something so warm and comforting about baking with blueberries. They’re juicy, delicious and just lovely to bite into! Whenever I bake with blueberries, I almost always include lemon. Both their flavors and colors are so bright, cheery, and summery that I always want to pair them together. My Lemon Blueberry Baked Donuts are so tender and flavorful and these Lemon Blueberry Muffins are as close to bakery style as I’ve come with any muffin so far!
Blondies are typically on the rich side and desserts with blueberries are usually lighter and fresher which lands these blueberry blondies somewhere in between. They’re super moist and buttery yet full of juicy, fresh flavor! The blueberries almost give these blondies a bit of a a coffee cake taste to them. Does that mean it’s okay to have blondies for breakfast?!
In addition to vanilla, these blondies are flavored with one of my favorite spices: cardamom. You can’t quite pinpoint cardamom’s flavor, but it adds to the warmth and can’t put it down flavor of these bars!

HOW TO MAKE BLUEBERRY LEMON BLONDIES?
The fact that these bars are super easy to throw together makes them perfect for summertime! They’re an easy, sweet treat that lets you keep things simple and leaves you tons of time to be outdoors.
To make them, start by combining melted butter and brown sugar. Whisk in an egg and some vanilla. Add the dry ingredients and blueberries and mix just til combined then pour it into your pan.
That’s it! Two bowls, well you could even skip the bowl for the dry ingredients and add everything directly to the wet mixture. Also, no mixer. It’s that easy. The batter seriously comes together in minutes, does not take much effort and leaves you with a minimal mess to clean up.


EASY LEMON ICING
I can attest to the fact that these blondies are delicious plain! That said, I loved the added sweetness of this easy lemon icing. It also brings out all the lemon flavor inside the bars!
To make the icing, you just stir together some powdered sugar, lemon juice and zest until smooth. No need to sift the powdered sugar since it’ll pretty much dissolve/melt with the lemon juice.

Use a spoon to just drizzle the icing over the cooled bars. If you prefer your icing on the thicker side and find that the spoon doesn’t drizzle the icing the way you’d like, try a sandwich bag. Just scoop or pour the icing into a little bag and snip a little corner. Use the bag to pipe/drizzle the icing over the bars.
This tart, sweet icing is the same icing I used for both my Roasted Strawberry Crumb Bars and Sour Cream Lemon Cookies! They’re so delicious and so are these donuts!



Warm, tender, sweet and moist, these blueberry blondies are proof that fruit goes well with blondies. Make them when you’re craving something fruity, gooey and delicious!

Hi, I just wanted to ask a question about your blueberry blondies. When you talked about the icing, you said it helped to bring out the flavor of the lemon inside the bars, but I dont see there being any lemon added to the blondie batter. What did you mean by that? I think putting some lemon in the batter would be a yummy thing. How would you go about doing that? Thanks for your time.

Hi Jennessa thanks so much for noticing that! You are right, the lemon was missing from the recipe. Sorry for that inconvenience. The blondie batter should have 2 teaspoons of lemon zest in it. I just updated it so it’s now there in the recipe. Also, you’re right-the lemon in the batter is definitely yummy 🙂 Thanks again! -Natalie
Simply delicious and a must try.
