These lemon brownies are full of fresh lemon flavor. They have white chocolate, so they are a brownie! It is also topped with a lemon glaze. These brownies have that fudgy texture and decadent flavor that marks a great brownie, but with a white chocolate and lemon twist!

These lemon brownies take take the best traits of a brownie and fresh fruit flavors of lemons and brings them together. Tart lemon and sweet white chocolate make a refreshing and exciting taste that is better than any other lemon desserts I have tried.

Tips for making the brownies
Here are my tips, so yours turns out like this recipe!
- Tip 1: When you are baking the brownies, you need to be careful when you stir in the rest of the ingredients after the eggs are beaten. If they are added in too fast, the eggs’ air will deflate and you won’t get as much of a rise from the brownies.
- Tip 2: Make sure to spray the pan with baking non-stick spray, so the brownies don’t stick to the pan. It is also a good idea to place parchment paper on the bottom of the tray as well. Make sure your parchment paper comes far enough up the sides that you can use it as a handle to lift the brownie to make removing it from the tray easier.
- Tip 3: When beating the eggs and sugar together, you should be able to rub the batter between your fingers and not feel any sugar granules. This helps give it is crinkle top.

If I leave out the lemon (zest and juice), will that affect the texture? I searched for a blondie recipe on your website and this was the closest I could find. Or, if I missed it, could you direct me to it? I love your recipes!
Excellent! I’ll be making these again.
I made these a few weeks ago and loved them! I plan on making them again but I wanted to put the batter in a mini cupcake tray so they’re bite sized and can be easily served! How long do you recommend I cook them for? When I cook box brownies I will cook them for ~20 minutes. Should I just cook until a toothpick comes out clean or golden brown on top? Please let me know!
Hello! How can I make these brownies gluten and dairy free??
So I made these a second time and left them in the oven until the edges were browning and it was baked through and it still fully deflated after I pulled it out of the oven. 🙁 I beat the eggs for a full 5 minutes, my oven was at 325, I used a 9×9 metal pan. The sinking happened twice so I’m not sure what I’m doing wrong. I see the note about them sinking because they’re underbaked but I wonder if anyone else has experienced this multiple times and has tips to avoid it?
If doubled do I use 9×13 pan?
Yes!
If you double the recipe, how long should you bake it?
I would bake these for 50 mins to 1 hour. Check at 50 mins!
I baked fir about an hour! Omg these are amazing! So fudge-like and perfect lemon flavor. Even if I do not add the glaze it amazing but the glaze gives it an extra flavor. Everyone loves them!
These are DELICIOUS! They were a hit with all of my friends! So pretty and a great consistency. I did 1/4 cup LESS sugar than the recipe called for and they were still perfectly sweet.
really amazing and refreshing recipe which wasn’t too difficult to make. personally it was VERY sweet but that’s probably just personal preference so not worth docking any stars. well done
Hello,
This recipe sounds amazing! Which rack level does this need to be baked on?
My go to fudgiest brownie recipe has it bake on the very top rack to prevent it from getting to dry. Is this recipe anything like or does it bake on the middle rack?k
thank you!
I always bake on the middle rack.
These are FANTASTIC. I pulled mine out too early and they sank badly, but the taste and texture were still 10/10. These are quite different from a traditional lemon bar – the white chocolate really does add a great subtle flavor and texture. I added extra lemon zest to the glaze for more of a pop. Can’t wait to make these again!
These are so fragrant and perfect texture. A recipe I’ll come back to time & again.
Lemon brownies are amazing!
I had to use an 8×12-inch glass pan as I did not have any square pans. Brownies are delicious. I toyed with not using the glaze but that totally finishes off the brownies. Don’t skip it.
Perfect recipe.
I don’t like chocolate, so can I just leave it out?
Yes you can.
