These turned out amazing! The recipe is so easy to follow. Instead of the glaze, I topped mine with some fresh strawberry buttercream I had on hand. They were a hit! I wouldn’t change anything about the recipe.
Just a baking tip: The center still looked uncooked (very wet/shiny) at 16 minutes so I let it bake for another few minutes. The center still looked the same, so I poked it and the stick came out clean. Mine ended up being slightly over done, but still tasted good. Next time, I’ll check it at 15 minutes.
Chahinez
So glad to hear you enjoyed this!
Maria
Excited to try these! Would love to deliver to friends. Does anyone know if the glaze hardens enough to stack? Thanks in advance 🙂
Chahinez
It’s a little bit in between. To make a glaze that would harden enough for you to stack I would recommend adding 1-3 extra TBSP powdered sugar. Start with 1 and add more if needed, you are looking for a pretty thick glaze.
Joyce Toquero
They looked so delicious and I want to make them soon but can I freeze them? If so, before glazing or after glazing.
Thank you
Chahinez
You can freeze them after the glaze to make it easier. Just make sure to allow it to set before.
Teresa
I want to make a half-sheet-pan. Would 3Xs the recipe be enough?
Teresa
4Xs worked perfectly ❤
Alex S
Phenomenal.
Chahinez
Thanks!
Rebecca
Hi can I make this recipe with an alternative to the eggs as I’m allergic? Thank you 😊
Chahinez
I have unfortunately never tried it with egg alternatives so I can’t guarantee tat you will get te same results.
Alexia
Great recipe with very easy to follow instructions! I added some cinnamon to the glaze to spice it up a bit and it was a success, my whole family loved it🦋
Chahinez
This sounds delicious Alexia!
Urich
Is there a way to make this vegan?
Chahinez
Unfortunately, I have never tried this vegan
Susan
Hopefully I’m not commenting twice. I made them today and came out awesome. Only change I made was to substitute the granulated sugar for monk fruit sugar substitute. The lemon extract helps enhance the lemony flavor without making it taste artificial. I’m definitely adding this to my personal cookbook to make again. It’s the perfect lemony treat.
Chahinez
Ohh that sounds delicious Susan. Glad to hear it turned out well!
Carly
Delicious! I used all fresh lemon juice, no extract but they were amazing
Chahinez
Glad to hear you enjoyed these Carly!
Emily
I adore this recipe, these lemon brownies are so good and just the right texture. I made them with Trader Joe’s gluten free flour and they came out a little thin and crumbly, but incredible flavor and they were gone in an instant.
Brittany
These are so easy and so good! We could not stay away. Perfectly balanced between tart and sweet. Great recipe!
Chahinez
Thank you so much!
