FREQUENTLY ASKED QUESTIONS:
Just like chocolate brownies, these lemon ones are dense and moist. They aren’t cakey. If you’re wanting cake-y bars, you’ll need to add a an additional leavening agent like baking powder to get that rise and airiness in them.
While I imagine you could ditch the glaze, I find that it really takes these bars up a notch. The lemon citrus flavor in it really makes them pop too. You could change the lemon extract to a different extract if desired or swap it out for something thicker if desired.
You can add whatever you like with these bars. Personally, I think adding some poppy seeds would be great. They are light, easy and would still let the lemon flavor shine through. You could also try some mini baking chips if desired or white chocolate chips.
Absolutely! If you love Lemon Brownie bars as much as we do, then you’re going to want to make a double batch 🙂
I suggest using a 9×13-inch baking pan and bake them that way. You’ll need to increase the baking time though.
Yes! I have a recipe for Homemade Lemon Brownies you can use instead.
Keep any leftovers in an airtight container at room temperature for up to three days.
Yes, these flavored brownies can be frozen to keep longer. I like to flash freeze them before transferring them to a freezer safe container and freezing for up to 3 months.
Let them thaw in the fridge overnight before eating again. If you flash freeze them, you can just grab one or two, or a handful to enjoy later without having to thaw the whole leftover batch.

INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)
- lemon cake mix – I know that they keep going down in sizes for cake mixes. This recipe will work with the 13 ounce boxes all the way up to the 18 ounce boxes (if you can still find those anymore.) This won’t work with the Jiffy Cake mixes unless you grab two boxes of those.
- eggs – if you have time allow the eggs to come to room temperature. This will allow them to mix into the batter much easier.
- unsalted butter – if all you have is salted butter then you can use that. There is so little salt in salted butter and the amount we’re using here that it won’t make much of a difference.
- lemon extract – you could also use fresh lemon juice or lemon zest if you can’t find lemon extract.
- powdered sugar
- milk – if you really want to take it up a notch, try using heavy cream!

HOW TO MAKE LEMON BROWNIES
Preheat your oven to 350 degrees F. and prepare an 8×8-inch pan by spraying generously with non-stick spray and line the bottom with parchment paper. Set aside. In a large mixing bowl. Mix the cake mix, melted butter, and lemon extract. Add in eggs. Mix until just combined, the mixture will be thick! Press the mixture into the prepared baking dish.

Bake 18-20 minutes or until a toothpick inserted in the center of the brownies comes out clean. Remove from the oven and allow to cool completely on a wire rack. To make the glaze, combine the powdered sugar, lemon extract, and milk in a medium bowl and whisk until combined. Pour over the cooled brownies and smooth evenly.

Cut into 9 pieces and serve!
