Lemon Bars with Girl Scout Cookie Crust

If you watched the Oscars on Sunday you saw the bit where Chris Rock has Girl Scouts come out to the audience to sell cookies. It was adorable and just drove home the point that everyone loves Girl Scout cookies. Including, the man of the night, Leonardo Dicaprio. Now he may have had a lot of people talking about him finally winning an academy award after all this time or the fact that he used that moment to talk about climate change. The real conversation though was about the fact that he likes trefoils.


The academy released this picture of him the next morning and I mean just look at his face. He is so excited to go in on some trefoils and you know what, if they are good enough for Leo they are good enough for all of us. People were giving him a hard time but I actually really do like them. They are a no fuss kind of cookie and they don’t need to be all fancy to taste good. The only problem is that they aren’t cookies that I can devour an entire box of without even trying. So thanks to all the other cookies I will only eat a few of them and then they end up going bad. I decided this year to try and come up with a way to avoid that and a way to use them up so they don’t go to waste. Enter the idea for lemon bars with a trefoil crust.

I have a newfound love for lemon desserts and I’m not really sure where it came from. I wasn’t really that crazy about them before. Like I really didn’t understand what Sansa Stark was always going on about when it came to her beloved lemon cakes. Like really Sansa? I know there weren’t that many options back then but I still thought she could do better than lemon cakes. I suppose she could though if she had access to Girl Scout cookies she could have made these and really been happy.

I don’t want to be presumptuous or anything and pretend to know what makes you happy but I really do think these will brighten up your day and put a smile on your face. With the weather getting warmer these are the perfect treat for a light dessert or to take to the office or to a party. The only downside is that unless you stock up on trefoils now you can’t make them year round. You can take it as a personal challenge though to make these as many times as you can before cookie season ends though. No judgment here!

If you do try this or any other recipe, let me know! Leave a comment and don’t forget to take a picture and tag it #modernlittlevictories on Instagram! I’d love to hear what you think and what you create in your kitchen.

  3. While your crust is in the oven zest and juice your lemons. In a mixing bowl add your eggs, flour, baking powder, lemon zest and juice, and sugar. Mix until all combined and pour into dish.

    1. Haha extra isn’t a word that goes with Girl Scout cookies that’s for sure. I have to be sure to literally buy extra just for these!

  1. I love the look on Leo’s face as he anticipates eating his favourite biscuit lol. Girl Scout cookies are a uniquely American treat we Brits miss out on but I am sure I can find some good biccies to make these delicious looking lemon bars with!

    1. So do I!! He was so happy lol! Aw that is a bummer but you could probably try and make these with Walkers Shortbread and they would be just as good. I considered using those during the year when I don’t have any more Girl Scout cookies 😊

  2. I can never have enough of girl scout cookies and sometimes I have to hide it from myself to stop eating them. During such situations, I end up finding a box or two somewhere hidden and this would be a great recipe to use those up.

  3. As if a girl scout cookie couldn’t get any better! Haha! I seriously love them and wish the scouts would knock on my door more often. Then, to make them shine like the rock star they are, you turn them into a lemon bar. Bravo!!

    1. I have to go out and find the Girl Scouts myself these days! Lol! They don’t knock on doors around here anymore it seems but it’s worth finding them myself. Thank you so much Byron! 😊

  4. I love lemon desserts. Lemon bars are our family favorite especially at the beginning of Spring. These look absolutely delicious, crumbly and just perfect.

  5. I absolutely love anything lemon and these bars sound fantastic. I can see myself having some with a nice cup of tea. My healthy eating plan would be straight out the window, as l’ll be tempted to have them all.
