Recipe: Lemon squares

Soooo ages and ages ago I made lemon squares (mentioned in this blog).
Ages and ages ago I said I would post the recipe because they were delicious and I never got around to it.... Also I typed it into a word document, forgot about it and then when I finally found it, I deleted it, thinking that I'd already posted it.
Sometimes I spectacularly resemble an airhead.
So I've decided that now, since the weather is warm and lemon is super refreshing, I'll just have to post up the recipe.  Yes, it requires opening your oven, but not for very long so it's worth it.  As soon as your lemon squares are done, let them cool, take them out of the pan and cool in the fridge.
Totally and absolutely worth it.
And the recipe really is quite simple with minimal ingredients.  Even the crust is easy to make (although

I suppose you could easily buy one as well (think graham cracker lol)...
I have to give credit to Joy the Baker and Luscious Lemon for inspiration. I modified and combined their two recipes for the perfect lemon square.
I made these with lemons from my student's garden and then fed them to my classes. They were quite successful! Successful enough to make me want to make more. Which I finally did yesterday (sometimes it takes me time to get to my projects) and I played around with my base recipes again. I made Strawberry Lemonade Bars.  I'll try to post up the recipe tomorrow (since I'm typing it here, maybe I'll actually do it in a timely fashion!).

Cover your oven proof dish with aluminum foil for easy cleanup!

Ingredients
crust:

• 1/2 cup (1 stick butter) room temperature
• 1/2 cup granulated sugar
• 1 cup all purpose flour 
• pinch of salt

filling:

• 3 eggs
• 1 cup sugar
• 1/3 cup freshly squeezed lemon juice
• 1 tbs freshly zested lemon zest 
• 3 tbs all purpose flour

Line an oven proof pan with aluminum foil or parchment paper for easier cleanup.  Preheat your oven to 350°F. 

So many levels of utterly delicious

If you have an electric mixer, I would use it to cream the butter and sugar.  I don't have an electric mixer, sooo I was forced to do it by hand. It just takes a little more time and patience but it's totally doable.  Add the salt and flour and mix well.  When it's a cohesive mixture and not too sticky (add a little more flour if you need to) press it into your pan.  

Bake for 15 minutes, until lightly golden on the edges.
While the crust is baking whisk together the eggs, sugar, lemon juice, lemon zest and flour.  Whisk until cohesive.
Pour the filling over the crust and bake for 20-25 minutes or until the lemon filling is set and firm.  Keep a close eye on your lemon bars and rotate to make sure they color evenly.
Let cool completely and then cut into squares.  I used a round form, so the edges weren't square... which is fine, because I ate them before anyone could see!
Put in the refrigerator and serve chilled.

See, absolutely simple and deliciously amazing!
