2 ingredient...Lemon squares

Happy 4th of July! Wow, it is July already and the heat and humidity have been unbearable. It is stifling outside. What a day to put the oven on and bake.

Two Ingredient Lemon Squares.....
Yes, this cake only uses  2 ingredients.
1 box angel food cake mix( I used Betty Crocker)
2 cans lemon pie filling..I used two - 21 oz cans of Lucky Leaf pie filling ( total of 42 oz) , because I couldn't find Comstock lemon pie filling.
Mix dry cake mix and the 2 cans of lemon pie filling together in a large bowl.
I just mixed it by hand with a rubber spatula. The batter will be heavy but fluffy
Pour mix into a greased 9 x 13″ baking pan.
Bake at 350 degrees for 25 minutes or until top is starting to brown.
NOTE...Because I used a 3 quart Pyrex baking dish mine took longer than 25 minutes to bake.  When baking in glass you need to lower the baking temperature by 25 degrees. I did turn up the oven to 350 degrees after 35 minutes, because the center of the pan of mix when tested with a toothpick for doneness still came out wet. I lost track of time, and maybe let them brown a little too much baking at  35o degrees.
Cool cake in the pan/dish on a wire rack. Then sprinkle with powered sugar when cake is cool. The cake has a melt in your mouth spongy texture.
I found this recipe on several sites on the internet. So, I thought I would give it a try.
I took step by step photos while making these squares.

done mixing and you can see that the combined ingredients are quite puffy
in a greased dish and ready to put into the oven
baking in the oven the cake rose high  over the sides of the baking dish
top of cake just after taking out of the oven
cooling on rack
after cooling for awhile the cake's height dropped. Will add the confectioner's sugar when cool.
Finished..

P.S..this isn't a cheap dessert to make. I usually bake everything from scratch, but I love lemon desserts and wanted to give this recipe a try. The cans of lemon were about $3.69 each and the cake mix was just under $3.00.
What did I think of this dessert now that I've tried it....it's okay. I took a plate to my son's house and my son loved these squares. I guess I just prefer a slice of homemade lemon meringue pie or yellow cupcakes with lemon filling in the middle. To be truthful I didn't really care for these squares. I didn't like the texture..very spongy. I won't make this recipe again, but my youngest son loved them.
  my youngest granddaughters all decked out in red, white and blue. Bella 3 and Sammi 2 months. Below..I gave Bella a flag and she carried it around with her all afternoon.

Have a happy but safe 4th of July.
