Chocolate Sheet Cake -
A Cake To Remember

Straightforward easy chocolate sheet cake recipe, amazingly good.  Worth a try!

Chocolate Sheet Cake

A friend of mine made this chocolate sheet cake for her daughter’s birthday party and once Karolina came home she told me all about. 

She actually got excited over a chocolate cake.  I got this chocolate cake recipe the next day and tried it out immediately.    

Karolina was right.  It is delicious, light, sweet, and crunchy.  You just have to try it.  The high content of egg whites makes a crust on the top that combined with the walnuts just makes an excellent chocolate cake. 

Best of all, this cake is really fast and easy to make.  I had it in the oven in just under 20 minutes.  If you are looking for a quick chocolate cake recipe then you have to try this one, you will not be disappointed. 

Since I liked this chocolate walnut cake recipe so much, I wanted to share it with you and hopefully you will like it as well.  If you do, a “like” on Facebook would be greatly appreciated.

3.       Melt the chocolate with (2/3 cup) 120g sugar, butter and milk in a bowl suspended over simmering water.  You can also melt it in the microwave on high for 1 minute, take it out, and stir to melt everything else using the residual heat, like I did here.
