Chocolate Sheet Cake


Chocolate Sheet Cake

I am super excited for this post today.  September marks the 1 year anniversary for the #chocolateparty.  To help celebrate,  Roxana has lots of great stuff up for grabs.  Like seriously, you need to read the bottom of this post and enter the giveaways.  Kind of wish I wasn’t participating this month, so I could enter.

Chocolate Sheet Cake

To celebrate the first anniversary Roxana as that some of share our families favorite chocolate recipes.  She made them all too, and has been sharing them all month long.  There have been some amazing chocolate desserts that are now on my list of must tries!  Like this Nutella Gooey Butter Cake, holy cow does it look good.

Chocolate Sheet Cake

For the party I made my families Chocolate Sheet Cake recipe.  We have been making this since I was a little girl.  It was a staple at many birthday parties and often times just a treat on the weekend.  This was my first time actually making the cake.  Usually my mom makes it, and I just get to eat it!  This time, I turned the tables and made it for my family when they were here visiting.  I have to say, it tasted just like my moms.

Chocolate Sheet Cake - a traditional rich, chocolate, Texas style sheet cake.



  1. I had so much fun seeing all of the chocolate recipes. I am sad to see it end.

  2. This cake looks like chocolate heaven!

  3. Hi Erin,
    Thank you for sharing your recipe with me. Few weeks ago was the first time I made a sheet cake and although I actually made yours in a 13X9 pan next time I will use a sheet pan so it turns out just like yours.
    Thank so much for being so supportive since the first #chocolateparty last year and I hope you’ll join us for many parties from now on

  4. You had me at chocolate.

  5. The recipe for the sour milk doesn’t make sense to me. Both recipes call for 1/2 cup yet the recipe at the bottom indicates 1/3 cup. Clearly I am missing something. I guess all of you can “duh” me when explaining. :)
