What IS Sunday Chocolate Cake?

So this cake might not look like much, but let me tell you…it’s everything. It’s simple, it’s classic, it’s nostalgic. AND it has the best flaky boiled chocolate icing on top.

I found the recipe for this in my Grandma’s recipe box and yes, she’d always make it on Sunday’s…hence the name. My Gram was a rule follower.

BUT it’s the perfect weekend cake. Or weeknight cake. Or afternoon cake…Also, it’s my kid’s most favorite.  The classics usually are.

What is fantastic about this chocolate cake recipe, is it’s SO easy. There is no mixer involved, which is always nice!

How to Make Sunday Chocolate Cake:

Go ahead and whisk your dry ingredients in one bowl and your wet in another…

Melt your butter and shortening in a saucepan…also, if you think vegetable shortening is from the devil go ahead and sub in all butter.  This recipe is my Grandma’s back in the days where Crisco was king.  Actually the recipe calls for Oleo, so yeah. I’ve made it will all butter and it’s delicious.

Next add unsweetened cocoa powder.

Also, I am the messiest cocoa powder user ever in existence. What’s my problem??

When it’s all melted pour it into your dry ingredients…

Pour that all in your prepared pan.

When the chocolate cake is almost done baking, start making your boiled frosting.

Boil butter, milk and cocoa powder together in a medium saucepan, and then stir in some powdered sugar…

Glorious.

Allow the cake to cool, and your frosting will look like wrinkly. It’s ok…in this case wrinkles are good.

This is easily the most made cake in my house, along with my easy cinnamon roll cake. Not having to worry about making layers and piping frosting makes cake baking so much more of an everyday type of dessert.

Your Sundays will be better for it.

Also, the edge pieces are my favorite.  All the frosting.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

  1. Um, is it possible to use cocoa WITHOUT making a mess? I’ll try to neatly scoop cocoa and all of a sudden there’s chocodust everywhere! Maybe I’m just messy cook in general, and I just notice the cocoa more because it contrasts with the counter.

  2. Recipes like this, straight from Grandma’s recipe box, are always the best. Especially with the memories you have of it! I love the nostalgic taste of TX sheet cakes and I know this would be right up there too! That frosting just looks awesome! pinned

  3. OK boiled, flaky chocolate frosting is the BEST! I haven’t had it in God knows how long because nobody makes it like that anymore. And I once described my idea of perfect frosting to a friend, and it was JUST THIS! Love!! I want some so badly now!

    my mom made this recipe and she was always told it was the texas sheet cake and she would say no and said she got the recipe out of a local paper, and it was for a 9 x 13 cake pan, not a sheet pan. Its the cake all my bros and sis want when we get togetheer.

      1. Shelly

        You could use evaporated if you would like! It will be a bit bit thicker, but that’s ok! The frosting is a bit thin for a layer cake, so if you’re looking for a thinner frosting that’s good. You could let it cool a bit more and it will thicken up to spread.

    This is the recipe I also call Texas
    sheet cake. Or “our” chocolate cake- because it’s been our go to choc cake recipe for over 40 yrs now. You just CANNOT beat it, according to our family. That wrinkly old icing is simply the best. Loved your description! Lol.

  6. Ashleigh

    I cooked it for the 12 – 15 minutes but it wasn’t ready. Is this the correct time?
    Awesome recipe – it makes me look organised!

      1. Karen

        I had to cook it for 35 minutes on 400 degrees. After 20 minutes, the middle was still jiggly. It’s a pretty thick cake!

  7. Kristen

    Hi Shelley,

    My Grandmother used to make this cake for every church event when I was growing up. It is SO good! She sprinkled pecan halves on hers before she poured the icing. Thanks for posting a oldie but goodie.

  8. I’m baking this right now! Smells really good, and I decided to taste the batter before pouring it on the pan, and it tasted GREAT!! I’m excited, and so is everyone else in here lol
