Sunday Chocolate Cake

Sunday Chocolate Cake with Boiled Frosting |

This Sunday Chocolate Cake is the easiest, most comforting chocolate cake recipe ever.  The boiled frosting on top is flaky, fudgy and delicious!


So this cake might not look like much, but let me tell you…it’s everything.

It simple.

It’s classic

It’s nostalgic.

And it has the best flaky boiled chocolate icing on top.


It’s a lot like a Texas Sheet cake, but better. It’s a lot like My Kid’s Favorite Brownies, but different…

I found the recipe for this in my Grandma’s recipe box and I remember her making it a lot.

She’d always make it on Sunday’s…hence the name.

It’s the perfect weekend cake.


Also, it’s my kid’s most favorite.  The classics usually are.

ps ~ Kristan made a super similar-but totally different cake over at her site today too!  The details are at the bottom of this post!


But first things first…

Sunday Chocolate Cake with Boiled Frosting |

This cake is easy. No mixer involved.  Love that!

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.

Oh yeah, add your cocoa powder in there too…

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…

Then whisk in your other wet ingredients until a smooth batter forms.

Pour that all in your prepared pan.

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

Boil butter, milk and cocoa powder together.

Then stir in some powdered sugar…

Whisk it all up until it’s smooth.

Pull the cake out of the oven when it’s done… Sunday Chocolate Cake with Boiled Frosting |

And pour that frosting all over top!

Then let the cake cool.

And your frosting will look like an old man’s wrinkly butt…

Ok, that was gross, I’m sorry.  And also, I haven’t ever seen an old man’s wrinkly butt in real life…but I did see that episode of Sex and the City.  YOU KNOWWWW!

Make it.  Your Sundays will be better for it.

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

Yep that is some serious chocolate goodness right there. I have never tried boiled icing but from that picture ; I am going need to try it soon on my cake!

January 9, 2014 8:42 am

Omg! My mom would always make a cake similar to this and she called it Texas Sheet Cake! So cool to see this, I’ll have to tell her

January 9, 2014 8:44 am

Now this is a cake my family would love!! Classics are the best and that icing! Wow, it sounds so good!

January 9, 2014 9:07 am

Boiled chocolate frosting is the best! I feel like it has magical powers. Reminds me of my mom’s recipe, and I’ll take this Monday-Saturday too!

January 9, 2014 9:32 am

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.

January 9, 2014 10:46 am

Both of these cakes look amazing!!! Thanks for sharing!

January 9, 2014 11:01 am

My hubs will love this cake!

January 9, 2014 11:07 am

January 9, 2014 12:05 pm

This looks sooooooo good! I’m definitely going to have to try it!

January 9, 2014 12:47 pm

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

January 9, 2014 2:29 pm

OK, is it just ME, or did anyone else Pin this one partly because of the “old man’s wrinkly butt” comment? I’m still giggling! 😀 Can’t wait to try the recipe! :)

January 9, 2014 2:30 pm

That’s very similar to our favorite chocolate sheet cake… love the boiled frosting!


A good old-fashioned chocolate cake…just what I’ve been craving!

January 9, 2014 3:14 pm

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!

January 9, 2014 3:25 pm

January 9, 2014 4:35 pm

January 10, 2014 12:31 am

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.

April 23, 2015 11:14 am

For the frosting can I use evaporated milk or is regular milk better? Also can the frosting be used on a 3-layer cake?

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.

January 10, 2014 6:16 am

I’m loving your grandmother right now. This cake looks a chocolate lovers dream come true. Love!

January 10, 2014 10:41 am

Ooh Ive never had boiled chocolate frosting but it is insanely mouthwatering! Love that theres no need for a mixer for this!

January 10, 2014 4:13 pm

I am drooling over this cake right now! It looks amazing yummy!

January 11, 2014 8:37 am

I’ve never made a boiled chocolate frosting before! Lovely!

January 11, 2014 2:43 pm

Heading to the store to buy the ingredients for this! Looks so amazing! Love a good chocolate wrinkly icing! Lol

January 11, 2014 10:58 pm

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!

January 12, 2014 5:19 pm

Made it last night…OMG…this will be a recipe I’m keeping in my stash! Such an awesome chocolate cake! Thanks!

January 12, 2014 10:23 pm

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.

January 14, 2014 7:56 pm

This looks so absolutely delicious and nostalgic. Seems easy. Will give it a go this month

January 15, 2014 3:21 pm

I made this today, the frosting came out perfect the cake not so much. It collapsed in the center. :(

January 17, 2014 6:57 pm

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

January 20, 2014 10:50 am

I want to jump in there and eat my way out. Totally.

Can I sub. skim for whole milk? I rarely have whole but almost always have skim. Thanks a bunch.

February 3, 2014 8:18 pm

I’m a little disappointed–I tried this recipe (using the butter for Crisco substitute and skim milk instead of whole) and by the end of 20 minutes of cooking my cake was still liquid! I ended up cooking for closer to 30 minutes, and when it came out it tasted like eggs. Any advice?

can i make this as a layer cake?

April 14, 2014 2:57 am

The icing turned out all right, too much powdered sugar for my taste though. The cake would not cook in the centre at all. I left it in for over thirty minutes and it still would not cook. Very disappointed as I was looking forward to making this cake.

April 15, 2014 9:00 pm

i used a metal pan instead of glass, and it was still not cooked at 23 minutes….wonder if i did something wrong?

April 16, 2014 10:06 pm

fyi. it took a while, but i pulled it out at about 28 minutes. it tastes delicious. i hope i can freeze it?

could you please put the oz and pounds or even grams it takes so long to work out the ingredients and i so love all your recipes thankyou x

June 19, 2014 11:20 am

This cake is really awesome, but I was scared to put 5 cups of powdered sugar into the icing. I made it with just one cup. It was still tasty, but of course looks completely different :) My son loved the cake and so do I :)

April 20, 2015 12:11 am

I just did the same. 5 cups of sugar was too much. In went just 1 cup Sugar just was yummy.(It was the frosting that drew me to this cake though) Will make it again for church.Also, I had Dutch processed cocoa so I went with Self Rising flour.

July 5, 2014 3:37 pm

Yummy! looks really good!

November 18, 2014 2:21 am


But where is the recipe? The link after your explanation does not work….


January 1, 2015 5:33 am

Hi, i want simple vanilla sponge cake recipe…

January 2, 2015 9:26 pm

Looks terrific! I’d double the amount of cocoa (from 1/4 cup to 1/2 cup) in the cake recipe – I like my cake more chocolatey :-)

March 29, 2015 9:58 am

Hi. Can u please tell ehat if i want to use oil omstead of butterand shortening? How much oil should I use.
