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…

And whisk them together.

A smooth, glorious batter will form.

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…

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 | www.cookiesandcups.com

And pour that frosting all over top!

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.

I made this Cake Last night because I’m a baker and wanted cake and something chocolate… with that being said OMG when I tell you it was the BEST HOMEMADE CHOCOLATE CAKE I’VE EVER MADE!!!! THE Heavens opened up with the first bite. Also when I cut a piece there was so much hot icing that it flowed down the cake (from where I cut it ) like lava WOW I will be making this cake again. This is a good one

I remembered that I didn’t have cocoa powder when I took the cake out and now it’s cooled, can I pour the boiled icing on cold cake?

I have just now seen the recipe and read the post. Interesting about the Crisco/Oleo comment in the post. Both of my parents grew up on a farm where fresh butter was the norm. Raising four children in town during the 50’s/60’s, real butter was not an option. My mother had to resort to “fake” butter–Oleo margarine. So, in my mind Crisco and Oleo are two different ingredients. I haven’t made the cake, yet, but 15-20 minutes for a 9″ x 13″ sheet cake doesn’t sound long enough. Most of my sheet cake recipes call for at least 30-35 minutes.… Read more »

Same thing happened to me. It came out like a dense brownie with frosting. The taste was good but not at all cake like and didn’t look like the pic.

I am making right now, and after 20 minutes in the oven the cake is really wet in the center. Going to let it cook another 10 minutes, and re-check, and cook a little longer if needed. Hopefully it doesn’t dry out.

I made this with a few tweaks (mostly because I messed up) and it is the best cake I have ever made. I am not a fan of chocolate but this will be craveable. My icing ended up having almost instead of vanilla and I topped it with coconut. So yummy I debating hiding it from the rest of my family.

I just made it and it took 50 minutes to bake! I kept checking every 5 min. The center was really jiggly even after 40 min.

Do you think I could make this a day in advance? I’d like to make it for Easter Sunday lunch, but I’d need to make it ahead on Saturday morning. Store in the fridge or out on counter?

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 🙂
