Katherine Sabbath Inspired Birthday Cake

cake katherine sabbath inspired30th birthday cakeTwo weeks ago I celebrated my 30th birthday. The celebrations seemed to last for  days, which I was more than happy with. My birthday fell on a Wednesday and in the months leading up to the date I ummed and ahhhed about whether to have a party or not. Not enjoying being the center of attention, a party seemed to be a bit too much. But after much deliberation I realised what better excuse do you have to catch up with friends from far and wide. Also I really wanted to make a cake!

I began researching my cake about a month before the big day and found some amazing resources.

decorated layer cakeI cooked 2 of Katherine Sabbath’s Chocolate Mud Cake on the Friday before the Sunday afternoon party. I wrapped them well with Glad Wrap and stored them in the fridge.

4 layered chocolate mud cakeDecorations consisted of peanut brittle (I used glucose syrup in place of the light corn syrup), salted caramel covered popcorn, honey comb, chocolate coated pretzels, jersey caramels, and some peanut brittle dust.

To make the peanut brittle dust, once I’d set aside some shards to decorate the cake with I put the rest into the food processor and ground it until it was as fine as I was after. I also used this in between the layers of the cake.

Katherine Sabbath inspired cakeI needed the cake Sunday mid-day, and knew I didn’t have most of Saturday to cook, bake or construct. This is my baking timeline:

Thursday: Salted Caramel Popcorn, Peanut Brittle, Peanut Brittle Dust, Chocolate Covered Pretzels, Condensed Milk Dulce De Leche

Friday: 2 x Chocolate Mud Cake (recipe at end of the post)

Sunday: Salted Caramel Swiss Meringue Butter Cream (I followed this recipe, then once all the butter was incorporated, I added 1/3 cup of the Dulce De Leche and mixed until correct consistency was reached), Chocolate Ganache, Construct and Decorate


I started by leveling the top of the cakes with our large bread knife, then cutting each cake into two horizontally (I love this tutorial for cutting the cakes and then to show you how to do a crumb coat).

On the cake board I smeared a small amount of Dulce De Leche to hold the initial cake to the board, then on went the first cake, on top of the I smeared some more Dulce De Leche, sprinkled some peanut brittle dust and then did a layer of the Salted Swiss Meringue Butter Cream. I repeated this until all layers were on the cake. Then into the fridge it went to set.

I then did a crumb coat over the whole cake and returned the cake to the fridge. Finally, I did the last layer of Swiss Meringue Butter Cream, making it as even as I could around the cake and returned it to the fridge before covering in ganache and decorating.
