Over 10 years ago I was going through a Divorce. Instead of hiding away, I decided to Celebrate with a cheeky Divorce Party. One of the funniest highlights of the night was the Cake, not just any cake, but a hilarious Willy Cake! It became the centrepiece of the celebration, had everyone laughing, and reminded me that you can still find joy even in the middle of a difficult chapter.
This Cake Hack is Fun, Funny, and Delicious. Best of all, it’s Quick and Easy to make with hardly any ingredients. Whether you’re planning a cheeky Divorce Party or a Hens Party, this simple Willy Cake will be the star of the show.

My Divorce Party Story
This Willy Cake actually made its first appearance at my very own Divorce Party over 10 years ago. It was one of the funniest moments of the night and had everyone in stitches. I have shared more about that party, including my DIY decorations and other ideas, in this post: Divorce Party Inspiration. Here is a cheeky snap from that night:

You will love how simple it is to create this Penis Cake. With just a few store-bought items, you can put together a cheeky dessert that guests will be talking about for years. It is proof that sometimes the best party cakes are the ones that make people laugh out loud.
Ingredients
All of these ingredients can be found at your local supermarket. I usually grab mine from Coles, but you will find them almost anywhere:
- 1 x Jam Sponge Roll
- 2 x Chocolate Muffins
- 1 x Betty Crocker Strawberry Frosting (or flavour of your choice)
- 1 x Chocolate Ripple Biscuit
- Serving Plate or Platter
- Knife or Spatula for spreading the frosting

Directions
This cake comes together in minutes, with hardly any effort at all. Here is how to create the iconic shape:

- Place the Sponge Roll down the centre of your serving plate or platter.
- Use a small dab of Strawberry Frosting to stick the Chocolate Ripple Biscuit to the front of the sponge roll.
- Spread the remaining frosting evenly over the sponge roll with a knife or spatula.
- Position the Chocolate Muffins at one end of the roll to complete the shape.
And that is it. With just a few minutes of assembly, you have the perfect Willy Cake to surprise your guests:
