What is a cookie cake?

You know how eating one little cookie is just never enough? Well a cookie cake is the answer to that problem. It’s exactly like a cookie, only it’s:

  • HUGE – yep, this bad boy is baked in the oven in a 20cm round cake tin
  • crunchy on the top, soft and chewy on the inside – the size of a cookie cake means that you get the best of both worlds!
  • baked as one whole ‘cake’ so you don’t need to worry about rolling separate cookies
  • able to be decorated just like a real cake (this one has a yummy buttercream on top!)
  • fun, fun fun! Add chocolate chips, M&Ms, sprinkles… anything you like!

Luckily, the ingredients needed for our cookie cake recipe are super basic (you probably already have them in your pantry and fridge!):

  • butter
  • brown sugar
  • egg
  • vanilla extract
  • plain flour
  • bi-carb soda
  • sea salt
  • chocolate chips

One bowl, beaters (or a stand-mixer) and 10 minutes

It couldn’t be any easier to make a giant cookie cake… just a few minutes and 1 bowl is all you need. You can use hand-held beaters, a stand-mixer or a Thermomix… whatever you like!

  • Simply cream the butter and sugar together until pale and fluffy. Add the egg and vanilla extract and continue to beat. 
  • Turn the speed down to low and add the plain flour, bi-carbonate soda and sea salt and mix until just combined. 
  • Use a spoon to stir through the chocolate chips and M&Ms.

How to make buttercream frosting for a cookie cake

The best part about a cookie cake is that you can decorate just like a normal cake! In our giant cookie cake recipe, we used a basic buttercream frosting recipe with pink food colouring. 

Making homemade buttercream is so easy – and you only need 5 ingredients!

  • butter
  • icing sugar mixture
  • milk
  • vanilla extract
  • food colouring

To make the buttercream frosting, beat the butter in a bowl until pale and fluffy (approximately 5 minutes). Slowly add the icing sugar mixture, milk, vanilla extract and food colouring and continue to beat until smooth and creamy.

A cheats tip: using a sealable plastic bag (or glad bag) to add frosting

If you don’t own a frosting kit, don’t worry! Simply place your buttercream frosting into a sealable plastic bag, snip off a tiny section from one corner and squeeze the frosting through the hole. It’s such a super cheap and easy way to frost a cake!

And of course, once your cookie cake is baked and decorated… it’s all about adding some pretty little sprinkles on top!

    Hi I was just wondering if I could sub the egg in this recipe for something else at all?
