Giant cookie cake
An easy recipe for a giant cookie cake, for when a regular sized cookie just isn’t enough! Kids will love getting to bake one of these.
Giant cookie cakes are the perfect bake for when a regular sized cookie just isn’t big en enough! This recipe is such a fun bake for kids – it’s colourful, delicious and really easy to make. It uses our favourite easy cookie recipe for kids, and rather than making lots of individual cookies you simply press it all into a cake tin. We’ve also added some colour with M&Ms rather than using chocolate chips.
How can kids help make a giant cookie cake?
This is a really easy cookie to make with kids as once you’ve made the mixture you just pop it in one big tin. There’s no scooping or forming individual cookies which makes it nice and simple and quick which is always something to consider when you’re baking with kids.
My kids always enjoy getting to measure everything out and then mix it all together to make the cookie dough. There’s also the chance to practice cracking an egg, which is an important kitchen skill for anyone to master.
Rather than scooping out the balls of cookie dough, your kids can simply help to press it all into our cake tin, and if you have very young children wanting to help, you could even get them to pop some extra M&Ms on top.
How long does a giant cookie keep?
Like any other cookie this giant cookie will keep in an air tight container for up to 5 days. If you want to keep it for longer you can freeze a giant cookie cake, either in one piece or individual slices. Simply wrap it well in cling film / glad wrap and pop it in a freezer bag. It will keep for up to three months once frozen.
How many does a giant cookie serve?
This giant cookie is 23 cm wide or 9 inches and serves 12 with quite generous portions. You could obviously cut the pieces smaller if you want to serve more people.

Ingredients
225g (1 cup) unsalted butter, softened
350g (2 cups) soft light brown sugar

½ tsp salt

how to make a giant cookie cake
Preheat the oven to 170C / 340F and line an 8 inch/ 20cm cake tin with baking paper.
Mix the butter and sugar
Get your child to measure the butter (225g) and sugar (350g) out then add to a mixing bowl or freestanding mixer. Mix them together using the paddle attachment, a hand held mixer, or wooden spoons until the eggs and butter are light and fluffy.
Add the eggs and vanilla extract
Get your child to break the eggs, one at a time, into a small bowl. Add them to your bowl, mixing it a little between each addition.
Turn the mixer down to a slower speed and get your child to help you measure the vanilla extract (1/2 tsp) into the bowl. Let them use the spoon on their own if they are able to, or help them and steady their hand while you pour if you need to.
Add the remaining ingredients
Measure the flour (400g) into a small bowl. If your child is able to, get them to help measure the salt ( ½ tsp) and bicarbonate of soda (2 ½ tsp) into the flour. Add these into your large bowl.
Mix everything together until you have a smooth dough. If you need to, use a spatula to scrape the mixture down from the sides of the bowl. We seem to have to do this a lot, especially to get the bits at the bottom, but it’s a good excuse to sample a wee bit of raw cookie dough as you go along!
Get the toddler to add the M&Ms, (keeping a few back to decoate later) to your dough mixture. Give it one last mix so that everything is nicely combined.
Make the giant cookie cake
Pour the cookie dough into your prepared cake tin.
Press down the mixture with the back of a spoon. If you need to, wet the back of the spoon to stop the cookie batter sticking too much. Sprinkle a few more M&Ms on top until it looks nice and colourful.
Bake the giant cookie cake
Pop the giant cookie in the oven for roughly 15-20 minutes. It’s ready when the edge has turned golden brown and they’ve flattened down. It’ll still be a bit gooey in the middle but that’s how I like them. Cook it longer if you prefer a more crispy cookie.
Leave it in the cake tin to cool slightly, then move it to a wire rack to cool completely.
Serve it and enjoy.

Lovely idea, however to anyone making this I think the measurements are slightly out or don’t convert well to us in the UK! Maybe your cake tins are a lot deeper, I couldn’t fit the mixture into a 20cm tin, so used 2 18cm, which I thought would be plenty. However it’s overflowed all over my oven! Hoping it will atleast taste good haha.
Oh no, I hope it didn’t make too much of a mess in your oven. What cake tins did you use and how deep are the sides? I’m UK based too and just used a regular cake tin, but the sides are a good few inches tall (you can see it in one of the pictures).
This is such a cute idea. My little guy would love it!
Thanks! My kids found it way more exciting than regular sized cookies! Let us know if you make it, we’d love to see the result.
