How to Prepare Your Giant Christmas Cookie: Step-by-Step Instructions
Preparing the Dough for the Giant Christmas Cookie
Alright, let’s get this Giant Christmas Cookie dough going! First, preheat your oven to 180C/160C fan. Don’t skip this! Line an 8 inch/20cm round tin with parchment paper. Trust me, it’ll save you a headache later.
Now, melt that butter in a big bowl. Microwave works great, just don’t let it explode! Add in both sugars – the white and the brown – and whisk ’em together for about 2 minutes. You want it smooth, like a sugary paste. Then, crack in the egg, add the vanilla, and whisk again. Just until it’s smooth, okay? Don’t overdo it!
Next, dump in the flour, bicarb, salt, cornflour, ginger, cinnamon, and nutmeg. Mix it all together until BAM! Cookie dough. If you’re overmixing, it’ll get tough. So, easy does it! Finally, toss in those chocolate chips and chunks. Give it one last mix, and you’re good to go!
Baking Your Giant Christmas Cookie
Okay, time to bake this bad boy! Press the dough into the bottom of your prepared tin, and flatten it out. It should be nice and even. Pop it in the oven for 25-27 minutes. Keep an eye on it! You want the top to look “dry.” Don’t worry if it’s still a little soft; it’ll firm up as it cools.

Now’s the time to add sprinkles! Carefully press them into the top. Then, let the Giant Christmas Cookie cool in the tin for about 30 minutes before moving it to a wire rack to cool completely. This is important! Don’t rush it, or it might crumble.
If you’re using a bigger tin (9 inch/23cm), bake it for a bit less time – around 20 minutes. It’ll be thinner, but still just as delicious!
Decorating Your Giant Christmas Cookie
Frosting time! This is where the magic happens. Beat that room-temperature butter for a minute or two until it’s nice and soft. Then, add the icing sugar, vanilla extract, and green food coloring. Beat it all together until it’s smooth and creamy. If it’s too thick, add a tiny splash of milk. If it’s too runny, add more icing sugar.

Now, grab a piping bag (or a ziplock bag with the corner snipped off) and pipe that frosting around the edge of the Giant Christmas Cookie. Get creative! Swirls, stars, whatever you like! Finally, add those sprinkles and any other decorations you fancy. Mini marshmallows? Chocolate shavings? Go wild!
And there you have it! A gorgeous, festive, and totally shareable Giant Christmas Cookie! Now, try not to eat it all yourself!
Tips for the Perfect Giant Christmas Cookie
Want to make sure your Giant Christmas Cookie is a total success? Here’s the lowdown! First, room temperature ingredients are your friend, especially for the frosting. Don’t overbake it! A slightly soft center is way better than a dry, crumbly cookie. And PLEASE, let it cool completely before frosting. I know it’s tempting, but trust me on this one! It’ll be worth the wait!
Ingredient Notes and Substitutions for Your Giant Christmas Cookie
Okay, so, a couple of things about the ingredients for this Giant Christmas Cookie. That cornflour? It makes the cookie super soft, but if you don’t have it, just add a bit more flour. It’ll still be yummy! And the chocolate? Go wild! Milk, dark, white… whatever you fancy. If you want to make it extra chocolatey, swap some of the plain flour for cocoa powder! Just play around and have fun!
Storing Your Giant Christmas Cookie
So, you’ve baked this amazing Giant Christmas Cookie… and somehow, you have leftovers?! Wow! To keep it fresh, store it in an airtight container at room temperature. It’ll be best eaten within a day or two, but it’ll still be pretty darn good for up to 4-5 days. If it starts to dry out, warm it up a little – that always helps!
