What is a Cookie Cake?

A cookie cake is exactly what it sounds like – a giant cookie baked in a cake pan and sliced like a cake. It has all the flavour and texture of a classic chocolate chip cookie, but in a thick, shareable form.

This version is baked in a 9-inch round pan and makes 8 generous slices, though you can easily cut smaller portions if serving a crowd, or packing for a picnic.

Cookie cakes are incredibly popular for birthdays and celebrations because they’re easier than a traditional layer cake but still feel festive and fun.

Ingredients and Substitutions

This recipe uses simple baking staples that work together to create the perfect chewy cookie cake texture.

Ingredients for chocolate chip cookie cake: chocolate chips, flour, butter, salt, baking soda, egg, vanilla extract and white sugar.

Plant-Based Butter – This keeps the recipe dairy-free while still adding richness and flavour. Make sure to use block-style butter if possible, as it behaves more like traditional butter in baking. Substitution: Use dairy butter if dairy isn’t a concern.

White Sugar – Sugar sweetens the dough while also helping create those lightly crisp edges. Substitution: replace some of the sugar with light brown sugar for a slightly deeper caramel flavour and extra chewiness.

Egg – This helps bind everything together while adding structure and softness. Substitution: For a vegan option, use 1 flax egg, 3 tbsp aquafaba or 50g applesauce. Read more about egg substitutions in my Egg Substitutions in Baking Guide.

Vanilla Extract – Vanilla enhances the chocolate flavour and adds warmth to the cookie cake. Substitution: Use vanilla bean paste for a deeper flavour or swap with another extract for a different flavour twist.

All-Purpose Flour – Flour provides structure and keeps the cookie cake soft yet sturdy enough to slice. Substitution: Use a 1:1 gluten-free baking flour blend for an easy swap. I personally love Bob’s Red Mill Gluten Free 1:1 baking blend for this recipe.

Baking Soda – This helps the cookie cake spread slightly and creates that classic chewy cookie texture.

Salt – A little salt balances the sweetness and enhances the chocolate flavour. If you use salted butter, you can omit the salt.

Chocolate Chips – The star ingredient. Use your favourite dairy-free chocolate chips or chunks.

How to make the Chocolate Chip Cookie Cake

I love that this recipe uses a one-bowl mixing method to cut down on dirty dishes. You can either mix everything with a stand mixer or by hand with a wooden spoon or hand whisk.

Step 1: Prep the Pan.

Grease and line a 9-inch cake pan with parchment paper. This will help to release the cake more easily once baked.

Step 2: Make the Dough

Cream together the plant-based butter and sugar until light and fluffy. Add the egg and vanilla extract, then mix until fully combined.

Gradually add the dry ingredients (flour, baking soda, salt) to the wet ingredients, then fold in the chocolate chips.

The key is to not overmix and to stop when the dough is thick but still fully combined.

Step 3: Add Dough to the Pan

Press the dough gently into the pan. Important: don’t press the dough all the way to the edges. Leave a little space around the outside so the cookie cake can spread naturally as it bakes. This helps keep the surface flatter and more even once baked.

Step 4: Bake

Bake until the edges are golden and the centre is just set. And yes, you CAN bake this in your toaster oven, if you don’t want to use your main oven.

Once removed from the oven, the cookie cake will continue baking slightly as it cools.

I recommend running an offset spatula or knife around the outside of the cookie cake while warm, as this will make it easier to remove once cooled.

Step 5: Cool and Decorate

Allow the cookie cake to cool completely before decorating. I decorated mine with my stable chocolate buttercream, using a large star piping tip (1M) for that classic bakery-style finish.

Sprinkles
Mini Cookies
Crushed Candy
Fresh Berries

I added sprinkles to this one as my youngest always asks for them!

Baker’s Tips for Cookie Cake Success

Over my years of baking cookie cakes, I’ve picked up a few tips that make all the difference.

Don’t over-press the cookie dough – leave space for it to spread.
Don’t overbake – This is the most common mistake people make the first time they make a cookie cake. The centre should still look slightly soft when you remove it from the oven. Overbaking leads to a dry cookie cake, so keep an eye on it.
Cool completely before decorating – don’t rush to decorate as the icing will melt if you decorate too soon.
Use Room Temperature Ingredients – this helps the dough mix more evenly and creates a smoother texture.

Serving Suggestions

This cookie cake is delicious served as is, but there are so many fun ways to dress it up for summer gatherings and celebrations.

Serve Warm with Ice Cream – slightly warm a slice in the microwave and top it with vanilla ice cream (plant-based if needed) for the ultimate cookie dessert experience.

Add Fresh Summer Fruit – fresh strawberries, raspberries, or blueberries pair beautifully with the rich chocolate flavour and make this perfect for summer entertaining.

Create a DIY Dessert Bar – for parties and BBQs, set out toppings like sprinkles, chocolate sauce, mini marshmallows, whipped cream, and let everyone customize their own slice.

Decorating Ideas

One of the best things about cookie cakes is how easy they are to customize. Try decorating for:

Summer BBQs
Memorial Day
Canada Day
Father’s Day
Birthdays
Grad Parties
Baby Showers
Weekend Family Desserts

You can pipe borders, add messages, or keep it simple with a drizzle of melted chocolate and a handful of sprinkles.

Storage Tips

You mean you didn’t eat it all in one sitting? Willpower is a real issue for us with this recipe, but if you have leftovers, here’s how to store them.

Store the cookie cake in an airtight container at room temperature for up to 5 days.
You can also freeze undecorated slices to enjoy later. Simply thaw at room temperature before serving.

Common Cookie Cake Questions

Can I make this cookie cake ahead of time?

Absolutely – bake the cookie cake a day ahead, then decorate before serving.

My cookie cake has a ridge around the edge – what went wrong?

This is very common and easy to fix. This usually happens when there isn’t enough of a gap left around the edge when adding the dough to the pan. Next time, leave a bigger gap to allow for spreading.

Why does my cookie cake look raw in the middle?

Cookie cakes generally look softer in the middle, but it is completely normal and safe to eat.

Do I need a special pan to make this cookie cake?

No! A standard cake pan works perfectly.

I don’t have a 9-inch pan – what can I use instead?

You can easily use a smaller or larger-sized pan – a smaller one will give a slightly thicker cookie cake, whereas a larger pan will give a thinner cookie cake. Baking times may need to be adjusted slightly for different-sized pans.
