Pans to Bake In
You can make this cake in just about any baking dish – a couple pretty pie dishes, a sheet pan, pizza pan, tart pan, brownie pan or even Pyrex. J
ust reduce baking time for thinner cakes and remember my secret to a really great cookie cake – always under bake. Under baking gives it that melt-in-your-mouth chewy texture that makes it memorable.
I’ve received so many requests for this heart shaped tart dish, and I’m so thrilled to share that it’s finally available again. You can get this darling heart pie dish here though and half the recipe. Of course you can use any pizza, cake or casserole dish as well.
Cookie cakes are so delicious, kids and adults alike always enjoy them! I love them because they’re quick, easy, foolproof and look beautiful without any effort.

Decorating Ideas
Feel free to decorate this cake however you like! For me, a few sprinkles and a pretty dish make this cake beautiful in all it’s imperfections (I’ve never excelled at frosting) and candles ready for birthday celebrations. But you can easily adapt the cake with colored icing and whatever add ons fit your celebrations!
Tips
- Bake time will vary depending on the pan you use. Reduce baking time for thinner cookie cakes checking in at 15 minutes and increase for thicker cakes if you want them more done.
- Let the cake completely cool before adding the frosting to prevent it from melting off.
How to Store
- Room Temperature – Store covered or in an airtight container up to 2 days at room temperature.
- Refrigerate – Store in an airtight container up to 5 days.
- Freeze – Freeze without frosting wrapped with plastic wrap and in an airtight container for up to 3 months. Bring to room temperature and frost.
