St. Patrick’s Day Deep Dish Cookie Cake Recipe

Although we don’t generally celebrate St. Patrick’s day in our house it’s really fun to come up with ideas, and sweet treats for the whole family to enjoy!

My husband and I have been working together at this baking/photography thing for the blog and this time around we came up with a delicious Cookie Cake that is perfect for St. Patrick’s day and I am so excited to share it with you today.

I was really worried about making it look St. Patrick’s enough – but I think we nailed it. I am so happy with how it looks, and my kids think its the best thing they’ve ever seen because hello, look at all the fun on this thing!

We have homemade little dollar coins/pots of gold, we have sour rainbow straps, delicious homemade buttercream frosting and crunchy green M&M’s throughout the cake! Talk about a whole lotta yum!


  • 1 cup softened margarine or butter
  • 3/4 cup white sugar
  • 1 1/3 cup medium packed brown sugar
  • 2 eggs
  • 2 1/2 tsp vanilla extract
  • 3 cups all-purpose flour
  • 2 1/2 cups green mini m&m crisps
  • 1 1/2 tsp baking soda
  • Salt to taste (1/4 tsp)


  1. Preheat oven to 325
  2. Grease a 12-inch deep frying pan or use a quality vegetable spray
  3. In your stand mixer, combine margarine and sugars, mix on med speed until fluffy and hold a sheen
  4. Add eggs one at a time making sure to fully incorporate each egg
  5. In a separate bowl, combine all dry ingredients less the greens
  6. Slowly mix the dry ingredients into the wet ingredients until just mixed.
  7. Fold in your greens and dump into your frying pan
  8. Give the batter a good spread making sure to wet your spatula on your last few passes to ensure a nice even top
  9. Bake for 30-35 mins let cool completely before decorating

Whipped Topping Ingredients:

  • 1 cup heavy cream
  • 2 tbsp sugar
  • 1/2 – 1 tsp vanilla or any flavour of your choice
  • 13 drops blue 16 drops yellow food colouring or until your Color reaches the depth you’d like

Whipped Topping Directions:

  1. Chill your mixing bowl in freezer for about ten minutes.
  2. Add 1 cup heavy cream and beat on high until soft peaks form
  3. Add in sugar, factoring and blue only. Once blue is fully incorporated (scrape bottom and sides of bowl), turn on low and add yellow.
  4. You can stop whenever you reach your desired shade Fill a piping bag with a star fitting and pipe away
  5. Add your decorations as you wish. We used rainbow sour straps and homemade dollars/pots of gold which was melted down caramel chocolate chips with yellow sugar sprinkles in a round ice cube tray (put in the freezer for 20 minutes and you are good to go!)

This delicious cookie cake can be made in any pan or skillet, it’s more like a deep dish cookie… so it’s fun to make it in whatever you can to keep it deep enough to be deep dish.

We used a regular ol’ frying pan, as I don’t have a skillet at the moment. It slid right out after and was quick and easy to cool down to decorate just how we wanted it for the occasion!

Even if you don’t celebrate St. Patrick’s day think about taking something like this to a get together, pot luck or even in to the office as a cheery little treat for your co-workers (or neighbours if you are like us and work from home!) it’s a fun treat and big enough to share!

Top with a little bit of french vanilla ice cream or leave it plain, as it’s just as delicious without the ice cream! We will be making this often as now our kids request it! They even wanted to take pieces of it to school but, we limit the sweets and just made sure they all had a sliver to enjoy – and boy did they ever!
