Oatmeal Cookie Pie is a giant oatmeal cookie baked in a pie plate – a pizookie! This easy cookie recipe is full of chocolate chips, pecans, oats, and cinnamon – it’s all the best things in one big giant cookie!

Have you ever eaten a dessert and had it change your life? This dessert did that for me. I ate way too much of this Oatmeal Cookie Pie myself. Way. Too. Much. Because it’s that good. What’s a girl to do when she bakes a warm, gooey oatmeal cookie in a pie plate, a cookie that’s filled with chocolate and pecans, and then she tops it with ice cream and takes photos? Just let it sit? Or attack it with a fork? (If you didn’t say “attack it with a fork” I don’t know if we can be friends anymore.)

If you don’t feel like scooping or chilling cookies, or you don’t want to make a normal cookie cake, then make THIS. Serve it with ice cream and chocolate sauce and you have the perfect dessert!

Because really. Look at that cookie: would you have been able to walk away from it?

Ingredients Needed

  • Butter: I always use unsalted butter – be sure it’s room temperature.
  • Sugar: A combination of granulated sugar and packed brown sugar.
  • Quick Oats: These make a chewy oatmeal cookie that’s less hearty than with rolled oats. Make your own quick oats if you only have old fashioned.
  • Pecans and Chocolate Chips: I love both in cookies so I didn’t want to choose!
  • Cream butter and sugars in a large mixing bowl (use a stand mixer fitted with the paddle attachment if you have one). Mix in egg, vanilla extract, baking soda, salt, and flour, then mix in oats. Stir in pecans and chocolate chips.
  • Press cookie dough in a 9-inch pie plate. Bake at 350°F until light golden brown.

How to serve a pizookie

This Chocolate Pecan Oatmeal Cookie Pie is a show-stopper dessert. It’s one of those things that’s so easy to make but is so decadent everyone will oooh and aaaah over it.

Really, anything you serve warm with ice cream pooling all over the top will get some ooohs and aaahs but this? Takes the pie.

This is best served warm, with ice cream, and eaten straight from the pan. You can bake it ahead of time and reheat it before serving. You can serve it as slices or not, up to you. If you prefer individual servings, try baking 1/4 cupfuls of dough in muffin pans. Top with a scoop of ice cream and you’ve got a perfect after dinner treat.

Expert Tips

  • The cookie is done when it’s light golden brown on the outside. The inside will stay gooey.
  • Use any mix-ins you like. You can omit the nuts if you don’t want to use them.
  • If you plan to serve slices, let it cool completely before slicing.


Can you freeze a pizookie?

Freeze this cookie pie tightly wrapped with plastic wrap for up to 3 months.

  1. Okay, so on the one hand I wish we lived closer….and on the other hand I’m so glad we DON’T! I would not be able to resist all your delicious treats!!!!

  2. I am so glad you thought of making a skillet cookie in a pie pan! ( and such a mouth watering one too!) So obvious, yet I sure didn’t think of it. 🙂 I have been sighing over skillet recipes for ages, because I don’t have a skillet. My skillet/pie pan debut will be this amazing cookie! Thank, Dorothy!

  3. I have been waiting for a recipe like this that does not use a skillet! Because I only have a small skillet, and that clearly would not work for the amount of cookie that would be required. But pie plate? Why didn’t I think of that? I want to make this right now. I keep saying I am going to stop eating sugar. Then I come here. What’s a girl to do?

  4. I have always wanted to see their test kitchens! Bet it was a lot of fun girl and this pie, I need this in my belly asap!

  5. Life-changing indeed! That’s how I feel about that ice cream. It’s amazing! And this cookie pie? Even better. I love the combination of flavors and textures happening here. I totally wish I had some for lunch! 

  6. Yum – warm cookie pies with ice cream on top is the BEST! This looks super tasty!! Pinned 🙂

  7. This warm, gooey oatmeal cookie looks yummy! “life changing” desserts are always the best!

    This will go on my to do list for sure. Pinned!

  8. I imagine this was like that scene from Sex and the City, where Miranda eats, leaves and keeps coming back and eats an entire chocolate cake?! girl, I would have done the same thing. First off. .  a chocolate pecan oatmeal big ass cookie?!!! and the salted caramel butter pecan ice cream?!!!!! oh my gawd, I want it ALL!!!!! love this! 

  9. Ok, so I would totally attack this cookie and not be able to stop!!!  Holy cow!!!  And that ice cream…dying is what is happening right now.  How fun that you got to visit their kitchens and see all the fun behind the scenes!
