This recipe for the best thick chewy oatmeal cookies was sponsored by Cacao Barry. This easy recipe for oatmeal cookies is loaded with Alunga milk chocolate and salted peanuts, and the cookie dough can be made and baked right away without chilling the dough! 

What makes the best chocolate chip cookies? Or the best oatmeal cookie? This is such a loaded question and any answer goes because the truth is: my best oatmeal cookie recipe or perfect chocolate chip cookie recipe might not be your favourite. There are certain characteristics in a cookie that I look for that you might hate. The perfect cookie is subjective and the answers are infinite with no right or wrong.

Characteristics of the best oatmeal cookie (according to me)

1. should be a thick oatmeal cookie, not a thin cookie: I want minimal cookie spread and the cookie should have some heft to it
2. is a chewy oatmeal cookie: I don't want a soft oatmeal cookie, not that there's anything wrong with soft cookies, but I like oatmeal cookies that have a chewy texture with some bite to them
3. will have a slightly crackled top: the cracks on top of the cookie are what draw me in—I know the cookie is going to be good when I see those cookie cracks
4. is loaded with chunks chocolate, and I do mean chocolate, not raisins. There is a time and a place for oatmeal raisin cookies, but this is not a recipe for those. By the way, I have a recipe for crispy oatmeal raisin cookies if you need one
5. has both chocolate and nuts (salted peanuts work great!)—I hesitated to put nuts in these oatmeal chocolate cookies, but the salted peanuts are actually a really nice touch. You don't really notice the peanuts as you are chewing, but you can definitely taste them
6. made with vanilla: using pure vanilla extract in cookie dough adds depth, a little smokiness, and some musky flavour notes that would be missed if you skipped it. If you don't have any vanilla extract, try adding bourbon or rum as an alternative for those woodsy notes.

How do you make thick cookies that don't spread when baked?

The tricks to baking thicker cookies that don't spread when baked:

1. make a thicker dough with a higher proportion of dry ingredients and lots of add-ins (oats, chocolate, peanuts) which will impede cookie spread.
2. chill the dough before baking, which means it will take longer for the butter in the dough to "melt" in the oven. Cookie spread is a balance of melting and setting. Read all about why we chill cookie dough and what it does.
3. increase the baking temperature so that the exterior of the cookie sets before the cookie has time to spread.

How do you make cookies chewy?

1. Use brown sugar instead of white sugar because brown sugar will add a certain tenderness and softness to the dough while white sugar will lead to a crisp, dry cookie texture. Brown sugar also adds a lot more flavour which helps to balance out the flavour of the egg in cookies too! I like to bake with a mix of white and brown sugar for the perfect chewy cookie texture and sweet flavour.
2. Oats increase the chewiness of cookies by adding a texture to the cookie dough
3. Bake the cookies until they are perfectly golden brown but don't overbake the cookies and don't underbake the cookies either
   1. overbaked cookies will be dryer, hard, and crisper
   2. underbaked cookies will be softer, gooey-er in the middle
4. Avoid silicone bakeware for chewy cookies: silicone bakeware results in less browning and also in softer cookies. For soft cookies, use a silicone mat between the sheet pan and the cookies. For chewy or crispy cookies, use parchment.

Great chocolate makes awesome cookies so you MUST use the best chocolate for baking, a chocolate that you like to eat because this recipe is all about the chocolate. For this recipe, I made the milk chocolate ganache with Cacao Barry’s Alunga milk chocolate, which is sometimes referred to as dark milk chocolate because it has 41% cocoa solids, leading to a more complex, deeper chocolate flavour.

Alunga milk chocolate has a smooth, creamy texture and flavour that is not overly sweet, which is why even those that tend to prefer dark chocolate love it too. Alunga comes in 1-kilo resealable bags and is sold at IGA grocery stores in Quebec, as well as online via Vanilla Food Company.  The chocolate comes as “pistoles”, kind of like very large chocolate chips. I roughly chopped the pistoles to make these oatmeal chocolate chunk cookies. I have a post about the types of chocolate for baking if you need more info to guide you when you are shopping for chocolate to bake with.

Tools to bake the best cookies

There are tools, equipment, and bakeware that I use when I make cookies. The list is simple but if you are going to make cookies on a semi-regular basis, you might want to consider investing in a few items to make your baking sessions easier and more successful!

• Electric hand mixer: most of us used to make cookies with a good old wooden spoon, but now I don't have the stamina, arm strength, or motivation, honestly. I used an electric hand mixer from Braun (Multimix HM5100 available on Amazon) to make these cookies and it works well.
• Large bowl with a rubber or silicone grip on the bottom: if you are going to make cookie dough with a hand mixer, invest in a GIANT 8-quart stainless bowl with a rubberized bottom so it is stable on the counter and this way, the bowl won't dance around as the mixer runs. This set from Amazon will do the trick. Or buy a stainless bowl without a rubberized grip and nest it in a damp towel to stabilize it while mixing. 
• Kitchen scale: I cannot stress enough how much easier it is to measure baking ingredients by weight. If you are interested in making the switch to a digital scale, I like this OXO Good Grips kitchen scale available on Amazon. I use it all the time and it takes standard AAA batteries which you probably have on hand most of the time.
• Cookie scoop: this style of a cookie scoop, also known as a "disher" is the most reliable I've found (available on Amazon). They can handle firm doughs without breaking because the release mechanism is separate from the handle! This gives you a better, firm grip on the handle, without the risk of breaking the leaver.
• Baking sheets: I like to invest in large baking sheets, also known as half-sheet pans, with the following dimensions: 13"x18". I like the Nordic Ware sheets (available on Amazon) and they come in a variety of sizes (quarter sheet, half sheet, big sheet). You can also find cheaper pans. Just make sure you opt for light Aluminum pans, not the pans with a darker finish because cookies on darker pans will brown/burn more quickly on the bottom!
• Parchment paper to prevent sticking: I prefer to bake cookies on Aluminum pans lined with parchment paper. I have baked with Silpat and silicone baking mats in the past, but I much prefer baking with parchment. Silicone is insulating and this will have an impact on how long it takes to properly bake the cookies and this will reduce browning as well. If you like gooey, underbaked cookies, silicone mats like the Silpat are your best bet (available on Amazon). If you prefer chewy cookies, opt for parchment paper—I use the Kirkland brand roll available on Amazon.

If you ever run into the problem that your cookies are burning on the bottom and staying raw in the middle, it could be the material of your sheet pan (dark bakeware absorbs more heat), your oven temperature, or even too much baking soda in your recipe. And if you somehow wind up with too many cookies for you to eat, remember that you can chop them up into small pieces and freeze them for later so that you can fold them into a custard base to make a batch of cookie ice cream!
