Monster Cookie Ingredients & Substitutions

As always this recipe is gluten-free and vegan. That said, I do test each recipe with “regular” ingredients and make notes of alternatives or swaps so that everyone can enjoy it.

Gluten-Free Flour: I made these cookies with Kinnikinnick gluten-free all-purpose flour blend. Note that gluten-free flour blends can vary in weight so I recommend measuring by the cup. If you are not gluten-free, swap the flour with regular all-purpose flour.

Vegan Butter: I enjoy baking with Becel plant-based bricks but any vegan/dairy-free butter substitute will work. Use regular salted butter if you are not vegan or dairy-free.

Brown & Granulated Sugar: This combo creates the delicious taste and texture to these cookies. Coconut sugar, cane sugar, or even date sugar would work as well.

Peanut Butter: This recipe was made with smooth/creamy peanut butter like Jif, Kraft, or Skippy. It will also work with natural or crunchy peanut butter but will change the texture slightly.

Oats: Make sure the oats are certified gluten-free if you are a celiac. I prefer whole-grain rolled oats for the chewy texture but old-fashioned oats will do the job too. Do not substitute quick oats.

Flax Egg: To make this cookie vegan-friendly, I made it with two flax eggs. If you are not vegan or egg-free, you can swap in 2 large room-temperature eggs.

M&Ms: No Whey No No’s are a vegan, dairy-free, and gluten-free version of traditional M&Ms. Use regular M&Ms or any type of candy-coated chocolate treat if you are not needing to be dairy-free or vegan. *You could even sub in sprinkles for a fun twist.

Chocolate Chips: I love to bake with Pascha semi-sweet chocolate chips. You can use any type that suits your flavor and dietary preference.

How To Ensure Allergy-Friendly Monster Cookie Success

Let’s double-check all our cookie bases to ensure we have the most incredible life-changing gluten-free and vegan monster cookies.

Room temperature ingredients: For a smooth and fully incorporated cookie dough, room temperature ingredients are a must.

Cream the butter & sugar: To create these wondrously chewy cookies, creaming the butter, peanut butter, and sugars together until light and fluffy is key. Tiny little microscopic air pockets are being formed, which creates the delicious melt-in-your-mouth texture.

Don’t overbake the cookies: These gluten-free and vegan monster cookies are gloriously chewy because they are slightly underbaked when removed from the oven. The heat from the cookie pan will continue to bake these cookies after they come out so don’t worry about them being raw.

Fancy them up: Want a picture-perfect cookie? Garnish each cookie dough ball with additional chocolate chips and M&Ms before baking and then sprinkle on some coarse sea salt. Gorgeous!

Store & Freezing Instructions

Store these marvelous monster cookies in an airtight container at room temperature for up to 5 days. Likewise, they can be frozen in an airtight container for up to 6 months.

To freeze, I recommend scooping each cookie dough ball, give them a quick freeze on a tray, and then place into a large Ziploc freezer bag. This will allow you to pull out however many cookies you desire to bake at any time.

No need to thaw when you’re ready to bake, simply preheat the oven, pop them in, and bake for approximately 1 minute longer than the time listed below on the recipe card. Woohoo!

Monster Cookie FAQs

Can I add in different chocolate chips or candies?

Absolutely. Feel free to swap in whatever style of chocolate chip and/or M&M-type treat you like. I’ve even used sprinkles in these for a splash of fun. Go crazy!

How do I get perfectly round cookies?

Sometimes an errant chocolate chip or cookie edge will come out slightly wonky. Don’t sweat it. Use a butter knife or overturned glass to gently re-shape the edges as soon as they come out of the oven.

When do I know they are baked?

The edges will be a light golden and the center will appear to be slightly underbaked.
