There is something nostalgic for me about a monster cookie. Growing up, my mom used to make these for a church picnic, a youth event or for a family gathering. We rarely came home with many cookies if any. When it comes to a delicious treat, these Monster cookies cannot be beat for sharing.
TIPS FOR MAKING THE BEST MONSTER COOKIES
- Use creamy peanut butter that is no stir. Natural peanut butter will not make the cookies turn out as well.
- Which oats to use? Rolled oats do work, however they make for a cookie that cmay crumble a little easier. Quick oats may be the better choice.
- Mix with an electric mixer or a large stand up mixer. With this cookie being a larger batch recipe, using a mixer works well.
- Use butter not coconut oil or olive oil. Butter has the best taste and consistency for this cookie recipe.
- These cookies can either be frozen as the dough balls and baked later or baked and frozen. Store them in a ziplock bag or airtight container for up to 3 months.
- If this recipe is too much in volume, feel free to cut the recipe in half.
