M&M Cookie Bars Recipe FAQs
What type of M&M candies should I use?

How do I store M&M Cookie Bars?

What should I do if my cookie bars are too crumbly?
Very! If your M&M Cookie Bars turn out crumbly, it may be due to overmeasuring your flour. Make sure to spoon and level the flour rather than packing it into the measuring cup. Also, ensure that your butter is at the correct softness; too hard or too melted can affect the texture. If crumbly, you can drizzle a little milk to help bring them together before cutting.
Are M&M Cookie Bars safe for pets?
Definitely not! While M&M candies are delicious for us, they contain chocolate and sugars that can be harmful to pets. Always keep these tasty treats out of their reach to ensure their safety, and opt for pet-safe snacks to share with your furry friends.
Can I substitute any ingredients in the recipe?
Absolutely! If you need a gluten-free option, you can substitute the all-purpose flour with a 1:1 gluten-free flour blend. For a dairy-free version, replace the butter with coconut oil or a vegan butter substitute. Make it your own and enjoy the baking process!
