👻 Ingredients for Halloween Monster Bars

👻 Halloween Cookie Bars Ingredients
- All Purpose Flour: Use a bleach free one. Bleach in flour is no good! My all-time favorite flour is King Arthur Baking flour. Everything turns out so fluffy with this flour.
- Baking Powder: Aluminum free baking powder is the way to go. Avoid baking soda in this recipe as it will make it too dry.
- Brown Sugar: Coconut sugar also works well too! Just make sure it's a dark sugar and now white sugar or the cookie bars won't set right. We want these chewy cookie bars, not dry.
- Sea-Salt: I take a teaspoon of sea-salt per day to keep my mineral levels up and to keep me happy and hydrated. It has more uses than just for baking you know.
- Vanilla Extract: Bourbon Vanilla Extract is the only real vanilla extract you can find. Trust me, it makes ALL the difference. My fav brand is Trader Joe's.
- Melted Butter: Melt the butter until it turns into brown butter. This makes this halloween magic cookie bars legit magical!
- Eggs: Use organic, pasture raised eggs. Did you know that just because a carton of eggs says organic doesn't mean it's true? Pasture raised hens living outside with the American Humane Seal on the carton is the only way to go.
- Halloween Oreos: They are orange inside. I rest my case. 😉
- Halloween M&M's: Halloween M&M's add chocolate and vibrant color to this easy Halloween dessert.
- Pretzels: Pretzels are the salty part of these delicious halloween cookie recipe.
- Candy Corn: Candy Corn makes this dessert sweet with the classic Fall has arrived! Taste. Yes, there's a Fall taste, you know the one!
- Baking Dish: This one is Halloween themed. Enough said.
- Cooking Spray: Trader Joe's makes the best Organic Coconut Oil Cooking spray, but in a pinch this will do.
