How to Make Chunky Halloween Treat Bars

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Prepare an 8×8-inch baking dish by greasing it lightly with nonstick spray or lining it with parchment paper for easy removal later.

Step 2: Combine Dry Ingredients

In a large mixing bowl, toss together rolled oats, chocolate chips, chopped nuts, and pumpkin spice. Make sure they’re evenly mixed so every bite offers a taste explosion.

Step 3: Melt Peanut Butter

In a microwave-safe bowl, gently melt the peanut butter until it’s smooth—about 30 seconds should do it. Stir in mini marshmallows until they start to soften slightly; this creates gooey goodness throughout the bars.

Step 4: Mix It All Together

Pour the melted peanut butter mixture over the dry ingredients. Stir well until everything is coated evenly. Get your hands in there if necessary—this is where the fun happens!

Step 5: Transfer to Baking Dish

Spread the mixture evenly into your prepared baking dish using a spatula or your hands (yes, go ahead!). Press down firmly so they hold together during baking.

Step 6: Bake and Cool

Bake in your preheated oven for about 20-25 minutes or until golden brown around the edges. Allow them to cool completely before cutting into squares—if you can resist the temptation!

Serve these Chunky Halloween Treat Bars at your next gathering or simply enjoy them as an afternoon pick-me-up while binge-watching spooky movies. They’re sure to delight both kids and adults alike!
