How to Make Spooky Halloween Oreo Cake Bars

1. Preheat your oven to 350 °F (175 °C) to ensure it s nice and hot for baking. Prepare two 9×13-inch baking pans by greasing them or lining them with parchment paper for easy removal.
2. Mix the cake according to the package instructions, which typically includes adding eggs, oil, and water or milk. This creates a light, fluffy batter that serves as a perfect base for your bars.
3. Fold in the chopped Halloween Oreos, chocolate chips, and half of the sprinkles into the batter gently. This will distribute the add-ins without deflating your lovely cake base.
4. Divide the batter evenly between your prepared pans. Top with the remaining sprinkles and press candy eyes into the batter; this will help them stay visible and fun once baked!
5. Bake for 25-30 minutes until a toothpick inserted comes out with a few moist crumbs. The top should be slightly golden brown and inviting.
6. Cool the bars completely before cutting them into squares. This step is essential for clean cuts and to let the flavors meld beautifully together.

Optional: Dust with powdered sugar for an extra spooky touch!
