Ingredients
To create these delightful Halloween Frosted Sugar Cookie Bars, you’ll need:
For the Cookie Bars
- 1 cup salted butter, softened
- 1 cup granulated sugar
- 2 tsp vanilla extract
- 1 egg
- 2 ¼ cups all-purpose flour
- 2 tsp baking powder
For the Frosting
- ½ cup salted butter, softened
- 2 cups powdered sugar
- 2 tsp vanilla extract
- 2 tbsp heavy cream
- Orange food coloring (optional)
- Sprinkles (optional)
How to Make Halloween Frosted Sugar Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F. This ensures that your cookie bars bake evenly from the moment they go in.
Step 2: Prepare Your Pan
Line a 9×13-inch baking pan with parchment paper. This will help prevent sticking and make it easier to remove the bars after baking.
Step 3: Make the Dough
In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add in the vanilla extract and egg, mixing until well combined.
Step 4: Combine Dry Ingredients
Gradually incorporate the all-purpose flour and baking powder into the wet mixture. Stir until a soft dough forms.
Step 5: Bake the Bars
Press the cookie dough evenly into your prepared baking pan. Bake for 14-16 minutes or until the edges are lightly golden. Allow them to cool completely in the pan on a wire rack.
Step 6: Prepare the Frosting
In another bowl, beat together softened butter, powdered sugar, vanilla extract, and heavy cream until smooth peaks form.
Step 7: Color Your Frosting
If desired, add drops of orange food coloring to your frosting. Mix until you reach your preferred shade of orange.
Step 8: Frost Your Bars
Spread the orange frosting over your cooled sugar cookie bars.
Step 9: Add Some Fun!
Sprinkle festive Halloween sprinkles on top for decoration before serving.
Step 10: Cut and Serve
Once the frosting has set slightly, cut into squares and enjoy immediately or store for later!

How to Perfect Halloween Frosted Sugar Cookie Bars
To ensure your Halloween Frosted Sugar Cookie Bars come out perfectly every time, follow these helpful tips.
Use Room Temperature Ingredients: Allow butter and eggs to come to room temperature for better mixing and texture.
Measure Flour Correctly: Spoon flour into your measuring cup and level it off. Avoid packing it down to prevent dense cookie bars.
Don’t Overmix the Dough: Mix until just combined. Overmixing can result in tough cookie bars.
Cool Completely Before Frosting: Let the cookie bars cool completely before adding frosting. This prevents melting and maintains the frosting’s shape.
Customize Your Sprinkles: Use themed sprinkles that match your party decor for added flair and fun!
Best Side Dishes for Halloween Frosted Sugar Cookie Bars
Pair your Halloween Frosted Sugar Cookie Bars with these delightful side dishes that complement their sweetness and enhance your Halloween spread.
Pumpkin Soup: A creamy pumpkin soup garnished with toasted pumpkin seeds offers a warm contrast to sweet cookies.
Spooky Cheese Platter: Serve various cheeses with crackers and fruits, arranged in fun shapes like ghosts or pumpkins.
Apple Slices with Caramel Dip: Fresh apple slices paired with rich caramel dip create a refreshing balance to the dessert.
Vegetable Tray with Hummus: Crunchy veggies served with hummus provide a healthy option that contrasts nicely with sweet treats.
Mini Corn Dogs: These bite-sized treats are always a crowd-pleaser at parties, providing savory goodness alongside sweets.
Popcorn Balls: Sweet and salty popcorn balls can be shaped into festive forms like pumpkins or ghosts for added fun.
Common Mistakes to Avoid
When making your Halloween Frosted Sugar Cookie Bars, it’s easy to make a few common mistakes. Here’s how to avoid them:
- Overmixing the dough: Mixing too much can lead to tough cookie bars. Mix just until the ingredients are combined.
- Skipping the cooling time: Cutting the bars before they cool can result in a messy treat. Be patient and let them cool completely before slicing.
- Not measuring flour correctly: Too much flour can make your bars dry. Use the spoon-and-level method for accurate measurement.
- Using cold butter: Cold butter won’t cream well with sugar, leading to a dense texture. Always use softened butter for best results.
- Ignoring oven temperature: An oven that’s too hot can burn the edges while leaving the center undercooked. Use an oven thermometer to ensure accuracy.
