How to Make Halloween Sugar Cookie Bars

Step 1: Prepare your oven and pan

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it for easy removal.

Step 2: Mix dry ingredients

In a medium bowl, whisk together the all-purpose flour, baking powder, and salt until well combined.

Step 3: Cream butter and sugar

In a large mixing bowl, beat the softened unsalted butter with granulated sugar until light and fluffy, about 2-3 minutes.

Step 4: Add wet ingredients

Beat in the eggs one at a time, followed by vanilla extract until fully incorporated and smooth.

Step 5: Combine dry and wet mixtures

Gradually add the dry ingredient mixture into the wet ingredients, mixing gently until a soft dough forms. Avoid overmixing to keep bars tender.

Step 6: Bake the bars

Spread the dough evenly into the prepared pan. Bake for 20-25 minutes or until the edges turn golden and a toothpick inserted comes out clean.

Step 7: Prepare the frosting

While the bars are baking, combine powdered sugar with milk or cream to create a smooth, spreadable frosting. Adjust the liquid to achieve your preferred thickness.

Step 8: Frost and decorate

Once the bars have cooled completely, spread the frosting evenly over the top. Sprinkle generously with your favorite Halloween-themed decorations for colorful festive fun.

Pro Tips for Making Halloween Sugar Cookie Bars

• Use room temperature butter: Makes creaming with sugar easier and yields a lighter texture.
• Don’t overbake: Keep an eye on the bars to retain softness and avoid a dry texture.
• Chill dough if needed: If your dough feels too sticky to handle, chilling for 15-20 minutes can help.
• Cool completely before frosting: Prevents the frosting from melting and sliding off.
• Get creative with sprinkles: Use different shapes, colors, and edible glitter to enhance the Halloween theme.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Keep leftover Halloween Sugar Cookie Bars in an airtight container at room temperature for up to 3 days to maintain freshness and softness.

Freezing

You can freeze unfrosted bars wrapped tightly in plastic wrap and foil for up to 2 months; thaw completely before frosting and serving.

Reheating

Warm refrigerated or thawed bars slightly in the microwave for 10-15 seconds to soften before enjoying, but avoid overheating to keep the frosting intact.

FAQs

Can I make these bars gluten-free?
