Halloween Sugar Cookie Bars

This fun, festive treat brings all the magic of Halloween into one soft sugar cookie bar crowned with a fluffy swirl of vanilla cream cheese frosting. Every bite is a celebration thanks to the jimmie-style sprinkles and vibrant seasonal colors.

Baking with my kids always turns into a sprinkle explosion across our kitchen usually the purple and orange sprinkles end up on the counter as much as on the bars and it is always worth the cleanup for their giggles and pride when we serve these together

Storage Tips

Keep sugar cookie bars in an airtight container in the fridge for up to three days. Place a sheet of wax or parchment paper between layers so the frosting stays intact. Before serving allow the bars to come to room temperature for the creamiest frosting and softest bite.

Ingredient Substitutions

If you are out of cream cheese you can make a quick vanilla buttercream with just butter powdered sugar vanilla and a splash of milk. Dairy free butter and plant based milk work fine for the cookie base but the bars may be slightly less rich. Allergic to eggs Replace with a flax egg one tablespoon ground flax plus two and a half tablespoons water and increase the baking powder by a small pinch.
