Mummy Sugar Cookie Bars

The perfect little Halloween treat!


These Mummy Sugar Cookie Bars come together frighteningly easy! With a soft cookie base covered with a sweet creamy frosting, these make the perfect treat for your monsters leading up to the 31st!

These bars actually came together by mistake. I was planning to make Halloween sugar cookies with the twins, but realized all my cookie sheets were still packed away. Luckily my baking dishes were out and ready to use!

I’ve included a basic frosting recipe, but you can definitely use any type of frosting you like! Have fun with the decorating, always the most fun part!

Sugar cookie dough

  • 1/2 cup butter, softened at room temperature
  • 1 cup white sugar
  • 1 egg
  • 1 1/2 tsp vanilla extract
  • 2 1/4 cups flour
  • 1.5 tsp baking powder
  • 1/2 tsp salt

Orange icing

  • 1/2 cup butter, softened at room temperature
  • 2 cups powdered sugar
  • 1 tsp vanilla extract
  • 1/3 – 3/4 cup milk
  • yellow & red food colouring

1. Preheat oven to 350 degrees. Line a 11×8 baking dish with parchment paper. If you use a larger dish, the bars will be thinner but will still work!

2. In a large bowl or a stand mixer with the paddle attachment, beat the butter and sugar until creamy and light – around 2 minutes.

3. Add the egg and vanilla extract, continue beating.

4. Finally add in the flour, baking powder and salt – mix until combined.

5. Press the cookie dough into the baking dish, trying to achieve an even spread.

6. Bake for 20-25 minutes until the edges are just starting to turn a light golden brown. Cool completely before adding the icing and spooky treats!

7. While your bars are baking, whip up your icing. Beat the softened butter until creamy and smooth. Add in the vanilla and continue beating. Add in the powdered sugar gradually. At this point you’re going to slowly add in the milk. I do about 2 tbsp at a time until I reach a creamy and spreadable consistency. Too runny? Add in some extra powdered sugar. Too dry? Add in a little milk.

8. Okay this is the fun part – add in your food coloring. Add one drop of red and about 10 drops of yellow. Continue mixing.

9. Once your bars are cool, add your icing. I used a piping bag to create the mummy stripes! Decorate with your facourite spooky treats. Cut and serve!
