  • Flour – I used all-purpose flour, also known as plain flour. Make sure you spoon and level if using cup measurements. As usually, measuring with kitchen scales is the best way for recipe success.
  • Bread flour – this is a high gluten flour that helps give these bars a nice chewy texture.
  • Salt – I used fine salt.
  • Baking powder – helps the cookies rise.
  • Butter – Melt your butter first and let it cool down to room temperature without setting.
  • Granulated sugar -caster sugar will also work.
  • Eggs – I used a whole large egg and an egg yolk to help give these cookies an even chewier texture.
  • Rainbow sprinkles – I used rainbow jimmies. You can use whichever colored sprinkles you like.

Tips and Tricks For Recipe Success!

  • Make sure you line your baking tin with baking paper for an easy lift out cookie experience!
  • No need to chill this dough, it goes straight in the oven. Bake on the middle rack.
  • Spread the dough out so it’s nice and even before baking.
  • Underbaking gives you chewy, fudgy cookie bars.
  • Cool down before frosting to avoid a melting disaster like I did when I was a kid once.
  • Add 1/2 tsp of almond extract for extra flavor or 1/4 tsp of peppermint extract for something festive.
  • Use a large sharp knife to slice cookie bars. I like to carefully wipe my knife with a paper towel before each slice for extra sharp and clean slices.
  • Make sure you chill your bars before slicing.

Frequently Asked Questions about Frosted Cookie Bars

How do I store the cookie bars?

Store in an airtight container for up to 3 days. They get chewier the next day!

Can I make the frosting ahead of time?

Yep! Make it up to three days ahead of time. Store in the fridge, covered. Thaw completely at room temperature before whipping up again.

What type of sprinkles should I use?

I used rainbow sprinkles. We don’t have good sprinkles in Australia, we just don’t so I buy mine on Amazon. They’re the Hoosier farm brand ones. They’re not quite as good as the American ones, but it’s as close as I’ve ever found. You don’t want to use 100’s and 1000’s. they melt in the oven.

Can I use a different sized pan?

I tested this in a 9×9 inch baking tin and they came out too thin. You can use a loaf tin and cut them into thinner bars. They will be a little taller.

Can I freeze them?

Yes! Freeze in an airtight container for 2-3 weeks.

Can I double the recipe?

Yep! Bake in a 9×13-inch cake tin and double the frosting amount.
