Ingredients and substitutions for Hundreds and Thousands Cookie Bars
- Butter: Unsalted butter is used for the cookie, but if all you have on hand is salted, that works as a fine substitute, just leave out any salt suggested in the recipe.
- Sugar: Confectioners or icing sugar dissolves into the buttercream and the superfine or caster sugar adds to the sugar portion of our cookies creating a nice balance without making them overly sweet.
- Eggs: The egg binds and adds structure to our cookies resulting in that soft interior that compliments the sugar and butter.
- Flour: Plain or all purpose flour is best for a nice light cookie crumb.
- Baking powder: This helps our cookies rise so they are not stodgy.
- Raspberry Jam: The color and flavor of the buttercream is thanks to jam which means we don't need any food coloring.
- Sprinkles: Traditional hundreds and thousands sprinkles work best here, but you do you and add whatever sprinkles you wish!

Variations
You can definitely change up the dish by changing the following:
Chocolate: You could use cocoa powder in the cookie base (omiting a portion of flour so as not to create dry cookies) or add melted chocolate or cocoa powder to the buttercream.
Fruity cookie base: Adding a few tablespoons of freeze dried fruit powder from blueberries to raspberries for a twist on the vanilla cookie base.
Equipment needed to make this
Greaseproof paper: Lining your baking tray will make getting the soft cookies off easy.
Hand or stand mixer: To whip the cookie dough and that buttercream, this is best done with a mixer.
Mixing bowl: You’ll need two medium mixing bowls to mix the cookie dough and buttercream.
Offset spatula: A small offset spatula will help you smooth out the buttercream nice and evenly. A butter knife or back of a tablespoon will also do the trick.
Square tin: A 18×18 cm or 7×7 inch square baking tin works well here, though a rectangle tin would also work well.
FAQ's for the best Hundreds and Thousands Cookie Bars
Can I make cookie bars ahead?
Yes!! They are great up to two days after baking with the buttercream frosting, before it's better to put them in the fridge, though that might dry the cookies out a little.
