Hundreds and Thousands Cookie Bars includes a vanilla butter cookie base smeared with raspberry buttercream and topped with hundreds and thousands sprinkles for a twist on a Kiwi classic!
Preheat oven to 180C/350F and line a square baking tin with greaseproof paper.
Place the butter and sugar into a bowl and beat on medium until pale and fluffy, approximately 3 minutes.
Add in the egg and vanilla extract and combine until smooth, approximately 1 minute.
Add your flour and baking powder and beat on the lowest setting until the flour has just been combined and no dry portions remain in your bowl.
Pour the mixture into your tin and press firmly with your hand and then even out with an offset spatula into your baking tin.
Place in the oven and bake for 20 minutes or until ever so slightly golden.
Remove and allow to cool completely.
Raspberry buttercream
To make the buttercream filling, place the butter and sugar into a bowl and beat on medium with an electric mixer until pale and fluffy, approximately 4 minutes.
Add in the raspberry jam and salt and stir until fully combined.
Remove the bars from the tin and mark out the edges where you will cut your cookies.
Spoon the buttercream on top of the cookie and smear to the very edges, swooshing a little.
Sprinkle over the hundreds and thousands sprinkle.
Slice and serve.
Enjoy!

Notes
Raspberry Jam: The color and flavor of the buttercream is thanks to jam which means we don't need any food coloring.
Square tin: A 18×18 cm or 7×7 inch square baking tin works well here, though a rectangle tin would also work well.
Customizing the recipe: You can customize the flavor of the sugar cookie base by adding extracts or zest to the cookie dough, or even mix in different types of sprinkles for a unique twist.
