Description

Easy Snickerdoodle Cookie Bars taste like the classic cookie but are so much simpler to make. Soft, chewy, and absolutely irresistible – everything you love about snickerdoodles in bar form!


Ingredients

For the Dough/Base:

  • ¾ cup butter, melted (I use whatever’s cheapest at the store)
  • ¾ cup brown sugar, packed tight
  • 1 cup white sugar
  • 2 eggs (leave them on the counter while you gather everything else)
  • 2 teaspoons vanilla – the real stuff, not imitation
  • 2 cups flour
  • 1 teaspoon baking powder
  • 1 teaspoon cream of tartar (this is key!)
  • ½ teaspoon salt

For the Topping:

  • ¼ cup white sugar
  • 2 teaspoons cinnamon (I buy the big container from Costco)


Instructions

Preheat and prep

Turn your oven to 350°F. Grease your pan really well – I learned this after peeling bars off the bottom piece by piece. Not fun.

Make the base

Melt your butter in the microwave (30-second bursts so it doesn’t explode). Mix it with both sugars until it looks smooth. Crack in your eggs one at a time, then pour in the vanilla. Everything should look creamy and smell amazing.

Add the dry stuff

Dump in the flour, baking powder, cream of tartar, and salt. Stir just until you can’t see white flour anymore. Don’t go crazy mixing or you’ll get tough bars that nobody wants to eat.

Spread and top

Plop this thick dough into your pan and smoosh it flat with your hands. Mix that quarter cup of sugar with the cinnamon in a small bowl, then sprinkle it everywhere on top.

Bake

Stick it in the oven for about 22 minutes. They’re done when the top looks golden and doesn’t jiggle when you shake the pan.

Cool down

This is the hardest part – wait 30 minutes before cutting. I know they smell incredible, but trust me on this one. Hot bars = crumbly mess.

Notes

Cold eggs make lumpy batter. I forget to take them out every single time, so I just plunk them in a bowl of warm tap water while I get everything else ready. Five minutes and they’re perfect.

Don’t pack your flour down like you’re building a sandcastle. I used to really smush it in there and wondered why my bars were dense as rocks. Just scoop it in gently and level the top.
