I’ve mentioned this before, but I’m often too lazy to make cut-out sugar cookies. Waiting for the dough to chill, rolling them out, then making multiple batches just sounds like a lot of work. I often opt for Amish sugar cookies, soft & chewy M&M sugar cookies, or sugar cookie cups.
But, when you turn sugar cookie dough into easy sugar cookie bars, then you spark my interest.
This recipe takes everything you love about traditional sugar cookies, but puts it into super simple, from scratch, bar form.
For the sugar cookie bars
- Butter – Unsalted butter, softened to room temperature so it’s easy to work with.
- Sugar – Granulated white sugar.
- Eggs – Two large eggs, at room temperature.
- Vanilla Extract – Try to use real vanilla extract, even though it’s expensive right now. I buy it in bulk at Sam’s Club or Costco. If you want to switch up the flavor of these bars, you can also opt for almond or lemon extract instead.
- Flour – All purpose white flour.
- Salt – For balance.
- Baking Powder – For rise.
For the frosting
- Butter – I personally like to use salted butter in frosting to balance the sweetness, but most people opt for unsalted.
- Powdered Sugar – Also referred to as confectioners’ sugar.
- Vanilla Extract – Again, reach for the pure vanilla extract, not imitation, for the best flavor.
- Salt – Pinch of salt. I add another pinch even when I use salted butter, but I don’t like overly sweet things so this is a personal preference.
- Milk – You just need a bit, use what you have on hand. We always have 2%.
TOOLS FOUND ON AMAZON TO HELP YOU:

SPRINKLES – There are so many fun combos right on Amazon now.
HOW TO MAKE SUGAR COOKIE BARS
STEP ONE: To a large mixing bowl, cream together the butter and sugar into light & fluffy. One at a time, add the eggs and beat in between until incorporated. Mix in the vanilla extract.
STEP TWO: To a small mixing bowl, whisk together the flour, salt, and baking powder.
STEP THREE: Pour the flour mixture into the wet ingredients and fold with a spatula just until combined. Don’t overmix.
STEP FOUR: Press the dough into a greased 9 x 13 pan and bake for 20 minutes at 350 degrees for 20 minutes or until the edges are just golden. You don’t want them to brown. Remove from oven and let cool.
STEP FIVE: While the bars are cooling, make the frosting by beating the softened butter in a large mixing bowl until creamy. Pour in the powdered sugar and beat. It will look crumbly. Pour in the vanilla, pinch of salt, and 1 Tablespoon of milk. Mix. If it’s soft & spreadable, you’re done. If it looks dry, drizzle in more milk until it’s the consistency you’re after.
STEP SIX: Frost the cooled bars right in the pan with an offset spatula or knife. Top with sprinkles then slice into bars.
EASY TO CUSTOMIZE
One of the best parts about this recipe is how easily customizable the bars are.
Making them for Halloween? Orange food coloring & black & orange sprinkles (& eyeballs!).
Whatever the occasion, these bars are down to help you celebrate.
HOW MANY BARS DOES THIS MAKE?
This sugar cookie bars recipes makes a 9 x 13 pan. How generous you cut them is up to you. At the very least, it should make 12 bars. If you cut them smaller, you can get 15-20 and still have very nice sized portions.
HOW TO STORE THEM
I store these bars covered, at room temperature, for 3-4 days, but they never last that long.
CAN YOU FREEZE THEM?
Yep, you can freeze them. They even freeze well frosted. Just wrap them in plastic wrap, drop them into a freezer bag, and freeze for up to a couple months. To thaw, set them on the counter at room temperature when you’re ready to eat them.
