Although I’d never turn my back on a traditional cookie, I do love how easy bar cookies come together. Similar to Snickerdoodle Bars, these require no rolling or shaping.
Mix the (traditional or gluten-free) batter together in one bowl, dump it in a pan, and bake. An emergency dessert can be ready in no time for all occasions!

Make this recipe For All Holidays!
- 4th of July or Memorial Day – Use red, white, and blue sprinkles and leave buttercream white.
- Christmas – Use holiday sprinkles or top with crushed candy canes. Leave buttercream white or tint green.

- Easter – Tint frosting a pastel color and top with Easter themed sprinkles, jelly beans, or mini Cadbury eggs
Yes. For gluten free sugar cookie bars simply replace the flour with an all purpose gluten-free flour. It may need 2-3 minutes additional baking time. For best results, use Cup 4 Cup gluten free flour.
When making a gluten free recipe, be sure to read the ingredient labels carefully on the sprinkles. Some brands do contain gluten additives.
Some home bakers prefer the taste of sugar cookie bars with cream cheese frosting. Halve the cream cheese frosting recipe from red velvet cake recipe or, for a different flavor, substitute chocolate buttercream frosting.
Yes and you have two options. For a thicker, soft bar leave the ingredient amounts as is and bake for 25 minutes.
Alternatively, halve the bar and frosting ingredients and bake for 5-10 minutes less.
Be sure to use sprinkles or jimmies rather than nonpareils (tiny ball sprinkles). Nonpareils’ color will bleed into the dough, so instead of funfetti speckles, they will be one unsightly color.
Cover any leftovers securely with plastic wrap and leave at room temperature up to 3 days. They may also be frozen, covered securely, up to 3 months. Alternatively, wrap individually and enjoy as needed!

Sugar Cookie Bars
Sugar Cookie Bars
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 1 egg + 1 egg yolk, room temperature
- 2 teaspoons vanilla extract
- ¼ teaspoon salt
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- 1 ½ teaspoons cornstarch
- 1 ½ cups all-purpose flour or gluten free all-purpose flour, (My preferred brand is Cup 4 Cup gluten free flour)
- ½ cup rainbow sprinkles (NOT nonpareils)
- ¾ cup unsalted butter, softened
- 2 cups powdered sugar
- 6 tablespoons heavy cream
- 1 teaspoon vanilla extract
- ⅛ teaspoon salt
- food coloring, optional
- extra sprinkles for decorating top
- Preheat the oven to 350ºF. Spray a 9X13 baking pan with cooking spray and set aside.
- In a large bowl cream together the butter and sugar together until very pale, light, and fluffy, about 3 minutes. Beat in egg, yolk, and vanilla until well mixed.
- To the bowl add the salt, baking powder, baking soda, and cornstarch. Mix well. Gradually add in the flour and beat on low speed until just combined. The dough will be very thick. Stir in sprinkles or mix on low speed.
- Spread the cookie mixture in the prepared baking pan. Bake for 23-25 minutes (about 2-3 minutes longer if using gluten free flour) until a toothpick inserted in middle comes clean. The bars will be lightly browned. Allow the bars to cool completely on wire rack before frosting.
- In a large bowl beat the butter until light and creamy. Add the powder sugar, heavy cream, vanilla, and pinch of salt. Gradually mix on low speed until well mixed.
- Increase mixer to high and beat until very light and fluffy, about 5-7 minutes. TIP: Beating for a long time is what makes this frosting extremely fluffy. Mix in food coloring, if using.
