How to Make Frosted Sugar Cookie Bars
-
Preheat: Start by preheating your oven to 350°F (177°C). Line an 8-inch or 9-inch square pan with aluminum foil, leaving overhang for easy removal later.
-
Cream Butter: In a large bowl, cream the softened butter using a mixer on medium speed for about 1 minute. Add in the granulated sugar and beat until fluffy and light in color, about 2-3 minutes.
-
Mix Wet Ingredients: Next, beat in 1 large egg, 1 egg yolk, and 2 teaspoons of pure vanilla extract. Don’t forget to scrape down the sides of the bowl to incorporate all the ingredients!
-
Combine Dry Ingredients: In a separate medium bowl, whisk together 1 and 1/2 cups all-purpose flour, 1/4 teaspoon salt, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1 and 1/2 teaspoons cornstarch.
-
Blend Mixtures: With the mixer on low speed, gradually add the dry ingredients to the wet mixture in three parts. The dough will be thick but ensure it’s mixed well.
-
Add Sprinkles: Gently fold in 1/2 cup of rainbow sprinkles using a silicone spatula or mix slowly on low speed until incorporated.
-
Press Dough: Press the cookie dough evenly into the lined baking pan, making sure it’s smooth and even across the top.
-
Bake: Bake in the preheated oven for 25-26 minutes or until the top is lightly golden. Allow to cool completely on a wire rack before frosting—don’t worry if the center sinks slightly!
-
Make Frosting: For the frosting, beat 3/4 cup softened butter on medium speed until creamy, about 2 minutes. Add in 2 and 1/4 cups confectioners’ sugar, 3 tablespoons heavy cream, and 1 teaspoon vanilla extract.
-
Frost: Increase the mixer speed to high and beat the frosting for 3 minutes, adjusting with more sugar or cream as needed. Once cooled, remove the cookie bars using the foil overhang, frost them, and decorate with extra sprinkles if desired.

Expert Tips for Frosted Sugar Cookie Bars
-
Room Temperature Ingredients: Ensure your butter and eggs are at room temperature. This helps create a creamy mixture and better texture in the bars.
-
Don’t Overmix: When combining dry and wet ingredients, mix just until incorporated. Overmixing can lead to tough cookie bars instead of the soft, chewy texture you’re aiming for.
-
Check for Doneness: Keep an eye on your bars while baking; they’re done when the top is lightly golden. Overbaking can result in dry cookies.
-
Cooling Is Key: Allow the bars to cool completely before frosting. This prevents the frosting from melting and ensures a beautiful finish.
-
Adjusting Frosting Consistency: If your frosting is too thick, add a tiny bit more heavy cream until you reach your desired consistency. A pinch of salt can balance the sweetness perfectly!
-
Fun Decorations: Don’t hesitate to get creative with your Frosted Sugar Cookie Bars. Experiment with different sprinkles or colored frosting to match the occasion!

Frosted Sugar Cookie Bars Recipe FAQs
What type of butter should I use?
I recommend using unsalted butter, as it allows you to control the saltiness of your bars. Make sure the butter is softened to room temperature for the best creaming results, which helps create a light and fluffy texture.
How should I store my Frosted Sugar Cookie Bars?
Store your frosted bars in the refrigerator for up to a week, keeping them in an airtight container to prevent drying out. If they’re unfrosted, you can keep them at room temperature in an airtight container for up to 3 days.
Can I freeze Frosted Sugar Cookie Bars?
Absolutely! To freeze, wrap the bars tightly in plastic wrap, then place them in a freezer-safe container. They’ll stay fresh for up to 3 months. Thaw at room temperature before serving, and they’ll be just as delightful as the day you made them!
What if my cookie bars turn out too crumbly?
If your bars are crumbly, it could be due to using too much flour or overbaking. Make sure to measure your flour correctly by spooning it into the measuring cup and leveling it off. Also, be mindful not to bake them past the lightly golden stage to keep that soft texture.
Are Frosted Sugar Cookie Bars safe for people with allergies?
These bars contain gluten, dairy, and eggs, which are common allergens. For a gluten-free version, you can try using a gluten-free flour blend. If you’re concerned about dairy or eggs, numerous alternatives can be made by substituting with vegan options. Always check labels carefully to ensure safety for anyone with dietary restrictions!
