Frosted Sugar Cookie Bars: From Prep to Plate

Now, let’s dive into the steps to create these delightful Frosted Sugar Cookie Bars!
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This is essential for baking the bars evenly.
Step 2: Prepare Your Baking Pan
Grease your 9×13 inch baking pan with a bit of butter or line it with parchment paper for easy removal.
Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
Step 4: Cream the Butter and Sugar
In a large mixing bowl, beat the unsalted butter and granulated sugar together using an electric mixer until the mixture is light and fluffy.
Step 5: Add Cream Cheese
Add the cream cheese to the butter-sugar mixture and mix until well combined and smooth.
Step 6: Incorporate Egg and Vanilla
Add the egg and vanilla extract to the mixture. Beat until fully incorporated.
Step 7: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients, mixing just until combined. Be careful not to overmix!
Step 8: Bake the Bars
Spread the cookie dough evenly into the prepared baking pan. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Step 9: Cool the Bars
Once baked, remove the pan from the oven and let the bars cool completely in the pan on a wire rack.
Step 10: Make the Frosting
In a separate bowl, beat together the softened unsalted butter, powdered sugar, and vanilla extract until smooth and fluffy.
Step 11: Frost the Cookie Bars
Once the bars are completely cooled, spread the frosting evenly over the top of the bars using a spatula.
Step 12: Add a Splash of Color
Top the frosted bars with rainbow sprinkles for that extra festive touch.
Step 13: Cut and Serve
Cut the bars into squares or rectangles and serve. Enjoy the compliments as they disappear!
Dietary Customizations

If you want to customize your Frosted Sugar Cookie Bars, consider these options:
- Gluten-Free: Substitute all-purpose flour with a gluten-free flour blend.
- Dairy-Free: Use vegan butter and a dairy-free cream cheese alternative.
- Reduced Sugar: You can reduce the granulated sugar by 25% without significantly affecting the texture.
- Flavor Variations: Add almond extract instead of vanilla for a different flavor profile.
Mistakes That Ruin Frosted Sugar Cookie Bars
To ensure your Frosted Sugar Cookie Bars turn out perfectly, avoid these common pitfalls:
- Overmixing the Dough: This can lead to tough bars instead of soft ones.
- Not Measuring Ingredients Accurately: Baking is a science; precise measurements are crucial for the right texture.
- Baking at the Wrong Temperature: Make sure your oven is preheated properly for even baking.
- Skipping the Cooling Step: Frosting warm bars will result in a melty mess instead of a beautiful finish.
Store, Freeze & Reheat
To keep your Frosted Sugar Cookie Bars fresh and delicious:
- Store: Keep the bars in an airtight container at room temperature for up to 3 days.
- Freeze: For longer storage, freeze the bars before frosting. Wrap them tightly in plastic wrap and store in a freezer-safe container for up to 3 months.
- Reheat: If you prefer them warm, simply microwave a bar for about 10-15 seconds.
Common Questions
Can I use margarine instead of butter?
While margarine can be used, it may alter the flavor and texture of your Frosted Sugar Cookie Bars. Unsalted butter is recommended for the best results.
How do I know when the cookie bars are done baking?
The bars are done when the edges are lightly golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
Can I make these bars ahead of time?
Absolutely! You can make the bars a day in advance, and they will stay fresh. Just store them in an airtight container until you’re ready to serve.
Can I use different toppings besides sprinkles?
Yes! Feel free to top the frosting with chocolate chips, crushed nuts, or even fresh fruit for a unique twist.
