How to Make Red White & Blue Sugar Cookie Bars
STEP 1. Preheat the oven. Set your oven to 375°F.
STEP 2. Prepare the baking pan. Grease or line a 9×13-inch baking pan with parchment paper.
STEP 3. Cream the butter and sugars. Beat the salted butter, granulated sugar, and brown sugar together until fluffy and light.
STEP 4. Add the eggs. Mix in the large egg and the egg yolks until fully incorporated.
STEP 5. Stir in flavorings. Add the vanilla extract and optional almond extract, mixing well.
STEP 6. Combine dry ingredients. In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
STEP 7. Mix the batter. Gradually stir the dry mixture into the wet ingredients until just combined.
STEP 8. Transfer to the pan. Pour the batter into the prepared baking pan and spread evenly.
STEP 9. Bake the bars. Place in the oven and bake for about 15-20 minutes, until the edges are light golden brown.
STEP 10. Cool in the pan. Allow the bars to cool completely in the pan before frosting.
STEP 11. Prepare the frosting. Beat the additional salted butter in a bowl until fluffy, then gradually add the powdered sugar, vanilla extract, and heavy cream until a spreadable consistency is reached.
STEP 12. Frost the cooled bars. Spread the frosting evenly over the cooled cookie bars.
STEP 13. Decorate. Top the frosted bars with red, white, and blue sprinkles before serving.

Pro Tips
To achieve the perfect texture, ensure your butter is soft but not melted. Creaming the butter and sugars properly will incorporate air, leading to a more tender bar. For a rich flavor, don’t skip the vanilla; it’s essential for enhancing the taste of the bars. Make sure to cool the bars completely before frosting; otherwise, the frosting may melt. When adding sprinkles, do this right after frosting to ensure they stick well. If you want to cut the bars into clean squares, use a sharp knife and run it under hot water, wiping it dry before cutting each time for a perfect finish.
Common Mistakes to Avoid
A common mistake is overmixing the batter after adding the flour, which can lead to tough bars. Ensure you don’t skip weighing your flour or just using the scoop method, as this may result in too much flour in your mix. Another pitfall is baking for too long—watch for that light golden brown around the edges to avoid dry bars. Be cautious with the frosting; make sure the bars are fully cooled before frosting to maintain a beautiful appearance. Always measure your ingredients accurately, as baking is a precise science, especially when balancing flavors and textures.
Variations
• Add chopped nuts for added crunch.
• Incorporate chocolate chips for a decadent twist.
• Use different sprinkle colors for various holidays.
• Substitute almond extract with lemon extract for a citrus flavor.
• Experiment with cream cheese frosting for a tangy sweetness.
Serving Ideas
These cookie bars can be served at room temperature or chilled for a refreshing treat, especially on hot days. They make great additions to dessert tables at holiday parties, backyard barbeques, or picnics. Pair them with a scoop of vanilla ice cream for an indulgent dessert. They can also be enjoyed with a cup of coffee or tea for a sweet afternoon pick-me-up. For a colorful presentation, slice into shapes using cookie cutters and serve on platters for a festive display.
Meal Prep & Storage
Store your sugar cookie bars in an airtight container to maintain their freshness. They can be kept at room temperature for up to three days. For longer storage, refrigerate them, which will keep them fresh for about a week. If you want to enjoy them later, these bars freeze well. Wrap them tightly in plastic wrap or aluminum foil, or place them in a freezer-safe bag. They can be frozen for up to three months. For serving, thaw the bars in the refrigerator or at room temperature.

FAQs
Can I make these cookie bars ahead of time?
Absolutely! These bars are perfect for making in advance. You can bake and frost them the day before your event.
What if I don’t have heavy cream for the frosting?
If you don’t have heavy cream, you can substitute with milk or half-and-half, although the frosting will be slightly less rich.
Can I use unsalted butter instead?
Yes, unsalted butter can be used, but if you do, consider adding a pinch of salt to balance the flavors in both the cookie bars and frosting.
How do I ensure my cookie bars are chewy?
Make sure you accurately measure your flour and avoid overmixing once you’ve added it to the wet ingredients; this helps create those delicious chewy bars.
What can I use instead of egg for a vegan version?
You can substitute with flaxseed meal mixed with water or a commercial egg replacer. This will help to bind the ingredients together, similar to how eggs work.
