Ingredient Notes

- Granulated Sugar – This adds sweetness to the cookie bars.
- Brown Sugar – This adds moisture, chewiness, and a hint of caramel flavor to the bars.
- Eggs – Eggs help bind the ingredients together and add richness to the cookie bars.
- Vanilla Extract – Pure vanilla extract enhances the overall flavor of both the bars and the frosting.
- All-Purpose Flour – This provides the structure for the cookie bars. Make sure to measure the flour correctly for the best texture.
- Baking Soda – Using baking soda will help the bars rise slightly and have a tender texture.
- Salt – Salt balances the sweetness and enhances the flavors.
- Powdered Sugar – Powdered sugar is the key ingredient in the frosting, giving it a smooth and creamy texture.
- Milk – Milk helps thin out the frosting to your desired consistency and adds moisture.
- Sprinkles – Red, white, and blue sprinkles add a festive touch.
Add-ins and Substitutions
- Add Chocolate Chips: Stir in 1 cup of semi-sweet, milk chocolate, or white chocolate chips into the cookie dough for extra richness.
- Use Different Sprinkles: Swap out the patriotic sprinkles for any color or theme that fits your celebration.
- Add Flavored Extracts: Experiment with other extracts in the frosting, such as almond or lemon.

How to Make Patriotic Cookie Bars
Get ready for the easiest and most delicious cookie bars you’ve ever made. Follow these simple steps for perfect Patriotic Cookie Bars.
- Prep the oven and pan: Preheat your oven to 350°F and lightly grease a 9×13 inch baking pan.
- Combine wet ingredients: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract.
- Mix the dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.
- Combine wet and dry: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
- Press the batter: Press the cookie dough evenly into the prepared baking pan.
- Bake: Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
- Cool the bars: Let the cookie bars cool completely in the pan before frosting. This is important to ensure the frosting doesn’t melt.
- Make frosting: In a medium bowl, cream together the softened butter and powdered sugar until smooth. Beat in the vanilla extract and milk until the frosting reaches your desired consistency. Add more milk, if needed, to thin the frosting.
- Frost and decorate: Spread the frosting evenly over the cooled cookie bars. Top with sprinkles.
- Chill and serve: Chill the frosted bars in the refrigerator for at least 30 minutes to allow the frosting to set. Cut into squares and serve.
- Pro Tip: Make sure your butter is softened but not melted. This helps to achieve the perfect texture in both the cookie bars and the frosting.
Recipe Tips
- Don’t overbake. Keep a close eye on the bars while baking and remove them from the oven when the edges are golden. Overbaked bars will be dry.
- Let the bars cool completely. This prevents the frosting from melting and sliding off.
- Use room temperature ingredients. This allows the ingredients to combine more easily, resulting in a smooth batter and creamy frosting.
- Chill the frosted bars. This firms up the frosting and makes them easier to cut and serve.
- Store leftovers. If you have any leftover cookie bars, store them in an airtight container at room temperature for up to 3 days.
FAQs
- Can I make these cookie bars ahead of time? Yes, you can make the cookie bars and the frosting one day in advance. Store the frosted bars in the refrigerator.
- Can I freeze these cookie bars? Yes, you can freeze the unfrosted cookie bars. Wrap them tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 months. Thaw completely before frosting.
- How do I store the cookie bars? Store the frosted cookie bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
- What if I don’t have brown sugar? If you don’t have brown sugar, you can substitute with the same amount of granulated sugar, but the bars might not be as chewy.
Serving Suggestions
- With Coffee or Tea: These Patriotic Cookie Bars pair perfectly with a hot cup of coffee or tea.
- With Ice Cream: Serve a scoop of vanilla ice cream alongside the cookie bars for an extra treat.

Make This Recipe in Advance
The cookie bars can be made 1-2 days in advance and stored, unfrosted, at room temperature, but it’s best to frost them just before serving. The frosting can be made a day ahead and stored in the refrigerator until needed. For longer storage, you can freeze the baked, unfrosted cookie bars for up to two months. Thaw them completely before frosting and serving. Enjoy!
