Ingredients You’ll Need
Gathering the ingredients for this Soft Sugar Cookie Bars with Buttercream Frosting Recipe is delightfully simple. Each component plays a crucial role in delivering that perfect balance of softness, sweetness, and buttery richness.
- Unsalted butter: The foundation for both the cookie base and frosting, offering creaminess and richness.
- Granulated sugar: Adds sweetness and helps achieve a tender texture in the cookie.
- Large egg: Binds ingredients together while keeping the cookie moist and soft.
- Vanilla bean paste or vanilla extract: Infuses a deep, aromatic flavor that complements the sugar cookie perfectly.
- All-purpose flour: The structure-building ingredient, giving the bars their shape without toughness.
- Kosher salt: Enhances flavor, balancing the sweetness beautifully.
- Baking soda: Lightens the cookie bars and helps with their gentle rise.
- Powdered sugar: Essential for silky-smooth buttercream frosting.
- Cream or milk: Adjusts the buttercream’s texture to be soft and spreadable.

- Sprinkles (optional): Adds a pop of color and whimsy to your finished bars.
How to Make Soft Sugar Cookie Bars with Buttercream Frosting Recipe
Step 1: Prepare Your Pan and Preheat the Oven
Start by preheating your oven to 350°F (180°C). Grease a 9×13 inch pan and line it with parchment paper, leaving a little overhang on the sides. This handy trick will let you lift your cookie bars out cleanly once they’re cooled, ensuring perfect edges and easy cutting.
Step 2: Cream the Butter and Sugar
In a mixer, whip room temperature butter and granulated sugar until the mixture is light and fluffy. This step is key to creating that soft, tender crumb in your cookie bars. Then, beat in the egg and vanilla to infuse the dough with flavor and moisture.
Step 3: Combine Dry Ingredients and Mix into Dough
Sift together the flour, kosher salt, and baking soda to keep the texture light and free of lumps. Add these dry ingredients to the butter mixture and mix only until combined — overmixing can lead to tougher bars, so be gentle here.
Step 4: Spread the Cookie Dough
Transfer your cookie dough to the prepared pan and evenly spread it out with an offset spatula. If you want a little sparkle, sprinkle granulated sugar over the top before baking to add a subtle crunchy texture and shine.
Step 5: Bake and Cool
Bake your cookie bars for 20 to 25 minutes until they turn lightly golden brown on top and are set in the center. You’ll notice the edges may crinkle, and the bars will deflate slightly once out of the oven — that’s exactly how you want them! Let them cool completely in the pan on a wire rack.
Step 6: Make the Buttercream Frosting
While the bars cool, whip together butter, vanilla, and salt until pale and creamy. Gradually sift in powdered sugar and mix until smooth. Add a splash of cream or milk to achieve the perfect, spreadable consistency. This stage is your chance to add gel food coloring if you want a fun twist.
Step 7: Frost and Finish
Lift the cooled bars out of the pan with the parchment paper and place them on a serving platter. Spread the luscious buttercream evenly over the top with an offset spatula or the back of a spoon. Add sprinkles if you like for a playful touch.
Step 8: Chill and Cut
Pop the frosted bars into the fridge briefly — just enough for the frosting to set, which makes cutting neat, clean squares a breeze. Use a sharp knife wiped between cuts to keep those edges tidy.
How to Serve Soft Sugar Cookie Bars with Buttercream Frosting Recipe
Garnishes
Sprinkles are the classic choice for these bars, adding joyful bursts of color and whimsy. Alternatively, try edible glitter or a light dusting of powdered sugar for an elegant touch. Fresh berries on the side can also add a refreshing contrast to the rich sweetness.
Side Dishes
This recipe shines on its own, but pairing your sugar cookie bars with a simple cup of tea or a chilled glass of milk can elevate your dessert experience. For a crowd, a scoop of vanilla ice cream alongside each serving brings a lovely temperature and texture contrast.
Creative Ways to Present
Cut the bars into bite-sized squares for a party platter, layering them with parchment for a beautiful homemade gift box. Another fun idea is to use cookie cutters on the bars after frosting to create fun shapes for birthdays or holidays. You can even swirl two colors of buttercream on top for a marbled effect that’s eye-catching and delicious.
Make Ahead and Storage
Storing Leftovers
Once frosted, store your Soft Sugar Cookie Bars with Buttercream Frosting Recipe in an airtight container at room temperature or in the fridge for up to five days. Keeping them covered prevents the frosting from drying out and the bars from becoming stale, preserving their fresh-baked softness.
Freezing
These cookie bars freeze well before frosting. Wrap the uncut bars tightly in plastic wrap and place in a freezer-safe container. When ready to enjoy, thaw overnight and then frost fresh. While you can freeze frosted bars, the buttercream texture may change after thawing, so frosting after is best.
Reheating
If you prefer your cookie bars slightly warm, remove frosting if possible and warm bars briefly in a low oven or microwave, then reapply frosting if you like. Warming brings back softness and enhances the buttery aroma but go gently since buttercream melts quickly.
FAQs
Can I use salted butter for this recipe?
While you can substitute salted butter, it’s best to use unsalted to control the saltiness precisely. Using unsalted butter and adding kosher salt as directed ensures the perfect balance of flavor in your Soft Sugar Cookie Bars with Buttercream Frosting Recipe.
Can I make this recipe gluten-free?
Yes! Swap the all-purpose flour for a gluten-free blend that can be used cup-for-cup. Just make sure it contains xanthan gum or a similar binder to keep the texture soft and cohesive.
How long does the frosting take to set?
The frosting usually firms up in about 20 to 30 minutes in the fridge. This chilling step makes it easier to cut the bars cleanly without smudging the frosting.
Can I use this recipe for individual cookies?
Absolutely! The dough works well for cookies, though baking times will be shorter—around 10 to 12 minutes depending on size. The frosting is perfect for spreading or piping as well.
What if I don’t have vanilla bean paste?
Vanilla extract is a great substitute and will still give your bars that lovely vanilla flavor. Vanilla bean paste offers flecks and a richer taste but isn’t essential.
Final Thoughts
There’s something truly special about the Soft Sugar Cookie Bars with Buttercream Frosting Recipe that feels both nostalgic and exciting to make. Whether it’s for a celebration, a gift, or just a cozy treat at home, these bars deliver on texture, flavor, and that festive sweetness we all crave.

For the Sugar Cookie Bars
- 225g unsalted butter, at room temperature
- 300g granulated sugar
- 1 large egg (50g, not including the shell), at room temperature

- ½ tsp salt
- 2 tbsp cream or milk, plus more if needed
- Gel food coloring if desired
- Sprinkles for finishing
Instructions
- Preheat Oven: Preheat your oven to 350°F (180°C). Grease and line a 9×13-inch (20x30cm) pan with parchment paper, allowing an overhang for easy removal of the cookie bars once baked and cooled.
- Mix Wet Ingredients: In a stand mixer with the paddle attachment or using a handheld electric mixer, cream together 225g of softened unsalted butter and 300g granulated sugar on high speed until the mixture is light and fluffy. Add 1 large egg and 1 teaspoon vanilla bean paste or vanilla extract, mixing until combined.
- Combine Dry Ingredients: Sift together 320g all-purpose flour, 1 teaspoon kosher salt, and 1/4 teaspoon baking soda in a separate bowl. Gradually add this dry mixture to the wet ingredients and mix until just combined, careful not to overmix.
- Prepare Dough in Pan: Transfer the cookie dough to the prepared pan and spread it evenly using an offset spatula. Optionally, sprinkle granulated sugar on top for added texture and sweetness.
- Bake Cookie Bars: Bake in the preheated oven for 20 to 25 minutes until the tops are lightly golden brown and the center appears set. The edges will slightly crinkle and the bars will deflate a bit upon removal from the oven.
- Cool Cookie Bars: Remove from the oven and place the pan on a wire rack. Let the cookie bars cool completely in the pan before frosting.
- Make Buttercream Frosting: In a clean stand mixer bowl fitted with the paddle attachment, whip 170g of softened unsalted butter with 1 teaspoon vanilla bean paste and ½ teaspoon salt until pale and creamy. Sift in 380g powdered sugar and mix on medium speed until well incorporated.
- Adjust Frosting Consistency: Add 2 tablespoons of cream or milk, one tablespoon at a time, until the frosting is light, fluffy, and spreadable. Mix in gel food coloring if desired to achieve your preferred color.
- Remove Air Bubbles: Run the mixer on low speed for 2-3 minutes to eliminate air bubbles, ensuring a smooth frosting texture. Use the frosting immediately or cover tightly with plastic wrap pressed directly on the surface to prevent crusting.
- Frost Cookie Bars: Using the parchment paper overhang, lift the cooled cookie bars out of the pan and place on a cutting board or serving platter. Spread the buttercream frosting over the cookie bars using an offset spatula or the back of a spoon. Decorate with sprinkles if desired.
- Chill and Slice: Chill the frosted cookie bars just until the frosting sets to make cutting cleaner. Use a sharp knife, wiping it between cuts, to slice into 20 servings.
- Store: Keep the cookie bars in an airtight container at room temperature or in the refrigerator for up to five days to maintain freshness.
