These Buttery Bar Cookies Are Perfect for Any Occasion
These spring sugar cookie bars are soft, buttery, cheerful, and wonderfully easy to make. They have the sweet vanilla flavor of a classic sugar cookie, but instead of rolling and cutting individual cookies, the dough is pressed into one pan, baked until lightly golden, and finished with a thick layer of fluffy buttercream frosting.
Spring always seems to arrive with a busy calendar. Graduations, luncheons, bridal showers, baby showers, confirmations, Mother’s Day celebrations, and family get-togethers can appear almost overnight. When you need a colorful dessert that looks festive without requiring hours in the kitchen, these frosted sugar cookie bars are a perfect choice.
The pastel sprinkles are mixed right into the cookie dough and scattered generously over the frosting. They add a little crunch, a pop of color, and a happy springtime look that makes these bars stand out on any dessert table. They are rich and sweet, so smaller pieces are just right for serving.

Another great thing about these buttery cookie bars is how well they keep. Store them in a tightly covered container, and they will stay fresh for several days. That makes them a convenient make-ahead dessert for parties, potlucks, and holiday trays.
Why You’ll Love These Spring Cookies
These spring sugar cookie bars are simple, pretty, and dependable. The dough comes together with basic pantry ingredients, and there is no need to chill, scoop, or shape it. Just mix, press, bake, cool, frost, and slice.
You can also customize them for almost any season or holiday. Use pastel sprinkles for spring, red and green sprinkles for Christmas, pink and red for Valentine’s Day, green for Saint Patrick’s Day, or red, white, and blue for the Fourth of July. You can also tint the buttercream with food coloring to match your celebration.
The texture is one of the best parts. These bars are thick, chewy, and tender, with a buttery crumb that is close to shortbread but softer. The creamy buttercream frosting adds sweetness and a smooth finish that makes every bite feel special.
How To Make Spring Cookies
Preheat your oven to 350 degrees. Line an 8-inch or 9-inch square baking pan with parchment paper so the cookie bar can be lifted out easily after baking. A 9-inch pan will make slightly thinner bars, while an 8-inch pan will make them a little thicker and may require a slightly longer baking time.
In a large mixing bowl, cream the softened butter and sugar together until the mixture is light and fluffy. Beat in the eggs and vanilla until smooth. If you are using unsalted butter, add the salt listed in the recipe. If you use salted butter, you can omit the added salt.
Stir in the flour and baking powder until no dry flour remains. The dough will be thick and heavy, which is exactly what you want for a chewy sugar cookie bar. Gently fold in the sprinkles at the end so they stay colorful and evenly distributed.

Press the dough evenly into the prepared pan. You can use clean hands or the back of a spoon to smooth the surface and push the dough into the corners. Try to keep the thickness as even as possible so the bars bake uniformly.
Bake for about 20 minutes, or until the top is lightly golden brown. Do not overbake if you want soft, chewy cookie bars. Remove the pan from the oven and place it on a cooling rack. When the pan is cool enough to handle, lift the cookie bar out using the parchment paper and let it cool completely before frosting.
While the cookie base cools, prepare the buttercream. Beat the softened butter, powdered sugar, vanilla, and milk until the frosting is smooth, light, and fluffy. Add a little more milk if the frosting is too thick, or a little more powdered sugar if it is too thin.

Spread the frosting over the completely cooled cookie bar, then add sprinkles, chips, or candies on top as desired. For neat servings, cut the bar into one-inch-wide strips and divide each strip into thirds. You can also cut the pan into 24 squares if you prefer a more traditional bar shape.

Pastel sprinkles give these cookies a sweet spring look, but the recipe is easy to adapt. A pale yellow, pink, blue, or lavender buttercream would look beautiful for showers and spring parties. However you decorate them, these frosted sugar cookie bars are bright, festive, and delicious.

These spring cookies are a lovely dessert for family meals, brunch tables, bake sales, and celebrations. They are easy enough for a weekday baking project but pretty enough for a special occasion.
