I make these soft and buttery frosted sugar cookie bars whenever I crave a classic vanilla dessert that feels comforting and festive at the same time. They have a tender, cake-like texture with rich vanilla flavor, topped with a smooth and creamy frosting that melts right into every bite.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup unsalted butter, softened

1 1/2 cups granulated sugar

2 large eggs

1 tablespoon vanilla extract

2 3/4 cups all-purpose flour

1 teaspoon baking powder

1/2 teaspoon salt

For the Frosting:

1/2 cup unsalted butter, softened

2 cups powdered sugar

2 tablespoons heavy cream (or milk)

1 teaspoon vanilla extract

Pinch of salt

Sprinkles for decorating (optional)

Directions

I start by preheating the oven to 350°F (175°C) and lining a 9×13-inch baking pan with parchment paper or lightly greasing it.

In a large mixing bowl, I cream together the softened butter and granulated sugar until light and fluffy, which usually takes about 2–3 minutes. I add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

In a separate bowl, I whisk together the flour, baking powder, and salt. I gradually add the dry ingredients to the wet mixture, mixing just until combined. I make sure not to overmix so the bars stay soft.

I press the dough evenly into the prepared baking pan using a spatula or lightly floured hands. Then I bake for 18–22 minutes, just until the edges are lightly golden and the center is set. I avoid overbaking to keep the texture soft and tender.

I let the bars cool completely in the pan before adding the frosting.

For the frosting, I beat the softened butter until smooth. I gradually mix in the powdered sugar, then add the heavy cream, vanilla extract, and a pinch of salt. I beat everything until the frosting is light and fluffy. I spread it evenly over the cooled bars and finish with sprinkles before slicing into squares.

Variations

I sometimes swap the vanilla extract in the frosting for almond extract when I want a slightly different flavor profile. For a fun twist, I mix colorful sprinkles directly into the batter to create a festive confetti version.

When I want a richer taste, I brown the butter before mixing it into the dough, which adds a subtle nutty depth. I also like adding a few drops of food coloring to the frosting to match special occasions or holidays.

Storage/Reheating

I store these bars in an airtight container at room temperature for up to 3 days. If I want them to last longer, I refrigerate them for up to 5 days, making sure they are well covered to prevent the frosting from drying out.

If I prefer a slightly warm bar, I let it sit at room temperature for about 20 minutes before serving. I avoid microwaving frosted bars for too long, as the frosting can melt too quickly.

FAQs

How do I keep the bars soft?

I make sure not to overmix the dough and avoid overbaking. I take them out of the oven as soon as the center is set and the edges are lightly golden.

Can I make these bars ahead of time?

I often bake the bars a day in advance and frost them the next day. I keep them covered tightly to maintain freshness.

Can I freeze sugar cookie bars?

I freeze the unfrosted bars tightly wrapped for up to 2 months. When I am ready to serve, I thaw them at room temperature and add fresh frosting.

Can I use salted butter instead?

I can use salted butter, but I reduce or omit the added salt in the recipe to balance the flavor.

What size pan works best?

I use a 9×13-inch pan for perfectly thick and soft bars. Using a smaller pan makes them thicker and may require slightly longer baking time.

Conclusion

I always come back to these soft and buttery frosted sugar cookie bars because they are simple, reliable, and full of classic vanilla flavor. They are perfect for gatherings, holidays, or whenever I want an easy homemade dessert that everyone enjoys.
