I’ve had these Soft Sour Cream Sugar Cookie Bars photos in my drafts for a long time—since September—waiting for the perfect time to post them. Fall was mostly spent getting back in the swing of things after my self-imposed break, and then there were the holidays, and then the post-holiday malaise. The Super Bowl or Valentine’s Day would have been a perfect time to post these, but I *just* posted those Vanilla Sour Cream Cupcakes and…
…well, there’s just never going to be a perfect time, is there? Or maybe anytime is a perfect time? I don’t know. This is confusing.
What I do know is that these Soft Sour Cream Sugar Cookie Bars are spectacular. They’re a riff on my Soft Sour Cream Sugar Cookies (which are a riff on Lofthouse Cookies), but they’re bars, ya know? The cookie layer is thick and a little cakey; perfect for pairing with a thick layer of Vanilla Sour Cream Frosting! I made mine pink because pink food just tastes better, as does anything with way too many sprinkles on top.
These are a great dessert for a multitude of occasions and non-occasions alike. Might I recommend this three day weekend in the middle of February? Seems like a perfect time to me.
Soft Sour Cream Sugar Cookie Bars
makes 1 9x13-inch pan (24 bars)
Dough:
2 1/3 cups all-purpose flour
1/2 cup confectioner’s sugar
1 teaspoon baking powder
1/8 teaspoon baking soda
1/2 teaspoon Kosher or sea salt
1 cup (2 sticks) unsalted butter, softened to room temperature
1 cup granulated sugar, packed
1 large egg, room temperature
1/3 cup sour cream (not fridge-cold)
2 teaspoons pure vanilla extract
For Decorating:
Vanilla Sour Cream Frosting (recipe below)
sprinkles of choice
Preheat oven to 350F. Grease a 9x13-inch pan (or quarter sheet pan) with butter. Line with parchment, leaving some overhang on the long sides, and butter again. Set aside
Make the dough. In a medium mixing bowl, whisk together flour, confectioner’s sugars, baking powder, baking soda and salt. Set aside.
In a medium-large mixing bowl, use an electric mixer to beat butter until light and fluffy, about 2 minutes. Beat in sugar until creamy. Mix in egg, followed by sour cream and vanilla. Add dry ingredients in 2 installments, beating until combined. Dough will be sticky.
Drop large spoonfuls of dough into the prepared pan, make sure to use it all. Use an offset icing spatula or the back of a spoon to spread dough in an even layer to the edges of the pan.
Transfer the pan to the oven and bake 23-25 minutes, until the edges are turning golden and the center has puffed. Let bars cool completely in the pan on a rack. Meanwhile, make the Vanilla Sour Cream Frosting (recipe below).
Once the bars are cool, run a thin flexible knife along all the edges to release them from the pan. Use the parchment overhang to transfer them to a cutting board or other surface. Drop spoonfuls of the frosting over the top of the bars. Use an offset icing spatula or the back of a spoon to spread it evenly to the edges. Finish with your sprinkles of choice.
For the cleanest slices, refrigerate the assembled bars for at least 20 minutes before slicing into 24 pieces with a large, sharp chef’s knife.
After they’ve crusted, leftovers may be layered with wax or parchment paper and kept in an airtight container. They will keep at room temperature for a couple of days or in the refrigerator for up to a week.

I know that restrictions are starting to loosen as vaccines becomes more available, but if you’re not attending gatherings that require a cake of this size, don’t worry, I’m not either. What that means is that I happen to know that this recipe halves well and can be baked in a loaf pan for your immediate pod or just yourself. I don’t know about you, but dipping into my own personal Funfetti cake over the course of a week sounds a lot like happiness to me.
