Sugar cookie bars with flower buttercream

I came across a sugar cookie bar I really wanted to make, but didn't have sour cream at home.  We won't talk about the fact that I was at Trader Joe's earlier today -- before I found this recipe -- and reminded myself I wanted to get sour cream in case I made chocolate cupcakes later.  Great reminder, since I left the store without it!

But I digress.

I couldn't make the original sugar cookie bars I wanted to make, but that didn't stop me.  A quick internet search yielded a few other bar recipes (one used cream cheese, which I also didn't have), and I ended up choosing one from Lauren's Latest (remember those recent to die for chocolate chip cookies?  Yeah, those were hers, too, so I knew these bars had to be good!).

I made one and a half times the recipe for the icing, though, because I bought myself a little birthday gift today.  Well, really a few.  I've been eyeing those Russian flower piping tips for a while, and today at the baking store I bought myself 2 sets of them!  I decided that these would be the perfect decoration for the sugar cookie bars, and after I made a HUGE amount of frosting, I divided it up and dyed it different colors, so that I could have a flower garden on top of my sugar cookie bars!  Now all I need to do is perfect my icing leaves!

Sugar Cookie Bars with Flower Buttercream
Recipe from Lauren's Latest, Icing decorations by me

Ingredients:

For the Cookie Bars:

1 cup softened butter
1 cup granulated sugar
1 large egg
1.5 teaspoon vanilla
1 teaspoon almond extract
3 cups all purpose flour,
1 teaspoon baking powder
1/2 tsp salt

For the icing (remember, I 1.5 times'd the recipe, listed below is the original recipe):

1/2 cup softened butter
1 pound powdered sugar
2 teaspoons vanilla extract
3-4 Tablespoons milk
Sprinkles, if desired

Directions:

Preheat oven to 350 degrees.
Line a 9 x 13 inch baking pan with parchement paper.
Lightly spray with nonstick cooking spray.
Set aside.

In a large bowl, stir butter and sugar together until light and fluffy.
Stir in egg, vanilla, and almond extract.
Whip until fluffy.
Scrape the sides and stir again briefly.
Stir in remaining dry ingredients and mix until just incorporated.
It won't come together as a dough initially, but if you can grab a handful, it should hold it's shape.
Spread dough into prepared pan and press down evenly.
Bake 20-25 minutes or until edges are golden brown.
Remove from oven and cool completely.

Make the frosting.

Stir all ingredients together until smooth and fluffy, except for milk.
Start by adding 3 tablespoons of milk and work up from there until frosting is the desired consistency.
If making bars as I did, continue below at the *.
If making the bars as intended, Spread icing over cooled cookie bars.
Add sprinkles if using (if you can believe it, I didn't use sprinkles this time).
Cut into bars and serve.
