Pin a Day: Sugar Cookie Bars with Buttercream Frosting

On Wednesdays, I bake for trivia.  This week, I tried a new recipe for Sugar Cookie Bars with Buttercream Frosting.   These bars turned out great, however, they were definitely not healthy.  I could tell that when the recipe called for 1 lb of butter.  Fortunately, the beer lovers at Whitestone aren't all too worried about their figures, so I warned them, but most happily enjoyed these new treats.  I like to make bars because they are relatively easy, they don't have to look especially pretty, and they make plenty for a crowd.  I ended up giving away about half last night, so Mike had some to take to his work friends this morning.  I started by mixing together 2 sticks of softened butter, vegetable oil, vanilla, sugar, and powdered sugar until it was smooth.  Next, I added in the eggs.  Finally, I gradually mixed in my dry ingredient combo of flour, baking soda, salt, and cream of tartar.  Once the batter was well combined, I smoothed it in to a lightly greased 9x13 pan.  The bars baked for about 20 minutes.  I let them cool completely and made the frosting.  For the frosting, I mixed together 2 sticks of butter, powdered sugar, and a little bit of milk.  I spread the frosting on the bars and let it set at room temperature.  When I picked up the pan to take to trivia, I was a little shocked at how heavy it was.  I cut the bars before we left and when I served them, I was surprised that they felt light as individual bars.  They seemed to be a hit, but they were quite sweet and filling.  These were good, but they didn't have chocolate, so they may not be repeated too much in our house.  A couple of changes we might make in the future include: a lemon frosting instead or adding a little vanilla or other flavoring to the frosting.
