Swig Cookie Blondies
Swig Cookie Blondies are sensational. Really. You’ve heard of Swig Sugar Cookies. These are very similar but made into bar form instead. Yes, they certainly are scrumptious. Of course, I just love anything with icing. In fact, I have difficulty stopping when cookies have icing!

Truthfully, it would be better to refrigerate the bars a couple of hours before cutting so the icing can set up a little more. Since the icing is made with sour cream, you really need to keep these bars refrigerated after baking them and applying the icing.
Back in early December I made Swig Sugar Cookies for our Christmas in Ovilla gala that our church was hosting for our small town here in Texas. (I include them in my Christmas Cookie Extravaganza). While I made a double batch of the cookies and the icing, I had SO much icing left over that I really didn’t want to throw it away.
I decided to make another batch of the cookies into blondies and add some sprinkles (always a winner). I gave them to the young teenage boy who takes care of our dogs when we travel. He’s not a big sweets eater but he enjoys my treats, and I heard they vanished rather rapidly. 🙂
If you’re looking for a divine iced blondie recipe, you’ve got to give Swig Cookie Blondies a try. They’re really to die for. Bring them to any potluck or party and watch them disappear.

Swig Cookie Blondies are incredibly delicious.

I didn’t have time to allow the blondies to refrigerate for several hours before taking pictures. The icing wouldn’t have drizzled down the sides quite so much. 🙂

Sprinkles on top of the blondies add a delicate color and sparkle to these cookies.
Here’s what I did.

I used these ingredients for the blondies plus water.

Place softened butter, oil, sugar, powdered sugar, eggs, cream of tartar, baking soda, salt and water in a mixing bowl.

Mix with an electric mixer until smooth.

Add UNBLEACHED all-purpose flour. Bleached flour toughens baked goods.

Stir ingredients with a wooden spoon until combined. You can also mix on very low speed of electric mixer until well combined.

Press ingredients into a greased 9×13″ glass baking dish.

Bake at 350 for 25-30 minutes or until a toothpick inserted in center comes out clean. Cool completely before adding icing.

I used these ingredients for the icing. (The next time I made the recipe, I skipped the milk. It was perfect without it.)

While blondies are baking, make icing: Cream butter with sour cream, vanilla and salt. Add powdered sugar and cream again. You should actually add the powdered sugar about 1/3 to 1/2 cup at a time and work in slowly until all the powdered sugar has been added.

Add red food coloring and mix again.

Here the icing is ready. Refrigerate until ready to use. (I doubled the ingredients so this is much more icing than the regular amount).

Spread icing over top of cooled blondies. Sprinkle with funfetti sprinkles. Allow bars to set up in refrigerator a couple of hours before cutting into bars.

Swig Cookie Blondies are amazing. They’re great for holiday baking, too.

Swig Cookie Blondies are a great dessert to make anytime you have company.

Swig Cookie Blondies will become some of your favorite cookies.
