Why this recipe works

Unlike using a glaze which consists of powdered sugar and milk, this frosting has a base of butter and can be frosted onto the cookies or piped. The frosting does not harden right away, so you can be free to frost cookies and decorate them at your own pace. And, if you do want to make it ahead of time, just add 1 tsp milk to the already finished frosting and it softens back up. Really, this frosting is delicious, not to sweet, and perfect for decorating Christmas cookies!

The weekend before Thanksgiving, Tyler and I went away with friends for our annual Friendsgiving. I made this frosting recipe, and sugar cookies, ahead of time so they could have a fun decorating session with Grandma Wendy. Last year, our elementary school did a cookie order, so instead of making my own I totally cheated (while supporting the school of course) and baked up some delicious sugar cookies!

So you know, those idyllic moments one think of while frosting and decorating cookies? Everyone is smiling and having a grand time, making the perfectly frosted and decorated cookies with the ratio of cookie-to-frosting-to-sprinkles to perfection. Yeah, that does not typically happen in our house.

Elliana licks everything. Levi eats everything. Matthew throws cookies. Samuel does it as fast as possible to then be able to leave the table. All I have to say, is my mother y’all is a trooper. She wrangled these rascals and had them decorate four dozen sugar cookies like a champ. Here’s to all those type-A mommas out there who know how to get a job done! Well done mom!

But seriously folks… these kids are just hilarious. Literally after my mom took this picture, her only one of the event, Matthew threw a cookie at Levi and then everything went to hell. The cookies were completed though, so that is a major win! Plus, they are delicious!

With only four ingredients, this recipe for frosting that hardens is fairly inexpensive. To stay on our weekly food budget, buying items like frosting from the store do add up in cost quickly. To cut costs, making food from scratch is the way to go, even with simple things like frosting for Christmas sugar cookie cutouts. One jar of frosting that was 2 cups at ALDI was $1.35. To buy the amount of frosting that I made from scratch would cost $4.05.

Powdered Sugar $1.55
Milk $0.07
Butter $1.30
Vanilla extract $0.01

The total cost to make this frosting was only $2.93 for 4-6 cups of sugar cookie frosting that actually hardens.


2/3 cup butter; softened
1/2 cup milk
2 pounds powdered sugar (8 cups)
1 tsp vanilla
1/4 tsp almond extract

ingredients for sugar cookie frosting and a KitchenAid mixer
Just four ingredients!!!


1. Most importantly, let the butter rest to room temperature, the butter needs to be completely softened, but not melted, so it can blend well.
2. Secondly, place butter into the bowl of a KitchenAid mixer. At first, I used a whisk attachment but then switched pretty quick to using my batter attachment, as the butter just went directly into the whisk instead of creaming with the milk.

3. Measure and then add milk to the butter.

4. SLOWLY cream together the butter and milk until creamy, this may take a few minutes.
Pro-tip- If your butter is not creaming well into the milk, try warming the milk for 10-15 seconds before adding it to the bowl. Or you can warm a rag or a towel with hot water and wrap it around the base of the bowl to help the butter and milk blend easier, as the coldness of the milk can then cause the softened butter to quickly chunk back up.

5. Measure and then add the powdered sugar to the KitchenAid mixer. 8 cups equal an entire 2-pound bag of powdered sugar. Teaching Elliana to keep her hands away from the KitchenAid mixer is my priority #1. She sure loved watching the powdered sugar turn into frosting. To prevent a huge puff of powdered sugar in your face, I recommend that you add the sugar in two or three separate installments and then blend it into the butter milk mixture completely after each addition of powdered sugar.

6. Next, add the extracts and then blend well. This recipe calls for 1 teaspoon vanilla extract and 1/4 teaspoon almond extract, but because of my almond extract, I just replaced it with vanilla. You can choose to use any extracts with this recipe.
There are so many varieties of extracts to choose!

7. Immediately frost sugar cookies that are completely cooled, then decorate them and let the frosting harden. Of course Elliana and I had to taste test one cookie to make sure it was delicious. This frosting is so smooth and there were honestly no clumps.

8. If you are making this frosting ahead of time, and it hardens in a bowl, add 1 teaspoon milk and mix on low until it combines and softens. Our kids frosted these cookies a day after the frosting was made and it still was creamy! By placing small amounts of frosting into multiple bowls and adding food coloring, you can make a variety of different fun colors! Enjoy!

I have not always had the skills to cook and bake from scratch. As a young wife, I bought every meal frozen or boxed and presented it to my husband with a flourish, believing myself a decadent cook. As our budget shrunk, and our family grew, I looked for ways to stretch our money to nourish our kids with the best for their hungry appetites. Hoping to find recipes and meals that they would love to eat. Through the last 5 years, I have learned so many cooking and baking lessons, and experienced many wins and failures. Come along with me on this journey as I share my recipes that work, how to make them on the cheap, and my tips and tricks to get my kids to eat homemade deliciousness! I will also share updates to our house that we have done in the last year since our move. With one income, we do most of the work ourselves and with amazing family and friends to help out, cutting costs but keeping style and money in the bank! I am a wife and mother of 3 boys and 1 princess. When I was a kid, I remember being asked what I wanted to be or do when I grew up. My response was, "a mom", and I am proud to grow up and be a mom to 4 amazing kids! Samuel is 11, Matthew is 8, Levi is 4, and Elliana is almost 2. We have been blessed to have kids who love to explore foods, to try new recipes, and enjoy helping us around the house. With 4 kids, you better believe they help clean! My husband Tyler and I have been married almost 13 years. We love our kids, we love outdoors, camping, canoeing, grilling, watching movies, and just hanging out making memories. A few years ago I gifted Tyler with his own "menu" book, where we write meals and foods we have loved to eat. Weekly our family decides what our meals will be and I make up a grocery list with what we need. It literally is my favorite chore! I love to shop, so shopping for food on a budget is my biggest win!

Keep coming back to hear about new recipes, updates on our home, fun times with our kids, and how to make homemade deliciousness! ~Monica
