Buttermilk Cookies with Honey Buttercream Frosting

Buttermilk Cookies with Honey Buttercream Frosting are like the top of a cupcake – soft, fluffy, and loaded with frosting. They are light, perfectly sweet, and so delicious.

I made these cookies to use up some leftover buttermilk, and WOW, they are so good. I started making buttermilk muffins the same way – as a way to use up leftover buttermilk – I’m starting to realize that buttermilk is such a wonderful and versatile ingredient.

These cookies are a little different than the Amish Cookies that use brown sugar – these are more of a cakey cookie, which I normally would not willingly choose – but these are SO good. (I normally am one to choose the chewy, melt-in-your-mouth chocolate chip cookies – not one with a cake-like texture – but these cookies are just so delicious in their own way.)

These buttermilk cookies have just the right amount of sweetness – they are a little plain on their own, but when combined with the honey butter frosting – it’s almost like a sweet muffin top with melted honey butter. The wonderful flavors come together so well. They are such a different kind of cookie – and they are so delicious.

🥘 Ingredients Needed

For the Cookies

• Butter, softened
• Sugar
• Egg, room temperature
• Vanilla Extract
• All-purpose Flour
• Baking Soda
• Kosher Salt
• Buttermilk – Buttermilk is one of the staple ingredients in this recipe. I would not use a homemade buttermilk substitute here (the kind you make by mixing a tablespoon of lemon juice or a tablespoon of white vinegar with a cup of regular milk.) You really do taste the tang of the buttermilk in the base of the cookie, and I would be worried that the substitute wouldn’t have quite the same taste.

For the Frosting

• Butter, softened
• Honey
• Powdered Sugar
• Kosher Salt

Optional

• Sprinkles
• Chopped Nuts
• Chocolate Chips

🍽 Equipment Needed

• An Electric Mixer – You can use either a stand mixer or a hand mixer. I like the stand mixer because it is easier to use once you start adding flour!
• Cookie Sheets with Parchment Paper or Non-Stick Baking Mats/Silpats
• A Cookie Scoop

How to Make Buttermilk Cookies

For the Cookie Dough

• Preheat the oven to 375° and line a baking sheet with either parchment paper or a silicone baking mat.
• Cream butter and sugar together until the mixture is light and fluffy. Beat in the egg and then the vanilla extract.
• In a separate bowl, whisk flour, baking soda, and salt together.
• Add the dry ingredients to the butter mixture with the mixer at a low speed, alternating with the buttermilk, beating well after each addition and scraping down the sides of the bowl as needed. (Add the flour mixture in small amounts so that the flour doesn’t explode everywhere.) The dough will be sticky but should be manageable.

• Roll the cookie dough into balls, about a tablespoon to a tablespoon and a half in size, and place the rounded tablespoonfuls onto a cookie sheet about 2 inches apart. (They will spread a little.)
• Bake for 10-12 minutes, until the edges are lightly browned.

• Place the cookies on wire racks to cool.

For the Honey Butter Frosting

• To make the frosting, cream softened butter with your mixer – I use the whisk attachment to kind of whip it – then whip it with the honey to get it kind of soft and fluffy like whipped honey butter.
• Add in half of the confectioners’ sugar, then when fully incorporated, add the remaining powdered sugar and salt. Beat until smooth. If you want the frosting to be runnier like icing, you can add a little milk, but I like this frosting like cupcake frosting – it is SO good.

Let the cookies cool, then spread the thick frosting all over the cookies. If desired, sprinkle with sprinkles or chopped nuts.

Make sure the cookies are mostly cooled before frosting them, or the frosting will melt off of the cookies. (Though honestly, if you are just enjoying them at home – it is delicious to spread some frosting on the warm cookie and let it melt a little. It is just like melting honey butter on a warm muffin.)

This is such a simple cookie, and they have such an amazing flavor – they are soft and subtly sweet and make a great treat to bring to family gatherings.

🙋‍♀️ Frequently Asked Questions

✏️ Helpful Tips

• Use a cookie scoop to make the cookies more uniform in size.
• Add the flour mixture slowly with the mixer at a low or medium speed so that the flour doesn’t explode everywhere.
• Use a non-stick baking mat (I use a Silpat) to keep the cookies from sticking to your baking sheet. This also keeps the bottoms of the cookies from cooking too fast. (Dark cookie sheets also tend to heat up quickly, and the bottoms of cookies will burn, so try to use a lighter cookie sheet.)
• If you are making multiple batches of cookies, allow your cookie sheet to cool in between batches or use multiple cookie sheets.
• Make sure that your rack is in the center of the oven when baking cookies – too close to the top or bottom of the oven can result in uneven baking.
