The Only Cookies Santa Will Want to Eat

Are you baking cookies this time of year? Sometimes, I think that’s all I do, but I’m not complaining! With recipes like No-Bake Chocolate Pecan Cookies, PB Stuffed Chocolate Chip Cookies,White Chocolate Pistachio Cookies, and more, there’s never a shortage of sweet treats in my house, but it’s not my fault! You see, clearly, I’m on the nice list this year. So, I’m just doing my duty in finding the best cookies to leave out for Santa, and that means tasting them all just to make sure. You feel me? However, in my cookie baking endeavours, one cookie recipe has stood out from all the rest! This eggnog cookie is by far the winner, and quite honestly, I cannot get enough of it. 

Made with protein, oat flour, and eggnog butter, it’s everything you never knew you needed in a cookie recipe and so much more. Not only is it super soft, but they’re also full of warm spiced eggnog flavor for an explosion of holiday flavor. Did I mention it can also be made in the microwave in just 1 minute? Yep, you read that right! That means you can definitely sneak one in while your little ones nap. Or, is that just me? Either way, you definitely don’t want to miss out on making this eggnog cookie recipe…for Santa, obviously. Keep reading to find everything you’ll need! 

Ingredients for Eggnog Cookies

For this recipe, I broke the ingredients into two sections, one for the cookie itself and another for the frosting which is optional (but really isn’t). 

For the Cookies

Eggnog Butter – Don’t fret, this is nothing crazy!! In fact, its just nut butter that is spiced to taste like eggnog. If you don’t have it or can’t find eggnog butter, you can make a simple swap! Try using an equal swap of cashew butter, ⅛ tsp nutmeg, a pinch of cinnamon and a tiny splash of vanilla extract.

Protein Powder – As always, I used Nuzest protein (code: thekellykathleen to save some money) in the vanilla flavor. However, any protein powder you have on hand can be used. Just keep in mind that the flavor and texture of your eggnog cookies may vary depending on what kind you use. 

Milk – I opted for soy milk for this recipe, but any milk you prefer works just as well. 

Flour – To keep this recipe gluten-free, I used pre-made oat flour. However, you could definitely make your own by pulsing whole oats in a food processor or high-speed blender until a fine, powder-like texture is formed! 

Baking Essentials – You’ll also need salt and baking soda to enhance the flavors of this eggnog cookie recipe and create a fluffy texture. 

For the Frosting

To make the frosting for your eggnog cookies, you’ll want to save some milk, eggnog butter, and vanilla protein! Or, feel free to use a store bought frosting instead. I recommend sticking with a fairly neutral flavor so you don’t overpower the eggnog.

Optional Add-Ins

For even more flavor and texture, try adding in extra ingredients such as chocolate chips, peppermint pieces, cinnamon, caramel, or even cheesecake bites! Or, try adding a dash of cinnamon and nutmeg to enhance the spice of the eggnog. 

How to Make this Eggnog Cookie Recipe

You guys, I’m about to blow your mind with how easy these cookies are to make. Just follow the 4 easy steps below!

  1. Mix. To start, mix all of the cookie ingredients in a bowl until they are well-combined.
  2. Form. Next, wet your hands, and form the dough into a cookie shape. 
  3. Microwave. Place the formed cookie on a lightly oiled plate, and microwave it for 1 minute.
  4. Frost. Let the microwaved cookie sit for 5 minutes to set and cool, and top it with your homemade frosting (or frosting of choice). 

How to Make the Frosting

To create your own frosting, whisk the ingredients in a small bowl until they are smooth and creamy. If your frosting is too dry, add a bit more milk until the desired consistency is reached. Or, if your frosting is too runny, add dashes of protein powder, stirring until it thickens. 

Make a Festive Cookie

Tis the season, am I right? If you want to have a little fun with your eggnog cookie, try giving it a festive flair! Some of my favorite ways to do so include: 

  • Shaping them with a cookie cutter
  • Adding sprinkles
  • Creating a design with icing 
  • Add food coloring

Can I Make More than One Cookie? 

Sure! If you want to make a big batch of these cookies, just multiply the ingredients by the number of cookies you want to make. Admittedly, I have not tried them in the oven. However, they should bake at 350 degrees for about 8 minutes. Just be sure to keep an eye on them! 

Storage Options

If you want to make several cookies ahead of time, they’re super easy to store! Just place them in an airtight container, and store them at room temperature for 1-2 days. Or, store them in the fridge for up to 4 days!

For an even longer storage option, place your eggnog cookies in the freezer for up to 6 months. However, if you place them in the freezer, I recommend skipping the frosting until you’re ready to eat them.
