I’ve been obsessed with Biscoff cookies for as long as I can remember. When I was younger, I managed to collect at least three packets per plane ride (two from the flight attendants, one from my dad), and I’d finish all six cookies before my sisters had even started on their first. I love the crunchiness, the shape, and that signature spiced brown sugar flavor, which has now been reimagined into the popular Biscoff Cookie Butter Spread

Until recently, I resisted the urge to purchase the spread, knowing as soon as I opened the jar I wouldn’t be able to close it. (Plus, it’s sort of nice to save my Biscoff moments for plane rides). But all of that changed when I came across this popular 3-ingredient Biscoff cookie recipe posted by Stephanie Kim (aka stephaniekimchi) on TikTok. 

In Stephanie’s video, she makes tiny thumbprint-like cookies out of just three ingredients: Biscoff spread, all-purpose flour, and milk. And, as if this wasn’t intriguing enough, she bakes them in her air fryer. Considering my love for both Biscoff cookies and my air fryer, I knew I had to try them. Here’s my honest review.

How to Make the TikTok Viral 3-Ingredient Biscoff Cookies

Stephanie’s video doesn’t include a ton of detail, but I was able to fill in the gaps. You’ll start by combining 65 grams of cookie butter (if you don’t have a scale, this is about 1/4 cup) with 40 grams of all-purpose flour (about 1/3 cup) and 2 tablespoons whole milk. Use a rubber spatula (and a fair amount of force) to stir the ingredients together until no streaks of flour remain. 

The next step is rolling the dough into balls. Her cookies looked pretty small, so I gathered up just two teaspoons of dough per ball, leaving me with 11 balls total. Then, I used a 1/4 teaspoon measuring spoon to make an indent in the center of each one. 

Stephanie bakes her cookies on a rack in her air fryer, but mine only has a basket. After taking a look at these air fryer chocolate chip cookies, I decided to preheat my air fryer for five minutes (her recipe calls for 320°F; the closest mine gets is 325°F), and then line the basket with parchment paper. Arrange the cookies in a single layer and air-fry until lightly browned and firm to the touch, about 10 minutes. 

While the cookies are frying, dollop some more Biscoff spread into a bowl. Warm it in the microwave in 10-second increments until it’s loose enough to drizzle. Then, transfer it to a piping bag or a plastic zip-top bag with the corner snipped off. Fill the wells of each baked cookie with the warm spread, then dig in!

My Honest Review of the TikTok Viral 3-Ingredient Biscoff Cookies

I was expecting these to be good (how could they not be?!) but I wasn’t expecting them to be this good. Between the soft and chewy cookie and the melty spread instead, every bite was packed with my favorite flavor in the world. I was worried they would lose their appeal as they cooled, but I was wrong: They tasted great for several days following. 

Even though you’re essentially making a cookie out of a cookie, the bite-size thumbprints taste totally different than classic Biscoffs. Plus, they serve a different purpose. If you’re craving a warm, freshly baked cookie but don’t want to take a trip to the store, fuss with a lengthy recipe, or even turn on the oven, these will absolutely hit the spot. They’re sort of like a mug cake in that sense! 

These cookies are also great for last-minute guests, or for bringing to parties or potlucks. I brought them to a movie night a few hours after I baked them, and they were devoured before we even turned on the TV.

If You’re Making the TikTok Viral 3-Ingredient Biscoff Cookies, a Few Tips 

  1. Check on them a few minutes early. Every air fryer is different, so check on them at the 8-minute mark to ensure they don’t overbake. 
  2. Top them with flaky sea salt. A cookie made almost entirely out of cookie butter is delicious, but very sweet. A sprinkle of salt helps balance out the flavors. 
  3. Double the recipe, then cook in batches: These cookies are so good and so small that everyone will want at least three. Plan accordingly and consider making a second batch.
