The BEST Butter Crunch Cookie Recipe
We’ve sort of established ourselves here as a soft & chewy kind of blog. Most of the time, that’s my go-to. Give me gooey butter cookies, chocolate chip cookies that stay soft for days or snickerdoodles any day, and I’ll gladly gobble them up. Today, though, I’m flipping the script and sharing these snappy, crisp, butter crunch cookies. They are perfectly brittle (never thought I’d say that about a cookie) and snap satisfyingly in your teeth.
These are thin, crunchy, super buttery cookies made with rich and cozy browned butter. Toffee bits complement the brown butter flavor beautifully, (those of you who have obsessed over my soft & chewy brown butter toffee cookies know this already). They’re packed with texture and flavor, and they’re so much better than store-bought.
This recipe is super unique and fun! It’s also easy; the most involved step is browning the butter, and and even that isn’t difficult.
Why you’ll love my recipe:
- Simple–less than 10 ingredients.
- Just 15 minutes of prep!
- Incredible flavor and texture.
- No chilling!
What You Need
Look at that–only 9 ingredients to make this recipe! Here are they key ingredients for butter crunch cookies:
- Butter. I generally prefer to use unsalted butter and add salt myself (it’s just more precise!). I know many of you only buy salted butter though, so if that’s all you have, you can reduce the salt in the recipe to ½ teaspoon.
- Sugar. We’ll use a combination of light brown sugar and granulated sugar. Yes, it’s a lot of sugar, but this ratio is what gives these butter crunch cookies their crunch!
- Toffee bits. Some toffee bits are sold without chocolate, and some are sold with chocolate on them; use whichever you prefer, as both are excellent here. Homemade toffee bits would also work!
- Baking soda. Not to be confused with baking powder! Baking soda encourages the cookies to be crisp and crunchy–it’s a key ingredient here.
- Vanilla. A full tablespoon of vanilla extract really complements the buttery, toffee flavor.
SAM’S TIP: It’s very important that you measure your flour properly for this recipe (and most others). In this recipe, adding too much flour could prevent your cookies from spreading, and we want these nice and thin!

How to Make Butter Crunch Cookies
- Melt butter over medium-low heat, then increase the heat to medium and stir constantly as the butter pops and sizzles.
- Once brown flecks form and the popping slows, remove the butter from the heat and pour into a heatproof bowl to cool completely.
- Cream together the cooled, re-solidified butter and sugars.
- Stir in the egg and vanilla extract.
- Combine the dry ingredients in a separate bowl, then gradually stir them into the wet ingredients.
- Add the toffee bits and stir until combined.
- Scoop the dough onto a parchment lined baking sheet and bake for 10-12 minutes. they should be a nice golden brown color.
- Let the cookies cool completely on the baking sheet before enjoying.
SAM’S TIP: While warm or straight off the baking sheet, the bottoms of your cookies will have a bit of brown butter grease on the bottom. You can just dab them on a paper towel if this bothers you; I just lick it off my fingers when I’m done eating 🙃
Frequently Asked Questions
This recipe has a high sugar content, which is critical to making a thin, crispy cookie (like my thin & crispy chocolate chip cookies). Cooking the water out of the butter when we brown it also lends itself to a crisp, delicate cookie. And finally, baking soda helps the cookies spread out and encourages a porous, brittle texture. In case you didn’t believe it before, baking truly is a science!
While my cookies never make it long enough in my house to consider freezing, I think these would freeze just fine. If freezing in layers, place sheets of wax paper between the cookies so they don’t stick together.
These cookies are designed to spread a good bit, but if yours were a runny mess, then your butter may have been too warm when you added the sugars. You want to make sure you plan for at least an hour of cooling time for your butter so it can re-solidify after browning. Unfortunately if this happens, nothing will fix your dough (not even chilling!).
Whether you’re team thin & crispy or soft & chewy, these cookies are sure to satisfy your sweet tooth ❤️
