Chocolate chip cookies made with brown butter and rye flour which gives them an earthy, nutty flavor. These have crispy edges and a wonderfully chewy center.
These days, whenever I go to an artisan coffee/bakery shops I find myself face to face with a display of cookies and usually one of them is a rye variety: rye brownie (I’ve been working on trying to replicate that one for ~2 years now and I’ve not yet been successful), rye chocolate chip, rye and nuts…
Plus, since I started maintaining a sourdough I tend to keep a medium rye on hand more often, so I figured lets try it in a cookie.
Initial results were… not great; rye doesn’t really behave like all purpose. It’s got a lot less gluten in it so you need to add more than a 1:1 swap (a lot of very flat rye cookies still haunt me); it’s heartier (I think of it as being similar to whole wheat flour in that sense, or maybe like oat flour) and has a forward flavor; kind of nutty and earthy.
Ryes natural ‘nutty’ flavor profile is what got me to turn to this brown butter chocolate chip recipe as a starting point. I’m always looking to amp up a nutty flavor by browning the butter but this sometimes can also produce flatter cookies, because you’ve lost some of the creaminess in the process.
To counteract this problem, I added in a bit of milk which helps bring the sugar and butter mixture back to the correct moisture/creamy texture. I went for the full egg, knowing that the white of the egg would give the cookies more structure. I also added a chilling period and adjusted my leavening: a little less baking soda kept the cookies from over-spreading.
The result is, well, tbh, it’s kind of like a bakery style rye chocolate chip cookie! It’s got this depth of flavor from rye and brown butter and a wonderful chewy texture that borders on bendy the next day.
Rye Flour
The first thing you should know about rye flour is that you can’t substitute it 1-1 for all purpose. Rye is much heartier and has less gluten. There are also different types of rye: light, medium and dark. Dark rye will give you a bread that almost looks as dark as chocolate. Often some flour millers classify it as pumpernickel (you’ve likely seen those dark bagels with this.).
For these cookies I used a medium rye and I think a light rye would work very well too. Whole rye flour (or dark, or pumpernickel) would be too strong for a cookie.
Chocolate
I used a dark chocolate of 72% cocoa solids (always my preference, keen readers will notice) but this is a flexible recipe: use any chocolate you like, be it chips or a bar; dark or milk. The cookies will spread nicely with either.
Butter
Unsalted, and cold is fine. We’re browning it!
Sugar
Brown sugar takes the cookie into a chewier texture and granulated adds structure.
Vanilla
Pure vanilla extract. Use the good stuff and if you are feeling liberal with it, 2 teaspoons.
Salt
Fine sea salt. If you’re using table salt, which is saltier in flavor, halve the amount.
Egg
One whole large egg.
Brown the butter:
Let the butter cool briefly
Whisk in the sugar:
Add the milk, whisk vigorously (or use a hand mixer) and watch the mix transform:
Add the egg, whisk well and watch it transform:
Stir in the dry ingredients
Fold in the chocolate
Let rest and chill
Prep the pans, preheat the oven
Bake until edges are golden and the center is set:
The day of baking, keep them on a tray. If storing overnight, transfer to an airtight container. The crispy edges will turn chewy and the chewy centers will turn so chewy they’ll be ‘bendy’.
The more I make cookie dough to bake off later, the more I dislike baking them straight from the freezer (unless the recipe is designed that way to start with). Here’s what happens when you bake a frozen cookie that wasn’t meant to be frozen:
Before the butter has a chance to melt, the cookie starts ‘setting’: the sugars caramelize and the proteins ???. This is why often cookies that are baked from frozen will spread less than intended and will have darker edges.
So let’s say you want to make these ahead of time: flash freeze them on a plate, then transfer them to an airtight container. In the freezer they’ll keep for a few months.
When you want to bake them, bring them to a cool room temperature. The dough should not be warm, but it should be soft at a cool room temperature.

Hello! This sounds amazing! Can I ask where do you get your rye flour? Is there a particular brand you like?
Hi! I like king arthur’s medium blend but I also get Bob’s Red Mill occasionally.
