It’s officially holiday cookie season! Now that we’ve had some time to settle from all the food we over-indulged on during the Thanksgiving weekend, it’s time to turn our attention to holiday baking! I’m dedicating the entire week here on VV to holiday desserts so if these brownie cookies aren’t your thing, make sure to check back later this week for another cookie recipe and a round-up of my favorite holiday dessert recipes.

What Are Brownie Cookies?

Think of these cookies as brownies in cookie form. With each cookie, you get a crunch from the outer layer and a gooey chocolate inside which will remind you of biting into a brownie. We achieve this outer crunchy layer from egg whites so the texture is similar to the outside of a French macaroon. 

Do I need to plan ahead?

When making this recipe, make sure to start on the rum sugar the night before as it must dry out overnight. This recipe will most likely yield more rum sugar than you’ll need so use the rest to sprinkle into hot chocolate or to sprinkle over pancakes or waffles. Store leftover sugar rum in a sealed container in the fridge for a few days. 

Any TipS For Making Brownie Cookies?

My biggest suggestion for this recipe is to make sure not to over mix the ingredients. I know many of us leans on the stand mixer for all of our baking needs but skip it for this one recipe and whisk by hand. If the dough ends up over mixed then it will become tough and the end product’s final texture will be off.

My last tip is that the dough is really sticky so use two spoons to scoop the dough onto the parchment paper. When doing this, use one spoon to scoop up a tablespoon of dough and then the other spoon to scrap the dough off that spoon and onto your baking sheet.

    Rum sugar. I’d definitely break my newly imposed “no cookies till Christmas” rule for one of these! – a clean eating bento blog

    I had a similar baking marathon at the weekend (and you’re so right about how hard it is to find “interesting” cookie recipes at this time of year) but I’m totally going to have to make a batch of these before the week is out. Rum sugar? I’m so in.

      Yes! I wish you were in the kitchen with me when I was making these so you could have talked me into making a double batch of sugar to save for gifts – such a good idea! What was I thinking?!

    this is a great recipe but a couple of feedback notes. I think on these instructions “Whisk together the sugar, powdered sugar, and salt” you instead meant “whisk together the cocoa, powdered sugar”…also I found that measured everything out but had to re-do via a sift to ensure a smoother batter. also, these were perfect at 10 minutes. thanks so much, the rum sugar is perfection!

    Hello and thank you for this fabulous recipe !!!
    But I am French and I do not know the “tublidado sugar” at all ??? Could you explain to me what kind of special sugar this is …
    Because I imagine that if I take my powdered sugar, it will melt : o ((
    This invension is great, now I have to find this sugar!
    The cookies will console me while waiting for your answer … Thank you for your site

    I think it was a typo – pretty sure it should say turbinado sugar 🙂
