Carrot Cake Bars with Brown Butter Cream Cheese Frosting

Every year around this time, I get a craving for really good carrot cake. In the past years I’ve made Carrot Bundt Cake, Healthy Carrot Cake Bars, and classic Carrot Cake with Cream Cheese Frosting. This year, I’m going back to the bars, and I topped it with one of the best frostings I’ve ever had – brown butter cream cheese frosting.

While the carrot cake bars in this recipe is tender, moist, and perfectly spiced, I think the star of the show is that frosting. I mean, how can you go wrong with brown butter and cream cheese?!

Ingredients in Carrot Cake Bars

Melted Butter – a lot of carrot cake recipes call for oil, but I love the buttery flavor that comes from using melted butter.

Sugar – I had intended to use a combination of brown sugar and white sugar but my brown sugar was hard as a rock.



Grated Carrots – 2 whole cups! I love using my food processor to easily grate/shred carrots.

Flour, Baking Soda, Baking Powder, Salt

Ground Cinnamon, Nutmeg, and Cloves – for that special carrot cake flavor

Brown Butter, Cream Cheese, Powdered Sugar, and Milk – for the frosting!

How to Make Carrot Cake Bars

This carrot cake bar recipe is simple to whip up. Simply whisk together the butter, sugar, egg and egg yolk, vanilla, and carrots for the wet ingredients. Next, add in the dry ingredients and stir with a spatula until combined. Easy!

The bars get baked in a 9×13″ pan and while they are baking, you can make the frosting.

With the brown butter, you’ll want to do this while the bars are baking because you will melt/brown the butter and then it needs to cool off. This will make it easier to combine with the cream cheese. I stuck mine in the refrigerator for about 15 minutes so it was cooled off but not completely hardened.

Then you just beat the brown butter, cream cheese, powdered sugar, and a splash of milk for the frosting. And try not to eat the whole bowl – it’s hard not to!!

Make the Brown Butter Cream Cheese Frosting

  1. This is exactly how I love my carrot cake too! No nuts or raisins. Some of my favorite recipes of yours are the pumpkin bars and carrot cake bars, because not only is the cake itself delicious, the frosting is SO delicious. Cream cheese frosting is so awesome… Thank you!
