Brownies will walnuts on top may be my new favorite way to enjoy fudgy keto brownies. Tender on the outside, studded with crunchy walnuts and moist and gooey on the inside…these satisfy any chocolate fix out there.

Unlike traditional walnut chocolate brownies, these are a little different. Not only are they grain-free, keto and low carb, they are also completely paleo and gluten-free. I’ve also included some vegan options, and of course, they are dairy-free!

How to make walnut brownies

I often get asked how to add walnuts to brownies or brownie mix, and it is as easy as adding chocolate chip or other mix-ins!

The Ingredients

Cocoa Powder. A good quality cocoa powder provides an extra richness and delicious chocolate flavor. For a darker taste, use dark cocoa powder.
Zero calorie sugar. I used a zero-calorie sweetener, erythritol, to ensure these brownies are sugar-free, keto-friendly and low carb.
Tapioca Flour OR Corn Starch. This is needed to help hold the brownies together, as there is no flour in it. You can substitute this for arrowroot if needed. For those following a strict ketogenic diet, the amount of cornstarch distributed amongst each brownie is minimal.
Chocolate chips. The chocolate chips are needed to be melted with the coconut oil, before adding it to all the other ingredients. Furthermore, you can add an extra 1/2 cup of chocolate chips into the brownie batter prior to baking.
Eggs. You MUST whisk the eggs before adding the other ingredients. This ensures evenly baked brownies and ensures they cook and rise correctly. Room temperature eggs are preferred over refrigerated ones.
Butter. Room temperature butter is best, as it will melt much better with the chocolate. You CAN substitute this for coconut oil.
Walnuts. Unsalted, raw walnuts are best. Be sure to roughly chop them to ensure they are evenly distributed.

The Directions

Preheat the oven to 180C/350F. Line a square pan with parchment paper and set aside.
In a small bowl, sift the cocoa powder and cornstarch, to avoid any clumps.
In a small saucepan, combine your butter with chocolate chips and on low heat, warm up until melted. Whisk together until combined and glossy. Remove from the heat.
Stir in the sugar, then add in the eggs, one at a time. Add the rest of the ingredients and mix very well, until you are left with a thick, glossy mixture. Fold through your walnuts.
Transfer your brownie batter into the square pan and bake for 26-28 minutes, or until a skewer comes out ‘just’ clean from the center.
Remove brownies from the oven and allow to cool in the pan completely, before slicing into pieces.

Recipe Substitutions and Dietary Swaps

Vegan Walnut Brownies. I haven’t tried replacing the eggs, but in other brownie recipes have tried egg replacers and flax eggs. If you try one of these out, I’d love to hear how it worked!
Paleo Walnut Brownies. Replace the keto chocolate chips with dairy-free chocolate chips.
Zero Calorie Sweetener. If you don’t follow a sugar-free diet, you can use any granulated sweetener of choice, like brown sugar, coconut palm sugar, and even white sugar.
Dark Chocolate Walnut Brownies. Replace the cocoa powder with black cocoa powder or dark cocoa powder.
Double Chocolate Flourless Brownies. Fold through 1/4 cup of chocolate chips to the batter.

How to store and reheat fudgy walnut brownies

To Store. Fudgy Walnut brownies are best stored in the fridge, to avoid them spoiling and to ensure freshness. Place brownies in a sealable container and place in the fridge for up to 7 days.
To Freeze. These brownies are freezer friendly and can be stored in the freezer. Individually wrap brownies in parchment paper and place them in a ziplock bag or shallow container. Brownies will keep fresh for up to 6 months.
To Reheat. To reheat walnut brownies, allow thawing at room temperature or in the fridge overnight. You are also able to reheat in the microwave to enjoy it warm, but only once it has been thawed.
