Ingredients

Dry Ingredients

Wet Ingredients

  • 4 large eggs
  • 1/4 cup walnut oil (or melted butter)
  • 1 teaspoon vanilla
  • 1 teaspoon stevia glycerite
  • 1/2 cup buttermilk (or full-fat coconut milk, or heavy cream)

Chocolate Ganache Glaze

Instructions

Preparation

  • Preheat oven to 325 degrees F and position rack to the middle of the oven. Trace the bottom of an 8 x 2 inch cake pan on a sheet of waxed paper or parchment. Cut out the circle. Spray the cake pan with baking spray and line the bottom of the pan with the parchment circle. Weigh walnuts and process in a food processor with the sweetener until a finely ground. 

Proceedure

  • Measure the dry cake ingredients (including the ground walnuts) in a medium bowl and stir thoroughly with a large whisk to combine. In another bowl, add the wet ingredients and beat with a hand mixer. Pour the wet ingredients into the dry and mix until all of the ingredients are completely incorporated. 
  • Spoon the batter into the cake pan and gently tap it on the counter 2-3 times to dislodge any big air bubbles. Bake for approximately 30-40 minutes or until the cake still sounds moist when gently pressed with your finger and a toothpick inserted into the middle comes out clean. Do not over bake!
  • Remove the Chocolate Walnut Cake from the oven and cover with a clean tea towel. Let the cake cool completely. Then wrap in plastic wrap until ready to top with ganache. Make sure the cake is at room temperature before topping with the ganache.

Chocolate Ganache Glaze

  • Finely chop the chocolate and place it in a small microwaveable bowl with the heavy cream and butter. Cover with waxed paper and microwave for 30 seconds. Let stand for 1 minute, then gently whisk to combine. The ganache should be thick and glossy. Use right away.
  • Pour the chocolate ganache into the middle of the cake and spread with a spatula or knife, encouraging it to drip over the side. Decorate with optional walnut halves or walnut pieces if you wish, while the ganache is still soft. Cut and serve after the ganache has hardened (it will still be fairly soft but not runny). 
  • Store in the refrigerator or on the counter. If refrigerated, let it come to room temperature for 30 minutes before enjoying. Serves 12.

Notes

Walnut oil is a pricey item. Get a good quality oil that is in a dark bottle. It will last a few years in the refrigerator. It's good in salad dressings and baked goods. I have had mine for 3 years and it's still delicious.
