First, roughly chop the nuts, about 8 of each, add the salt, softened butter, and honey, and continue chopping a little to combine the ingredients. You can add more honey or butter if you like. The pieces should be neither too large nor too small. Set aside.

In a bowl, beat the eggs, sugar, yogurt, oil, and orange zest for about 10 minutes.

Sift the flour and baking powder, mixing gently in a folding motion.

Grease and flour a loaf pan, or you can use parchment paper, whichever you prefer. Pour in our batter and add the nut and honey mixture in the center. Sprinkle with sugar and bake at 340°F (170°C) for about 15 minutes, or until a toothpick inserted into the cake comes out clean, indicating it's done.
