Orange-Walnut Cake

This dessert makes guests happy in many ways. It’s loaded with vitamins B12 (from the yogurt) and C (orange juice), folate (OJ, again), and omega-3 fatty acids (walnuts) — all nutrients shown to boost your mood.

Ingredients

Serves 8

• 1/2 cup olive oil, plus more for the pan
• 1 1/2 cups all-purpose flour (spooned and leveled), plus more for pan
• 1 cup walnuts
• 1 tablespoon freshly grated orange zest, plus more for garnish
• 2 teaspoons baking powder
• 1 teaspoon salt
• 2 large eggs
• 1 cup packed light-brown sugar
• 3/4 cup fresh orange juice
• Confectioners’ sugar for garnish
• 1 cup low-fat Greek yogurt
• 2 tablespoons confectioners’ sugar

Directions

1. Preheat oven to 375 degrees. Brush cake pan with oil, line bottom with parchment; oil and flour parchment and pan. Place walnuts in a food processor and pulse until finely ground (be careful not to overprocess); set aside.
2. In a large bowl, whisk together orange zest, flour, baking powder, salt, and ground walnuts. Make a well in the center of the flour mixture and stir in eggs, brown sugar, orange juice, and oil until just moistened; do not overmix.
3. Pour batter into prepared pan and bake until a toothpick inserted in the center of the cake comes out clean, 40 to 45 minutes. Let cool in pan for 10 minutes; transfer to a cooling rack to cool completely.
4. In a small bowl, stir together yogurt and confectioners’ sugar. Before serving, dust the cake with confectioners’ sugar. Serve with sweet yogurt garnished with orange zest, if desired.
