# What You’ll Need:

01 - 1 1/2 cups fresh or frozen cranberries
02 - 1/2 cup granulated sugar
03 - 2 tablespoons orange juice
04 - 1 teaspoon finely grated orange zest
→ Orange Cake Batter
05 - 1 1/2 cups all-purpose flour
06 - 1 teaspoon baking powder
07 - 1/4 teaspoon baking soda
08 - 1/4 teaspoon salt
09 - 1/2 cup unsalted butter, softened
10 - 3/4 cup granulated sugar
11 - 2 large eggs, room temperature
12 - 1/2 cup sour cream
13 - 1/4 cup fresh orange juice
14 - 1 teaspoon vanilla extract
15 - 1 tablespoon finely grated orange zest
→ Decoration (Optional)
16 - 1/4 cup powdered sugar
17 - Orange zest or sugared cranberries
# Directions:
01 - Preheat the oven to 350°F. Grease and line the bottom of a 9-inch round cake pan with parchment paper.
02 - In a small saucepan, combine cranberries, sugar, orange juice, and zest. Simmer over medium heat for 8 to 10 minutes, stirring occasionally, until cranberries burst and the mixture thickens. Remove from heat and cool slightly. Puree or mash until smooth.
03 - In a bowl, whisk together flour, baking powder, baking soda, and salt until evenly blended.
04 - In a large bowl, beat the butter and sugar with an electric mixer until light and fluffy, about 2 to 3 minutes. Add eggs one at a time, mixing thoroughly after each addition.
05 - Mix in sour cream, orange juice, vanilla extract, and orange zest until combined.
06 - Gradually add dry ingredients to the wet mixture, stirring just until combined. Avoid overmixing.
07 - Pour half of the cake batter into the prepared pan and smooth the surface. Spoon half of the cranberry mixture over batter. Add remaining batter, then dollop remaining cranberry mixture on top.
08 - Use a skewer or knife to gently swirl the cranberry and orange batters together in a spiral pattern, taking care not to overmix.
09 - Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
10 - Allow cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Optional: Dust with powdered sugar and garnish with orange zest or sugared cranberries before serving.
