# What You Need:
→ Cranberry Swirl
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 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 mixture thickens. Remove from heat and cool briefly. Puree with a blender or mash until smooth.
03 - Whisk together flour, baking powder, baking soda, and salt in a bowl.
04 - Beat butter and sugar in a large bowl until light and fluffy, about 2 to 3 minutes. Add eggs one at a time, mixing thoroughly after each. Incorporate sour cream, orange juice, vanilla, and orange zest until evenly blended.
05 - Gradually add dry ingredients to the wet mixture, mixing just until incorporated. Avoid overmixing.
06 - Pour half the batter into the prepared pan and smooth the surface. Spoon cranberry mixture over batter. Add remaining batter, then dollop remaining cranberry mixture on top. Using a skewer or knife, gently swirl batters together in a spiral pattern without overmixing.
07 - Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
08 - Allow cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
09 - Dust with powdered sugar and garnish with additional orange zest or sugared cranberries before serving.
