05 - 1 1/2 cups all-purpose flour
06 - 1 tsp baking powder
07 - 1/4 tsp baking soda
08 - 1/4 tsp 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 tsp vanilla extract
15 - 1 tbsp 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 - Combine cranberries, sugar, orange juice, and zest in a saucepan. Simmer over medium heat for 8 to 10 minutes, stirring occasionally, until cranberries burst and mixture thickens. Remove from heat and cool slightly before pureeing or mashing until smooth.
03 - In a bowl, whisk together flour, baking powder, baking soda, and salt.
04 - Beat butter and sugar in a large bowl until light and fluffy, approximately 2 to 3 minutes. Add eggs one at a time, mixing well after each addition. Incorporate sour cream, orange juice, vanilla extract, and orange zest until fully combined.
05 - Gradually add the dry ingredients into the wet mixture, stirring gently until just incorporated to avoid overmixing.
06 - Pour half of the batter into the prepared pan and smooth the top. Spoon cranberry mixture over batter, then add the remaining batter. Dollop remaining cranberry mixture on top.
07 - Use a skewer or knife to gently swirl the cranberry and orange batters together in a spiral pattern without overmixing.
08 - Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
09 - Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
10 - Dust with powdered sugar and garnish with additional orange zest or sugared cranberries before serving.
