1-First Step: Get your setup ready by preheating your oven to 350°F. Grease a 9-inch cake pan and line the bottom with parchment paper to ensure your cake slides out perfectly and avoids any sticking drama.

2-Second Step: Whip up the filling by mixing 2 teaspoons ground cinnamon and ¼ cup packed dark brown sugar in a small bowl. Give it a good stir until it’s evenly combined, then set it aside this little mixture is your secret weapon for those dreamy swirls.

3-Third Step: Tackle the cake batter by creaming ½ cup unsalted butter, 1 cup granulated sugar, and 2 tablespoons vegetable oil in a large bowl until it’s fluffy and light, which takes about 3 minutes with your mixer. Beat in the 3 large eggs one at a time, making sure each one is fully incorporated before adding the next for that perfect rise.

4-Fourth Step: Add 1 teaspoon pure vanilla extract and ⅔ cup whole-fat sour cream to the batter mixture, and beat until everything is smoothly blended. This is where the magic happens, creating a base that’s moist and full of flavor mix it just until combined to keep it light.

5-Fifth Step: In a separate bowl, whisk together 1 teaspoon salt, 1 teaspoon ground cinnamon, 2 teaspoons baking powder, and 1 ½ cups all-purpose flour. Gradually add this dry mix to your wet ingredients, stirring gently until just combined overmixing is a no-go, as it can make your cake tough.

6-Sixth Step: Pour the batter into your prepared pan and spread it evenly with a spatula. Now, sprinkle that cinnamon filling over the top for those gorgeous swirls, making sure it’s distributed just right for even flavor in every bite.

7-Seventh Step: For the cream cheese layer, beat 8 ounces cream cheese until it’s smooth and creamy. Add 1 large egg and mix it in, then gradually beat in 2 ¾ cups powdered sugar and 1 teaspoon ground cinnamon until the mixture is silky spread this over the batter for that ooey-gooey topper.

8-Eighth Step: Pop the pan into your preheated oven and bake for 40 45 minutes. You’re looking for golden edges and a center that’s still a bit jiggly it’s done when a toothpick comes out with moist crumbs, not wet batter, so keep an eye on it to avoid overbaking.

9-Ninth Step: Once out of the oven, let the cake cool in the pan for 10 15 minutes at room temperature. Then, transfer it to the fridge and chill for at least 2 hours to let it set properly this step is key for the perfect texture, so don’t skip it!
