1️⃣ Make the Vanilla Cake:

• Preheat your oven to 350°F.
• In a large bowl, mix cake mix, eggs, oil, buttermilk, and vanilla until smooth. Set aside.

2️⃣ Create the Cinnamon Swirl:

• In a small bowl, combine brown sugar, flour, cinnamon, and melted butter. Stir until mixed.

3️⃣ Assemble and Bake:

• Spray a Bundt pan liberally with nonstick cooking spray.
• Pour half the cake batter into the pan. Spoon half the cinnamon swirl mixture on top. Swirl it into the batter with a toothpick.
• Add the remaining cake batter, then top with the rest of the cinnamon swirl mixture. Swirl again.
• Bake for 40-45 minutes, or until a toothpick inserted comes out with crumbs (but no raw batter). Let cool for 15 minutes in the pan, then invert onto a serving plate.

4️⃣ Make the Cream Cheese Glaze:

• Beat cream cheese and butter until smooth. Add vanilla and powdered sugar, mixing until frosting consistency. Add a little milk if needed.
• Use a piping bag (or a plastic bag with the corner snipped) to drizzle the glaze in a zigzag over the cooled cake.

5️⃣ Add the Cinnamon Sugar Topping:

• While the glaze is still wet, sprinkle the cinnamon-sugar mixture on top.

6️⃣ Serve and Enjoy:

• Best served fresh or store in the fridge for up to 4 days. You can also freeze it for up to 3 months!
