Easy Cinnamon Roll Coffee Cake

Preheat your oven to 350°F (175°C).
2. Make the Cake:

In a large bowl, combine melted butter, eggs, sugar, flour, vanilla, baking powder, salt, and milk. Mix until well combined.
3. Pour the Batter:

Pour the cake batter into a greased 9×13-inch pan.
4. Make the Topping:

In a small bowl, mix together melted butter, brown sugar, flour, and cinnamon. Stir until smooth.
5. Add the Topping:

Spread the cinnamon topping evenly over the batter. Use a knife to gently swirl the topping into the batter for a marbled effect.
6. Bake:

Bake at 350°F (175°C) for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Make the Glaze:

In a small bowl, whisk together powdered sugar, milk, and vanilla until smooth and the consistency of pancake syrup.
8. Drizzle the Glaze:

While the cake is still warm, drizzle the glaze over the top. The glaze will set into a thicker consistency as it cools.
