Equipment
Method
- Preheat oven to 350°F and grease a 9×13-inch baking dish with cooking spray.
- In a large bowl, mix flour, granulated sugar, baking powder, eggs, vanilla, and milk until just combined.
- Slowly pour in the melted butter while mixing. Do not overmix. Pour batter into prepared dish.
- In a separate bowl, combine softened butter, brown sugar, flour, and cinnamon for the filling. Mix until smooth.
- Drop cinnamon mixture by spoonfuls over the batter. Use a knife to swirl through the batter.
- Bake for 35–40 minutes, until a knife inserted comes out clean.
- While the cake is baking, whisk together powdered sugar, milk, and vanilla for the glaze.
- Once the cake is done and slightly cooled, pour glaze evenly over the top. Serve warm or at room temp.
Notes
Serve warm for extra gooey goodness or at room temperature for cleaner slices. If you're short on butter, you can reduce the cinnamon filling to one stick without losing too much flavor.
