- 2 cups confectioners’ sugar
- 5 tablespoons milk
- 1 teaspoon vanilla extract
Servings: 12–15 | Prep Time: 15 minutes | Cook Time: 30 minutes | Total Time: 45 minutes
Directions
Step 1: Prepare the Batter
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or nonstick spray.
- In a large mixing bowl, whisk together the flour, milk, white sugar, eggs, baking powder, vanilla extract, and salt until smooth and well-combined.
- Stir in the ¼ cup melted butter until incorporated, creating a rich and creamy batter.
- Pour the batter into the prepared baking pan and spread it evenly with a spatula.
Step 2: Make the Cinnamon Swirl
- In a separate bowl, beat together the softened butter, brown sugar, flour, and cinnamon until smooth and creamy.
- Drop spoonfuls of this cinnamon mixture evenly over the batter in the pan.
- Use a butter knife to gently swirl the cinnamon layer into the batter, creating a marble effect. Be careful not to overmix — you want visible ribbons of cinnamon throughout.
Step 3: Bake the Cake
- Bake the cake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center comes out nearly clean (a few moist crumbs are okay!).
- Allow the cake to cool slightly in the pan while you prepare the glaze.
Step 4: Prepare the Glaze
- In a bowl, whisk together the confectioners’ sugar, milk, and vanilla extract until smooth and pourable. If the glaze is too thick, add a touch more milk; if it’s too thin, add a little extra sugar.
Step 5: Glaze and Serve
- Drizzle the glaze generously over the warm cake, letting it sink into the swirls for that gooey, cinnamon-roll effect.
- Slice and serve warm for the ultimate melt-in-your-mouth experience, or let it cool completely for a firmer, glazed finish.
