Making Easy Gluten Free Cinnamon Roll Cake is as simple as following these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish for easy removal.
2. Combine Dry Ingredients: In a large bowl, whisk together the gluten-free flour, granulated sugar, baking powder, and ground cinnamon.
3. Add Wet Ingredients: Pour in the milk, melted butter (or coconut oil), and vanilla extract. Mix until everything is well combined and smooth.
4. Pour Batter: Pour the batter into the prepared baking dish, leveling it out with a spatula.
5. Create Cinnamon Swirl: In a separate bowl, mix a bit more cinnamon and sugar (about 1 tablespoon each) and sprinkle it on top of the batter to create a cinnamon swirl. Use a knife to gently swirl it into the batter.
6. Bake: Place the baking dish in the oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool: Remove the cake from the oven and let it cool in the pan for about 10-15 minutes before transferring it to a wire rack to cool completely.
8. Prepare the Glaze: In a small bowl, mix powdered sugar with a splash of milk to create a simple glaze. Adjust the consistency as desired.
9. Glaze the Cake: Drizzle the glaze over the cooled cake, allowing it to soak in for added moistness and flavor.
