Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish or line it with parchment paper.
Prepare the Cake Batter:
In a large mixing bowl, combine the oat flour, almond flour, coconut sugar, baking powder, baking soda, salt, and ground cinnamon. Mix well.
Wet Ingredients:
In another bowl, whisk together the coconut milk (or coconut yogurt), melted coconut oil, maple syrup, vanilla extract, and eggs until smooth.
Combine Ingredients:
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix.
Prepare the Cinnamon Swirl:
In a small bowl, combine the coconut sugar, ground cinnamon, and melted coconut oil until you have a thick, crumbly mixture.
Assemble the Cake:
Pour the cake batter into the prepared baking dish. Sprinkle the cinnamon swirl mixture evenly over the batter. Then use a knife to gently swirl it into the batter.
Bake:
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan.
Prepare the Cream Cheese Glaze:
In a medium bowl, whisk together the softened dairy-free cream cheese, powdered sugar, almond milk, and vanilla extract until smooth.
Glaze the Cake:
Once the cake has cooled, drizzle the cream cheese glaze over the top. Use a spatula or the back of a spoon to spread it evenly.
Serve and Enjoy:
Cut the cake into squares and serve. Enjoy the comforting flavors of cinnamon roll in every bite!
