Step 1: Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan or line it with parchment paper.
Step 2: In a medium bowl, whisk together the flour, baking powder, baking soda, 2 tsp cinnamon, nutmeg, and salt to ensure even distribution for the sticky maple carrot cake with cinnamon drizzle base.
Step 3: In a separate large bowl, beat the eggs, 1 cup maple syrup, oil, and vanilla extract until well combined and slightly frothy.
Step 4: Gradually add the dry ingredients to the wet ingredients, stirring gently with a spatula until just combined. Avoid overmixing to keep the sticky maple carrot cake with cinnamon drizzle tender.
Step 5: Fold in the freshly grated carrots until evenly distributed throughout the batter.
Step 6: Pour the batter into the prepared pan and bake for 40-45 minutes, or until a toothpick inserted into the center of the sticky maple carrot cake with cinnamon drizzle comes out clean.
Step 7: While the cake cools slightly, whisk together the powdered sugar, 1 tbsp maple syrup, 1/2 tsp cinnamon, and milk in a small bowl until smooth.
Step 8: Remove the cake from the pan and, while still slightly warm, pour the cinnamon drizzle over the top, allowing it to soak into the sticky maple carrot cake with cinnamon drizzle.
