Indulge in this gorgeous one-layer gluten free carrot cake that's packed with juicy shredded carrots and crunchy walnuts and topped with a thick swath of tangy cream cheese frosting.
Grease a 9-inch baking round and line it with a circle of parchment paper.
In a medium bowl, whisk together the oat flour, baking powder, spices, and salt.
In a large bowl, whisk together the brown sugar and oil. Whisk in the yogurt for about 1 minute until the mixture is thick and slightly lighter in color. Whisk in the eggs one at a time, then whisk in the vanilla.
Stir the dry mix into the wet mix, then fold in the carrots and walnuts. Pour the batter into the prepared pan.
Preheat the oven to 350℉ and let the batter rest while the oven heats. Then bake the cake for 40-45 minutes until a tester comes out clean, the top is set, and the sides are slightly coming away from the edges of the pan. Remove the cake from the oven and cool for 15 minutes in the pan on a wire rack, then turn out to cool completely.
When the cake is cool, make the frosting: In a large bowl, cream the softened cream cheese and butter together on medium speed using an electric mixer for 2-3 minutes until creamy and combined. Beat in the powdered sugar until thick and combined.
