This dairy free coffee cake delivers a cozy cinnamon finish with a tender, bakery-style texture. It is a lovely choice for brunch or an afternoon treat.
Heat the oven to 350°F. Line a 9-inch springform pan with parchment paper and lightly coat the sides with neutral oil.
Stir the flour, brown sugar, cinnamon, and salt for the streusel together. Pour in the melted dairy free butter, mix until large crumbs form, and fold in the chopped pecans.
Whisk the flour, baking powder, baking soda, and salt for the cake in a separate bowl. Beat the softened dairy free butter, granulated sugar, and brown sugar for 3 minutes, then beat in the eggs and vanilla extract.
Mix in the dry ingredients in three additions, alternating with the dairy free sour cream and soy milk. Spread half the thick batter in the prepared pan and scatter with one-third of the streusel.
Cover with the remaining batter and top evenly with the remaining streusel. Bake for 52 to 60 minutes, loosely covering the top with foil if it browns too quickly, until a toothpick comes out clean.
Cool the coffee cake in the pan for 20 minutes, then release the sides and let it cool for at least 45 minutes. Whisk the powdered sugar, soy milk, and vanilla extract into a smooth glaze.
Drizzle the vanilla glaze over the slightly warm cake. Let the glaze set for 15 minutes before serving.
