Preheat the oven to 370℉. Prepare an 8-inch round cake pan; you can spray the base and sides with an oil spray, or line with parchment paper.
Peel naseberry, remove the seeds and puree or mash with a fork. Set aside.
In a medium bowl, mix non-dairy milk, coconut oil, ground flaxseeds, and vanilla, and set aside.
In a large bowl, add gluten-free flour, almond flour, sugar, baking powder, cinnamon, ginger, and salt, and stir to combine.
Add the milk mixture to the flour mixture and combine until the batter is smooth, then fold in the naseberry. The batter should look like a thick pancake batter.
Scoop the batter into the prepared pan and smooth the top with a spatula.
Bake for 60 minutes, or until a fork inserted in the center comes out clean.
Remove the cake from the oven and allow it to sit for 5 minutes in the pan. Transfer to a cooling rack and allow to cool completely before adding the cream cheese frosting.
