Just Beet It Vegan Gluten-Free Red Velvet Cake

Directions

1. 1
   Preheat the oven to 350F. Line an 8x8-inch square pan with parchment paper (double-check your pan size, because 9x9-inch wont work for this recipe).
2. 2
   Add the rolled oats, coconut sugar, cacao powder, baking powder, and sea salt to a food processor fitted with the S-blade. Process for 4 minutes, or until the oats are finely ground and the texture of the mixture resembles flour.
3. 3
   Transfer the flour mixture to a large mixing bowl and set aside.
4. 4
   Add the beets to the empty food processor and pulse 30 to 45 times, or until very finely grated, stopping to scrape down the sides as needed. The texture should resemble cous cous. Then, add the coconut oil, almond butter, maple syrup, and vanilla, and process for 30 seconds, or until nearly pured, stopping to scrape down the sides as needed. (The texture should resemble watery applesauce.)
5. 5
   Add the pured beet mixture to the oat mixture, and stir until incorporated and no flour patches remain in the bottom of the bowl. Do not over-mix. The mixture should resemble a very thick, somewhat fluffy batter thats spoon-able but not easily poured.Spoon the batter into the lined pan and use a spatula to gently smooth out toward the edges in an even layer. At first it will seem like there isnt enough but just keep smoothing.
6. 6
   Bake for 18 to 24 minutes, or until the surface is crackled and a toothpick inserted into the center comes out mostly clean with several very moist crumbs clumped together at the tip. Do not over-bake. In fact, err on the side of slightly under-baking if you're unsure.
7. 7
   Transfer the pan to an oven-safe cooling rack and cool completely.Get started on the icing as soon as the cake is in the oven.
8. 8
   Add the soaked cashews and 1/2 cup of the almond milk to a high-speed blender, and blend on high until smooth, stopping to scrape down the sides as often as needed. Only if absolutely needed, add the remaining almond milk (up to 1/4 cup), 1 tablespoon at a time, as needed to blend the cashews until smooth. The texture should resemble thick cream.
9. 9
   Add the remaining icing ingredients and blend for 30 seconds, or until smooth, stopping to scrape down the sides as needed.Scoop the icing into a shallow bowl and chill in the freezer for at least 15 minutes to thicken slightly. If you have the time, I recommend chilling for up to 1 hour and vigorously whisking every 10 to 15 minutes (to prevent freezing) until thick and fluffy.Once the cake is completely cool, smooth as much of the icing as desired*** over the surface. I typically use about 3/4 of the batch on top and reserve the remaining icing for those who want an extra slather while enjoying a piece of cake (my hand is raised).
10. 10
    Sprinkle with the toppings (if using).If needed, freeze for 30 minutes to set the icing.Once the icing is set to desired thickness, grasp the edges of the parchment paper to gently lift the cake from the pan, and use a sharp knife to slice.
11. 11
    Serve and return any leftover cake to the pan. Loosely cover the pan with foil, and store in the refrigerator**** for up to 3 days.
