This Healthy Apple Cake is one for the books! This ridiculously moist, dense, and flavorful cake is made without any flour, butter, or refined sugars! Yet, taste testers didn't even know it was a "healthy" cake! This indulgent-tasting cake is richly spiced with cinnamon, nutmeg, allspice, and cloves.
PREP: Preheat the oven to 350 degrees F (176 degrees C). Line an 8x8-inch baking pan with parchment paper and lightly grease with cooking spray. Set aside for now.
CAKE: Add all the ingredients under "first blend" to a large powerful blender (Blend-tec/Vitamix) and blend until smooth, about 60 seconds. Add in "second blend" ingredients. Blend until smooth and creamy, about 60-90 seconds. Stop and scrape down the sides of the blender as needed. Pour the batter into the prepared pan, using a spatula to scrape out every bit.
BAKE: Smooth the top with the spatula and bake for 35-40 minutes or until cake is lightly browned at edges and set in the middle (toothpick when inserted in the center should come out clean).
DECORATE: Allow cake to fully cool on a wire cooling rack and then cut into pieces. If desired, dust the top with powdered sugar.
Note 1: Blender: You'll need a good, powerful blender (think Blendtec® or Vitamix®) to break down the cashews without over-heating the machine.Note 2: Oats: Although it would seem that any oats would work since they’re getting blended anyways, it’s important to use old-fashioned to ensure you get the right measurement. Both quick and steel-cut oats are smaller, denser, and more compact so measurements would be off and the cake would end up too dry.Note 3: Corn starch: This is an important ingredient since we aren't using flour and need some additional support and thickness.
