blackberry miso cornmeal cake - TK

Ingredients

• 1 box cornbread mix (such as Wholesome or Jiffy)
• 1 egg
• 1/3 cup milk (I use almond or coconut milk)
• 1 pint blackberries
• 1 tablespoon agave or honey
• 1 tablespoon miso paste (light/white)
• 1 13.5 ounce can full fat coconut milk that has been refrigerated*
• 2 tablespoons reserved blackberry miso mixture
• 1 tablespoon sugar (optional) - I don't think the topping needs it, but use at your discretion if you like things sweeter
• 1 teaspoon vanilla powder (or vanilla/vanilla paste)
• 1/4 teaspoon cream of tartar (optional but helps to stabilize whipped topping)
