Ingredients
Method
- Preheat oven to 350°F (175°C). Grease an 8-inch round pan and line with parchment. Mix the oat milk and vinegar in a large bowl; let stand 5 minutes. Whisk in oil, sugar, eggs, and vanilla until glossy.
- In another bowl, whisk together the flour, baking powder, baking soda, and salt for 30 seconds.
- Pour the dry ingredients into the wet and fold gently with a spatula until no dry flour remains. Do not overmix.
- Scrape the batter into the prepared pan, smooth the top, and bake for 30 to 35 minutes until a toothpick comes out with moist crumbs. Cool in the pan 10 minutes, then invert onto a rack, remove parchment, and cool completely.
- Whisk the powder sugar, 2 tablespoons non-dairy milk, and vanilla for the glaze. Add up to 1 more tablespoon of milk for a pourable consistency. Pour over the cooled cake, nudge into a thin layer, and let set briefly. Slice and serve.
Notes
The vinegar-milk mixture needs a full 5 minutes to thicken, so start with that step. If you do not have parchment paper, grease the pan generously and dust it with a little extra gluten-free flour. The cake tastes even better the next day, so it is great for making ahead.
