Take 2 jars or other small lidded containers. To each one add ½ cup (50 grams) oats, 1 tablespoon chia seeds, 1 tablespoon maple syrup, ½ teaspoon vanilla, a small pinch of salt, ¾ cup plant milk, zest of half a lemon, and 1 tablespoon of lemon juice.
Stir really well, put the lid on tightly and refrigerate overnight or for up to 5 days.
Crumble over the cookie and add a dollop of optional lemon curd before serving. I tend to serve them up in the container they were made in to save on washing up!
