Preheat the oven to 350°F and grease a loaf pan with olive oil.
Add the lemon juice to the almond milk and set aside.
Whisk together the maple syrup, olive oil, eggs, and vanilla in a large bowl. Add the almond milk mixture and whisk again.
Add the dry ingredients and stir with a spatula until thoroughly combined, making sure there are no lumps of flour.
Pour the batter into the greased pan and bake for 25-35 minutes, or until a toothpick comes out clean or with just a few tiny crumbs attached. Cool for ten minutes in the pan, then use a butter knife to loosen the edges of the cake and transfer it to a rack to cool completely.
Slice the cake thickly and grill for 1-2 minutes per side. Serve warm with lemon curd and fresh berries.
