Add everything to a blender and blitz until smooth and creamy, with no oat bits remaining and the strawberries fully worked in, turning everything a gorgeous soft pink.
Preheat your waffle iron while the batter rests for a few minutes. Lightly grease it if needed, even on a nonstick model, as this batter is delicate and deserves a little help releasing.
Pour the batter into the iron and cook until deeply golden and set. Resist the urge to peek too early - these need a little extra time compared to a classic waffle, since there's no flour here to help them firm up quickly.
Serve them immediately, with whatever your morning is asking for; a dollop of yogurt, a scatter of fresh berries, a drizzle of honey or maple syrup. Eat right away, while they're warm and golden at the edges. Say thank you and enjoy!
