FAQs

Can I use gluten-free flour instead of all-purpose flour?

Yes, you can substitute gluten-free flour blends 1:1, but ensure the blend contains a binding agent for best results.

What if I don’t have a microwave?

You can bake the batter in a small oven-safe ramekin at 350°F (175°C) for about 10-12 minutes, or until set but still soft inside.
