How do I know when lava cakes are done?
Look for set edges and a thin brownie-like top that looks just set. If you gently tap the ramekin, the center should jiggle slightly. If the whole thing sloshes, give it another minute. Another clue: the edges should look set about 1/2 inch in, while the center still looks a little soft and glossy.
Why did my lava cakes not ooze?
Most likely they baked a little too long or your oven runs hot. Next time, pull them 1 to 2 minutes earlier. Also make sure you are using the ramekin size you think you are. This recipe is written for 4-ounce ramekins; larger ramekins need a different timing.
What if I only have 6-ounce ramekins?
Totally fine. You will usually get 3 cakes instead of 4, and you will want a slightly longer bake: start checking at 11 minutes and expect about 11 to 13 minutes, depending on your oven and how cold your batter is.
Can I use chocolate chips?
Yes, but use bittersweet or dark chips for best flavor. Chips often include stabilizers, so the texture can be slightly less silky than chopped chocolate bars. Still delicious.
Can I make this gluten free?
You can usually swap the all-purpose flour for a 1:1 gluten-free baking blend. The amount of flour is small, so it is a friendly recipe for that kind of substitution.
Do I have to flip them out of the ramekins?
Nope. You can serve them right in the ramekins. If you are flipping them, let them rest 1 minute, run a thin knife around the edge, and invert onto a plate with confidence. If one sticks, no problem. Serve it in the ramekin and call it rustic.
Are lava cakes safe to eat?
The gooey center comes from a slightly underbaked batter made with eggs. If you are pregnant, immunocompromised, elderly, or serving very young kids, you may want to bake until the center is fully set (it will be more like a very good chocolate cake) or use pasteurized eggs.
