Easy White Chocolate Lava Mug Cake in a Microwave

A quick and easy White Chocolate Lava Mug Cake made in a Microwave. This healthy chocolate lava cake has a white chocolate center made with cashew butter and chocolate chips and is perfect for an instant gooey mug cake dessert. No oven or baking needed!

Stating a fact here: making a molten chocolate lava cake in a microwave is not as easy as I thought.

I’ve tried and test tested healthy mug cakes before and have that part nailed down - the light airy and fluffy texture. But getting a gooey molten chocolate center in a mug cake does not work the same unless you add a ton of the ‘bad ingredients’.

After a lot of experimenting, I found the key for this recipe: Cashew butter (or another nut/seed butter) stirred with a bit of coconut oil + chocolate chips.

So now the runny melty filling remains in place, instead of dropping to the bottom or drying out.

    Is there a way to make this without a microwave. I'm opposed to using them. Thanks, it looks scrumptious!! I appreciate your culinary research on our behalf.

      Hi Sam! This really means a lot!

      I haven't tried this myself, but I think 8-10 minutes in the oven at 350°F should do it. I really would love to know how it turns out!
