I made this tonight. It's delish but I found that it needed almost 2 1/2 minutes in my microwave which is a fairly hot microwave. Maybe the egg I used was too large or I might try only two tablespoons of almond milk next time. Thanks for sharing your recipe!

So glad to hear you liked the recipe! Thank you for taking the time to leave your feedback. Sorry to hear that the timing didn't quite work out for you, but I'm glad you were able to adjust it to your microwave's setting. Egg and milk can definitely affect the timing. Thanks again for the comment. :)
