Plain flour or self rising?
All Purpose
I stopped adding up the calories on this when I got to over 600. Yikes! You could have something much more decadent and satisfying if you’re willing to eat that many calories. Definitely not a little sweet indulgence before bed.
Do you think this recipe could be done using a toaster oven rather than a microwave? If so, how long/what temp do you think?
Not sure that would work, could try.
What size mug would you recommend and should it have flat sides, not tapered? I’m super excited to try this! Thanks so much!
I put a link to a mug in the post just now, 12 oz. or larger. Just don’t use a small coffee cup because it will rise and bubble over.
This is the second time I’ve made this, amazing!! Just can’t remember, is a Tablespoon or teaspoon of peanut butter? The ingredients list says 1 t., but the directions say 1 T.
Sorry! Was transitioning to a new recipe plugin and it transferred it weird. It is 1 tbsp., fixed it! So glad you love it too!
Probably the best mug cake I’ve tried so far (and I’ve tried a heaping handful)! Also worked with gluten free flour as a sub for regular flour 😀
Thanks!
SO glad you loved it!!
I started making this treat whenever I get chocolate cravings and it’s so easy and yummy! I also love that it is dairy free. Thanks so much for sharing!
OH yeah, so glad!
