    Dear Cassey!
    I’d like to try this recipe, but I am alergetic to nuts. I haven’t find yet a replacement for almond flour that gives a similar texture! Would you have any suggestion?

        sorry…flour 🙂

    2. Sr says:

      Have you tried flax seed meal? That has a similar texture. Maybe mixed with buckwheat flour?

    I just came across your 14 day workout program and meal plan. I have a question about the snacks. I see 2 snacks per day. Do you eat the 2 snacks or you choose one per day?

    1. Chaye says:

      The plan is for both snack with roughly 2,000 calories a day

    2. Whitney says:

      Wanted to jump in and say, I’ve been eating both snacks! I think that’s how she set it up:)

  6. This is the first mug cake that I have ever come across that tastes absolutely amazing! I’m a homemaker and bake quite often. I’m always looking for new recipes. I give this peanut butter mug cake a 5 out of five. Truly delicious! I can’t get over how fluffy it is. Absolute mug cake perfection. Thank you for sharing this recipe.

    Dear Cassy,
    I am a young teen and I find myself constantly comparing my body, workouts, and diets to that of adults (ex: my mom, you, other celebrities). I know this is not good because all of these people are in very different stages of life than me. I found myself for a while restricting breads and sugar, which was extremely bad for my mental health. I don’t know how to stop these comparisons. I love you and I want to go back to trying to be my best self and not anyone else’s best self. Thank you for your amazing videos and posts! You are so motivational and supportive. Sincerely, Wants to Stop comparing

      *diet- as in my food portions and meals (I am not following a diet plan other than taking ideas from your hot girl summer sculpt which I love by the way)

  8. Magdalyn says:

    Hey Cassey, I made this for my mom yesterday and she loved it!!! I used vanilla yogurt instead of coconut yogurt and it was delicious!!😋

  9. Hi Cassie! What kind of flour/milk alternatives would you recommend if you’re allergic to tree nuts? I’m not allergic to peanuts (thankfully) and would love to try this recipe!

    1. Magdalyn says:

      Hi Melissa!! I used oat flour. And I’m pretty sure you can use whole milk. Hope this helps!!

    2. Magdalyn says:

      Hi Melissa!! I used oat flour instead of almond flour and whole milk instead of almond milk. Hope this helps you!!

  10. Allisha says:

    I am going to have to definitely try this! And post it on Instagram! I am currently participating in the 2 week summer sculpt and am finding it difficult not to eat bad treats! On top of that, a lot of stressful stuff has happened including a job loss, and I also use sweet snacks as a comfort mechanism. Can I cheat and use unsweetened frozen coconut yoghurt with it? LOL!

    made this, and it turned out like some sort of chewy peanut buttery scrambled eggs. knowing my glowing expertise in the kitchen, i probably made it wrong, but it wasn’t my fave
