  1. BEST KEY LIME PIE EVER! I have to admit, though that after making the sweetened condensed milk recipe I could have just stopped and eaten the whole 14 oz with a spoon- it’s THAT delicious!!

    • Oh, Jennifer!! You are too sweet! Your comment has made my week 🙂

  2. When making the whipped topping do I literally just whip, the heavy whipping cream in my stand mixer?

    Reply

    • Hi Kelly,

      You sure do!

  3. My pie had AMAZING flavor but it wasn’t all too creamy. It had. Gritty texture to it. I did make the condensed milk with powdered swerve…that’s the only difference i made :/

    Reply

    • Hi Beth,

      It could be the powdered swerve that caused it, I have only ever made the condensed milk with granulated sweetener. I would suggest sticking with granulated sweetener for the sweetened condensed milk for next time 🙂

  4. hi! i am planning on making this tomorrow but my local stores didn’t have almond meal or flax meal – so i just bought almond flour. would the crust work with almond flour? if so should i adjust the ingredient amounts? thanks soooo much

    Reply

    • Hi Drew,

      I don’t recommend making the crust on almond flour alone as it needs the flax meal to help it come together. You could try using the recipe for the crust in our Quiche Lorraine recipe, but leave out the salt and pepper, and add 1 tbsp of sweetener.

      I hope that helps.

  5. This might be a stupid question- but when it calls for 7 ounces of Almond meal- is that like 7 fluid ounces (as in I should measure in a measure cup) or 7 ounces in weight?

    Thank you!!

    Reply

    • Hi Kim,

      7 ounces in weight, we always add the “fl” when referring to fluid ounces. I hope that helps!

  6. What is the alternative to sugar-free condensed milk? Is that something I can find in Whole Foods or Walma

    Reply

    • Hi HA,

      There is no alternative to the sugar-free condensed milk, there are no packaged versions that we are aware of.

      Reply

      • Lol sorry, I should have clicked the link above. I just made a batch of the sugar-free condensed milk (amazing!) and the key lime pie. It’s just out of the oven, and I am so impressed by the results. This recipe will be my go-to dessert from now on!

        • I’m glad it worked out well for you! Thanks for stopping by with the update 🙂

          Reply

  7. I’ve made this recipe 4 times. It was great everytime. I use a different low carb sweetened condensed milk recipe each time and it gives it a different feel, but this is the base recipe I make and everyone loves it.

    Reply

    • Thank you for your kind words, Layla! I’m so glad you like the recipe 🙂

      Reply

  8. This may be the costliest recipe yet! Please tell me I don’t have to go and buy a fan forced oven!

    Reply

    • Hi Belinda,

      You certainly don’t need a new oven. We just have 2 options in Australia, one that has a fan and one that doesn’t 🙂

      • so a regular oven uses the same temp’s?

        Reply

        • Hi Marica,

          Yes the same temperature can be used for a regular oven.
