This 3 Ingredient Granola is crunchy, perfectly sweet and nutty- you won’t believe it was made in the microwave and took less than 5 minutes! It makes the perfect quick breakfast or snack and you don’t ever have to worry about running out of granola ever again!

Happy Monday! Who else has routinely had granola as part of their breakfast? Granola is definitely a staple food in my diet, especially homemade granola. Not only is it cheaper but you can customize it to your liking of sweetness, add-ins and combination of flavours. I always prep granola on the weekends so that I have some on hand throughout the week, but sometimes I snack a little more than I expect and run out for the next morning… *gasp*. HAVE NO FEAR OF RUNNING OUT OF GRANOLA ANYMORE THOUGH BECAUSE today… I have for you one of the best hacks you should know!! and keep in the back of your pocket: MICROWAVED GRANOLA. Yup, microwaved granola. In one mug, no mess, no oven, no fuss & its ready in 5 minutes.

It starts off with 3 basic ingredients with the optional pinch of salt and/or vanilla. Mix all the ingredients into a microwave safe mug and then just pop that into the microwave for a total of 2.5 minutes! Remember to keep an eye on it for the last 20 seconds so it doesn’t burn.

And there you have it, crispy, crumbly, nutty & sweet ol’ granola for any of your breakfast needs. It’s delicious over smoothie bowls, banana icecream bowls, yogurt bowls & honestly even on its own or a bit of almond milk. Get creative with the flavours by substituting the types of nut/seed butter you use and all the additional add ins you can add!

I really hope you try making granola in the microwave and love it as much as I do because it’s:

  • vegan, dairy & oil free

  • can be made gluten & allergy free

  • customizable & versatile

  • made in one bowl

  • only 3 simple ingredients & made in less than 5 minute

  • crunchy, sweet & toasty

  • & totally a magical crowd pleaser

Tips and Tricks to making Microwave Granola

  • Use ROLLED oats for the proper crisp-ness of granola

  • I personally love maple syrup as a sweeter, but if you decide to use any other liquid sweetener, be sure to play around with the ratios for sweetness! If you add less sweetener, add more nut butter.

  • Any nut or seed butter can be used here, just make sure its runny!

  • Keep dry & wet ingredient ratios as similar as possible. If adding extra nuts/seeds or even dried fruit be sure to bump up the amount of liquid sweetener or nut butter. I add 1/2 tsp more for every 1 tbsp of extras.

  • Play around with the timing for your own microwave, every microwave is different! Keep an eye on the granola when microwaving for the second time. If it doesn’t seem to be cooked and crispy yet, microwave in increments of 10-15 seconds.

  1. I LOVE this granola recipe. I make a double batch of it about once a week so I always have some around. I’ve tried several other recipes for microwave granola and this one is by far the best! I always use honey instead of maple syrup though. I’ve also made this oil free by substituting the nut butter for unsweetened applesauce and only adding a little water. You will have to microwave it about double the time though because of the extra moisture but it always turns out just as good if not better than using nut butter! Hope that helps anyone trying to find a good oil free recipe 🙂

  2. ALL nuts have oils in them, naturally. If you are going to add nuts then it will never be oil free. When a recipe states that it is oil free, for the most part, I would think they mean no added oils.

    1. oil free as in no added oils. if you look at any oil-free recipe (that actually taste good) you need some sort of fat. just like coconut milk or avocado, it’s higher in fat but there is no ADDED oil.

  3. It’s not oil free with peanut butter in it. Pranut butter has oil in it all stirred up into the butter. Sound tasteful but not oil free.

    1. Hi mysticc,

      There are no additional oils added in! As in, no oils are used here. Peanut butter is not pure oil.

  4. Hi, I made it this morning as my pre-workout snack to carry to work to eat later in the day before I go to the gym. I love the ease of making it and it taste really good. Bye bye oven! 😄😋

  5. I made this as an afternoon snack. It was perfect! I love homemade granola but dislike baking it. Thank you!!
