Easy Microwave Berry Crumble

A fruity microwave berry crumble in less than 5 minutes? Yes please. The best part? You won't even have to share.

We all know my love for single serving recipes burns brightly. However not matter how many microwave recipes I make, the microwave crumble will always have a special place in my heart. It's just SO easy and so customizable. Plus it has the added bonus of requiring only two dishes... it's the perfect lazy girl (or guy) sweet treat!

My microwave crumble obsession first began with my famous microwave apple crumble. Since then, I've realized that it can be made with pretty much any fruit. So since it's the season of love (and we had a stash of frozen berries) I knew it was time to make a berry version. This microwave berry crumble is a hit and quite possibly my favourite version I've made. The ingredient list is also packed with whole grains, fibre, and natural sweeteners to help make this a crumble you can have all day long.

What Ingredients do I Need for this Microwave Berry Crumble?

Berries- I've used both fresh and frozen berries. I personally find frozen work a tiny bit better because they soften faster. I like using a combination of raspberries and blueberries but any berries will work. If you are using a bigger berry such as strawberry, don't forget to slice them up!

Oats- Minute oats, quick oats or rolled oats all work in this recipe so choose whatever you use most often (may favourite are these).

Cinnamon & Ginger- The secret to a good crumble is in the spices. I love the addition of ginger to this but it is also 100% okay if you would like to omit it.

Cornstarch- Using a little bit of cornstarch helps thicken up the berry filling a little bit more. You can also substitute it for arrowroot powder if you aren’t able to use cornstarch.

Walnuts- These are 100% optional. I add them for a little extra crunch when I'm using frozen berries but they aren't necessary.

Maple Syrup- Maple syrup adds some natural sweetness to this berry crumble. I personally love the subtle maple flavour it brings to this and have not tried substituting with any other liquid sweeter. If you decide to try using honey etc. let me know how it goes in the comments! Ps. you can also try a sugar-free maple syrup like this one!

Coconut Oil- I use coconut oil for a lot of my baking for the sole reason that I love the subtle coconut flavour it brings. However if you don’t have coconut oil on hand feel free to substitute it with butter!

Oat Flour- I love using oat flour in my recipes for a little extra fibre and whole grains. You can buy pre-made oat flour (like this one or you can just blend an equal amount of oats in a blender or food processor until smooth ( this is what I do). Note that I have never tested this recipe with any other type of flour, it *should* work but I can’t 100% say.

Can I use an Oven?

This is a question I’ve gotten asked a lot on many of my single serve microwave recipes. Some people just don’t have a microwave, or they don’t feel like using it or they’d just rather put it in the oven-and that’s totally okay! I personally like using the microwave because it’s just so quick and convenient. There’s no need to wait for the oven to heat up, and it takes only 2-3 minutes to cook. So I’m all about getting my berry crumble as quickly as possible. However if you’re someone that appreciates the slower things in life you can bake this in the oven at 350 degrees F for about 25 minutes or until the crumble begins to brown.
