Single serve recipes really are the best. They make just the right amount, always hit the spot, and are always easier than making a whole batch of something. A few single serve recipes I find myself coming back to time and time again are my 5-ingredient single serve cinnamon roll, single serve protein cookie, healthy gluten-free mug cake, and now (& especially this time of year) this single serve apple crumble. It’s perfectly sweet, super easy to make, and just as delicious as your favorite apple crumble recipe. I even managed to make this recipe with just 5 ingredients. So the next time you’re craving a delicious fall treat, whip up this single serve apple crumble, cozy up on the couch, and enjoy! 🥰

Sam’s Recipe Tips

Use a firm but juicy apple (e.g. Honeycrisp, Pink Lady) so pieces soften but don’t disappear.
Ensure the topping is crumbly, not doughy – mix just until the oat/almond flour mix clumps slightly.
Let it cool for a few minutes before digging in – this helps juices settle.
For extra depth, stir a pinch of nutmeg or allspice into the apples before topping.
