Back to School · Easy Lunch Box Snacks
Dead-easy, freezer-friendly lunch box snacks you can make in the Thermomix with pantry staples, so you batch cook once and coast through the whole week.
What are the easiest lunch box snacks to make in the Thermomix? A four-ingredient flapjack oat slice, a moist chocolate sheet cake that freezes in neat squares, a choc muesli slice and choc-banana muffins are the quickest wins... all made with pantry staples and all freezer-friendly, so you can batch cook once and be sorted for the week.
Back-to-school season means lunch boxes to fill five days a week, and it is so easy to default to pre-packaged bars and yoghurt pouches. But those little packets add up fast, both at the checkout and in the ingredients list. The good news? Snacks are some of the quickest things to make in the Thermomix, and with a little freezer prep you can stay ahead of the whole term.
The easier a snack is to make, the more likely you are to actually make it. The goal is not the fanciest treat made once... it is a reliable cadence of nourishing, home-cooked food for your family, week in and week out. Every recipe here has a short ingredient list, so it is genuinely doable on a busy weeknight.

Flapjack Oat Slice in the Thermomix
Just four ingredients and one base recipe with thousands of options. Keep the mix-ins vague (dried fruit, nuts, seeds, coconut) so you can tailor it to taste and to allergy needs. Press it into a Reusable Square Cake Tin Liner and there is no lining or greasing.

Moistest Chocolate Cake in the Thermomix
Built for the freezer. Bake it flat, cut it into neat squares and freeze what you do not need... they defrost by lunch time and tessellate straight into the lunch box. Bake it in a Deep Sheet Pan with a Reusable Sheet Cake Liner and it lifts out clean without a scrap of baking paper.

Choc-Banana Muffins in the Thermomix
Incredibly moist and more chocolate than banana, and they happen to be egg-free, dairy-free, vegan and naturally nut-free, so they clear most school allergy rules. Bake them in your Silicone Bar Moulds and freeze a batch.

Frequently asked questions
Can you freeze lunch box snacks?
Yes. The chocolate sheet cake, choc muesli slice, choc-banana muffins and flapjack oat slice all freeze well. Freeze them in individual portions so you can pull out exactly what you need, and most will defrost in the lunch box by the time they are eaten.
What are good nut-free lunch box snacks to make in the Thermomix?
The choc-banana muffins are naturally nut-free, and the flapjack oat slice is easily made nut-free by leaving out the nuts and using extra dried fruit, seeds and coconut in the mix.
How do I stop slices sticking to the tin?
A reusable liner is the easiest fix... it drops straight into the tin so there is no lining or greasing, and the slice lifts out clean. For individual bars and muffins, naturally non-stick bar moulds do the same job.
Want to make snack time easier in your Thermomix?
Skip the lining and greasing for good. Our reusable liners drop straight into your tin, wipe clean and last batch after batch, so a homemade lunch box snack is never the hard option again.
