I know I've been sharing a lot of lunchbox recipes lately but I'm really trying to give my children some variety so I'm trying out lots of new ideas. Hence the Homemade Le-Snak the cute Baby Bell Cheese Lady Birds and my Inari Sushi Pockets.

These homemade LCM bars have been another huge success. I only give my children commercially prepared LCM bars occasionally because they're expensive and full of chemicals and preservatives.

I justify the sugar by telling myself at least they are having rice bubbles which are fortified with vitamins and minerals. Now that I have discovered how easy the homemade version of LCMs is to make, I know I will never buy the commercial variety again.

LCM Bar Gets Children's Approval

When my daughter tried the bars she said they were exactly the same as the bought LCM's. That was a surprise to me because usually, the kids object to anything homemade.

LCM Ingredients

  • I like to use salted butter and vanilla as you get that delicious "sweet and salty" flavour.
  • Decorate the bars with melted chocolate and use the chocolate to "glue" on the mini smarties.
  • The marshmallows can be any colour depending on what you would like the finished colour to be.

I decided to decorate these bars with melted chocolate and mini smarties to give them extra lunchbox appeal. However, they're definitely classified as "sometimes food" at best.

Thermomix LCM Bar Variations

There are so many possible variations to this recipe.

Next time I make these I'm going to vary the ingredients and add some nuts and dried cranberries.

  • Substitute rice bubbles for Cocoa Pops and top with a milk chocolate drizzle and chopped nuts.
  • Use white chocolate marshmallows and stir through cranberries and pistachio nuts. Top with white chocolate and garnish with crushed pistachios.

Watchpoint & Tips

  1. The mixture will be really sticky but it doesn't tend to stick to a plastic spatula.
  2. Press the LCM bar firmly into the tin so it is compressed and solid.
  3. LCM bars are best stored in the fridge.
  4. For a more sturdy bar add a thin layer of chocolate all the way over the top of the slice.

The LCM bars are not exactly health food. But, on a positive note, at least I know what ingredients are in them, and the kids will love them!

Next time I make these I'm going to vary the ingredients and add some nuts and dried cranberries. They still won't really be healthy but I think the flavour would be fabulous.

Initially, I used to make these bars on the stove but the Thermomix makes everything so much easier. If you've tried these by hand before and cursed you will be pleasantly surprised at how easy the Thermomix makes the process.

      Hi Crystal
      There is nothing that would go off in this recipe so they can be kept for quite a while. I would say 2 weeks. The only concern would be the rice bubbles becoming less crisp.

    What a great idea to make these at home since you can control the ingredients. Reminds me of rice krispy treats I used to eat. Love the idea of adding fruit and nuts for a healthier version.

    I have never heard of Thermomix. The recipe sounds good, but I'm just not sure how this translates if you don't have this machine.

      Hi Amanda, The Thermomix has just arrived in the US so you will undoubtedly be noticing it soon. The machine mixes, cooks, steams, food processes, kneads etc.

    They look really great and so simple to make in the Thermomix. Love the drizzle of white chocolate over the top of them as well, so pretty.
