Three gluten-free muesli slices tied with baking paper
Gluten-Free Muesli Slices

For those who have subscribed to my blog, you may notice that the orange oat slice in the free baking cookbook is slightly similar to this recipe for gluten-free muesli slices. As it is a popular recipe in the cookbook, I thought I would add some extra ingredients to make the slice more fibre-rich and interesting with a decadent drizzle of dark chocolate.

* *
What main ingredients are in the Muesli Slice?

Gluten-Free Oats 

Store-bought or my homemade gluten-free PLAIN flour blend

Xanthan gum – to bind the baking ingredients together

Gluten-Free Baking Powder – to give the slice a bit of a rise

Desiccated coconut – to add flavour, texture and sweetness

Butter and golden syrup – to add a caramel flavour

Nuts – My first choice is macadamia nuts, but using hazelnuts, pecans or almonds works well too. Just remember to keep them whole for that extra crunch.

Seeds – Pumpkin seeds and sesame seeds are my favourite in muesli bars, but feel free to add sunflower seeds and/or chia seeds. They are packed with nutrition and fibre.

Dark chocolate  – to drizzle over the tops of each muesli slice, adding extra flavour and healthy antioxidants.

Sugar – white and brown – Feel free to lessen the sugar content if you prefer your slice to be less sweet. I would reduce the white sugar over the brown sugar as the latter gives a nice richer caramel flavour.

Some baking tips:
Baking paper

Use a sheet of baking paper to line the cake tin. Make sure the edges are hanging above the mixture or over all four sides. This will help when removing the entire baked muesli slice from the tin after baking.

Pressing down

Using the back of a large spoon, press the raw muesli mixture firming into the cake tin. This needs to be done quite thoroughly as the firmer you press, the better the slice texture will be.

Scoring

Once the muesli mixture has been pressed down with the spoon, eye-ball or use a ruler to guide you when scoring with a knife. This will give an accurate grid to slice them once baked into perfect pieces without cracking and breaking off in random places.

Don’t overcook the slice

After 35 minutes of baking, the slice will be ready to remove from the oven, despite feeling slightly soft on the surface. After 15 minutes, it will harden as it cools down.

Slice when thoroughly cooled

Try not to attempt to cut the muesli slice into portions until it is thoroughly cooled.

  • Melt the butter in a small saucepan over medium heat.
  • Add the golden syrup, bicarbonate of soda and boiling water. Remove from the heat and mix well.
  • Pour the combined butter mixture into the oat mixture.
  • Add the vanilla and mix well until all the ingredients are thoroughly combined.
  • Transfer the muesli mixture to the prepared cake tin and flatten it down by pressing with the back of a large spoon. This needs to be done quite firmly, as the firmer you press, the better the slice texture will be.

  • Score the top of the slice into equal size slices. This makes it easier to slice later once cooked.

  • Using a spoon, drizzle the melted chocolate over the top of the entire muesli slice.
