    Ingredients

    Here’s what you will need for this recipe. Quantities and full directions are in the recipe card near the end of the post.

    • oats – in this recipe use porridge/rolled oats, or jumbo oats for the basis of the oat bars.
    • dates – I have used Sayer dates here to make the date caramel, in the form of chopped dates. Medjool dates are larger with a caramel flavour and can be used too.
    • cacao nibs – these are crunchy and slightly bitter, rather like dark chocolate. They are crushed pieces of cacao beans (the raw form of chocolate). You can often get them in the health food aisle in supermarkets where you normally find nuts and seeds, or from health food shops. Also available on (aff link) Amazon. Can be replaced with chocolate chips (I prefer dark chocolate chips).
    • coconut oil – this can be replaced with butter if needed. Coconut oil is good for you, as a healthy fat source.
    • vanilla bean paste – adds flavour to complement and enrich the date caramel.
    • light brown sugar – to sweeten. If you prefer you can swap this for coconut or date sugar (at the same proportions), or honey (use less as it is sweeter).
    • egg – to bind the oat bars together.
    • flour – self-raising flour helps create a fluffy texture and a little rise.

    Why These Healthy Oats Bars make a Great Healthy Snack

    Full of slow release energy from the oats, a slice of this will keep you going if energy levels are flagging! It’s a much healthier way to have a sweet treat than my usual recipes, but you won’t feel deprived after eating it.

    Cacao nibs are considered a superfood as they are rich in antioxidants and nutrients. Oats are a great source of fibre too and dates are a natural energy booster.

    These bars are great as a homemade alternative to packaged bars.

    How to Make Date Caramel

    What is date caramel I hear you ask and how do I make it?! Just soak some chopped dates in a little water, add vanilla bean paste and blend with a hand blender and you end up with the thick dark spread you can see here.

    When I first saw this on Pinterest where it features in a lot of vegan recipes in place of standard caramel, I knew I had to try it. Sweet but not full of white sugar!

    I used a different kind of dates to the recipes I saw, which tended to use Medjool dates, as I had a bag of chopped Sayer dates in the cupboard to be used up. The taste is sweet like caramel and the consistency is lovely and thick.

    Baking in a Slow Cooker

    As usual I’ve baked these healthy oat bars in my slow cooker, the main advantage for me is there is no need to worry about watching over it like when baking in the oven, you can get on with something else at the same time.

    Slow cooker baking also uses less energy and is preferable to the main oven when the weather is hot.

    Step by Step Instructions

    Here are my step by step instructions with hints and tips to help you make these healthy oat bars with date caramel perfectly every time. Quantities are in the recipe card at the end of the page.

    Step 1. First start the date caramel. Put the chopped dates in a small bowl and cover them with a little cold water. Leave to soak until soft (this will take 15-20 minutes usually). Then drain most of the water, add the vanilla bean paste and use a hand blender to blend it until smooth.

    Step 2. In another bowl, cream together the coconut oil and light brown sugar, using a wooden spoon.

    Step 3. Add the egg and vanilla bean paste and beat well.

    Step 4. Stir in the oats, flour and cacao nibs and mix well to combine.

    Step 5. Line the base of your slow cooker pot with baking paper, and press the mixture into the slow cooker pot.

    Step 6. Put some kitchen towel under the lid to stop drips, put the lid on, and cook on high for approximately 1.5 hours or until the oat slice is starting to brown around the edges and firm up in the centre.

    Step 7. Remove the oat slice from the pot using the edges of the baking paper to lift it out, and let it cool on a rack.

    Step 8. When cool, spread the date caramel over the top of the oat bars and slice it into pieces.

    Oven Method

    If you don’t use a slow cooker this can be baked in the oven. Bake for 20-25 minutes at 180°C / 350°F or until golden brown.

    Variations

    There are lots of tasty ways to adapt this recipe:

    • replace cacao nibs with chocolate chips
    • add a handful of chopped nuts such as hazelnuts, walnuts, almonds in with the oats for crunch
    • add a handful of raisins, sultanas or chopped apricots for additional bursts of sweetness
    • add a little peanut butter in with the caramel to make peanut butter date caramel
    • drizzle peanut butter (thinned with a little milk) or white chocolate over the top to make it look more bakery style

    Storage

    Keep these oat bars in an airtight container for 3-4 days.

      Ooh this sounds so good Lucy, sweet chewy and delicious. Really like your date caramel idea, dates are such a good way of getting sweet stickiness into things without using sugar. Thanks for joining in with We Should Cocoa.

      I have a huge sack of cacao nibs just waiting to be used. Shall have to pull them out I think! I love the idea of this date caramel – Chloe can’t have dairy so this would be a cool ingredient to use in her birthday cake or as a treat. Another fab recipe Lucy xx
