    Slow Cooker Crunchie Brownies

    Brownies made in the slow cooker are so good, and these slow cooker Crunchie brownies are no exception!

    If you aren’t in the UK, a Crunchie bar is a bar of honeycomb coated in chocolate. If you are then I am sure you will know and love Crunchies as I do!

    Slow Cooker Crunchie Brownies

    Although I’m currently trying to eat more healthily, I think there is still room for the odd treat now and again. Besides, I’m going to share these with work colleagues and family, so I doubt I’ll get more than one piece!

    I put slices of Crunchie in the brownie mixture so they baked into the squares, then added extra on top, I mean you want to see them there don’t you.

    Slow cooker baking

    If you have disasters baking in the oven or just don’t have the time to keep an eye on the oven then you should try using the slow cooker to bake.

    It is cheaper than using your main oven and with the energy prices sky high it is great to have a cheaper way to get that chocolate fix! 

    I made these Crunchie brownies in a large (5.7 litre) slow cooker, in a large round silicone mould with water under it. As there is no direct contact, this means even less chance of burning.

    Please note though! If you are using a smaller slow cooker and cooking straight in the pot, do reduce the quantities for this recipe or it would probably be too deep and the brownies would take forever to cook in the middle; in that case you might need to look out to ensure the edges don’t burn.

    So rich, soft and fudgy with crisp edges and the crunch of the honeycomb on top, my slow cooker Crunchie brownies are perfect for an indulgent treat. You get a subtle taste of honeycomb in the brownies too.

    Look how good they are, I could just dive in there now!! Will you have one square or two?

    Slow Cooker Crunchie Brownies

    Ingredients

    Grab these ingredients from your baking cupboard. Don’t forget you’ll find the quantities in the recipe card at the bottom of this post.

    • butter
    • dark chocolate
    • milk chocolate
    • self-raising flour
    • eggs
    • light brown sugar
    • Crunchie bars

    Instructions 

    1. Cut the butter into small pieces and put it in a bowl. Break the chocolate up into pieces and add to the same bowl.
    2. Microwave for 1 minute on high or until melted. Stir until it is smooth. Allow to cool.
    3. Using a hand mixer, mix together the eggs and light brown sugar for 5 minutes at high speed, until thickened and frothy.
    4. Pour the chocolate/butter mixture over the egg mixture and fold in gently until mixed.
    5. Sift in the flour and again fold in gently until incorporated.
    6. Pour the brownie mixture into a greased silicone mould. I used a large round one.
    7. Chop up two of the Crunchie bars and put the pieces on top of the brownie mixture.
    8. Pour one large glass of water into the base of your slow cooker pot. Place the silicone mould in the pot, in the water.
    9. Place a clean tea towel under the lid of your slow cooker, place it on the slow cooker, and fold up the edges of the tea towel so they are over the lid. This stops drips from falling onto the brownies.
    10. Cook on high for approx 2 to 2.5 hours, until the brownies are cooked through apart from in the centre. I prefer them this way but you can always leave them in until completely set if you prefer.
    11. Remove the silicone mould from the slow cooker and allow to cool completely. If you can wait, then leave the mould in the fridge overnight and remove from the mould the next day – this will help the brownies to set and prevent them from breaking up when you take them out of the mould.
    12. Cut into pieces, chop the last Crunchie bar and add pieces and crumbs on top. Yield 12-16 pieces.

        Thanks Emma, the idea came from this month’s Treat Petite challenge which was to bake with your favourite chocolate bar. When I get around to adding the logo to the post and adding it there that is!
