M&S Milk Chocolate Teacakes Soft marshmallows on a crumbly chocolate biscuit base, covered in smooth milk chocolate. Perfect for teatime or as an after-school treat. 16 per pack.   100% of the palm oil in M&S products is responsibly sourced and certified by the RSPO. More information on the M&S palm oil strategy can be found on the M&S corporate site.   Our teacakes have been unwrapped to reduce overall plastic use and no longer come individually wrapped. Plus we’ve removed over 2 million units of plastic packaging by moving to a fully recyclable paper packet.
