Mix the peanut butter in the yoghurt until smooth, then top with a few small dollops of jam. Swirl with a spoon, but don't mix in completely so the jam sits mainly at the top.
Break up the biscuits in half, then arrange in the tub of yoghurt
Refrigerate overnight or for around 6-8 hours to allow the biscuits to absorb the moisture and become soft.
Top with another optional drizzle of peanut butter and dig in!
Notes
I used a 0% fat Greek yoghurt, but any type of thick yoghurt will work. You can use flavoured yoghurts if you prefer more sweetness. Peanut butter can be replaced with another nut butter, or omitted for a nut-free version.I used a lower sugar strawberry jam. Any type of crunchy biscuits will work, so pick the one you like the taste of because that's the flavour that will shine through!
