  • 300g Hob Nobs

    Butter is a dairy product made from separating whole milk or cream into fat and…

  • 1 x 397g can condensed milk (we used Nestlé)
  • 3 medium egg yolks
  • finely grated zest and juice of 4 limes

  • 300ml double cream
  • 1 tbsp icing sugar
  • extra lime zest, to decorate



    The same shape, but smaller than…


  1. Heat the oven to 160C/fan 140C/gas 3.

  2. Whizz 300g Hob Nobs to crumbs in a food processor (or put in a strong plastic bag and bash with a rolling pin).

  3. Mix with 150g melted butter and press into the base and up the sides of a 22cm loose-based tart tin. Bake in the oven for 10 minutes. Remove and cool.

  4. Put 3 medium egg yolks in a large bowl and whisk for a minute with electric beaters.

  5. Add a can of condensed milk and whisk for 3 minutes, then add the finely grated zest and juice of 4 limes and whisk again for 3 minutes.

  6. Pour the filling into the cooled base then put back in the oven for 15 minutes. Cool then chill for at least 3 hours or overnight if you like. When you are ready to serve, carefully remove the pie from the tin and put on a serving plate.

  7. To decorate, softly whip together 300ml double cream and 1 tbsp icing sugar.

  8. Dollop or pipe the cream onto the top of the pie and finish with extra lime zest.

So lovely and limey. I've tried quite a few but I think this one is the best. I did cut down on the butter a bit and had no problems with a greasy base. One thing I wish was for more filling to biscuit ratio so maybe I will try a deeper dish and double up on the filling.

A firm favourite in our house, especially when we have friends over, or when we need to take something to a friend's house or a get together. It's quick, easy, reliable and tastes fantastic! I often use half lemon, half lime which tastes just as nice, and tend to use digestive biscuits for the base rather than hobnobs. Ginger biscuits would probably also work well. I don't put any cream on the top as personally I'm not keen on cream with citrus. I must have made it 10-15 times already and will continue to do so!!

This is so easy to make and it's always very well received. I use ginger biscuits for the base instead of Hobnobs.

really tasty. like others suggested I cut the amount of butter to 130g which was enough to mould the base up the sides of the tin without it becoming greasy. i also didn't bother with the sweet whipped cream. the sharp filling and sweet base were a great combo on their own.

Great filling but you do not need 150g butter for base - too sloppy. No need for cream on top. Gorgeous as is.

Made this as per recipe though didn't bother with the sweet whipped cream. Very rich but really tasty. Just don't try and eat too much in one sitting!

Please, please stop calling this a "Key Lime" pie. Key Limes are a specific type of lime that only grows in a few places. From the reviews I have no doubt it tastes good, but it is NOT a KEY Lime pie.

A key lime is just a mexican lime. Which is an Asian lime. The lime it isnt is a seedless Bears or "tahitian" lime. Key lime is a common seedy lime found anywhere in the tropics

Thats just pedantic... this is a BBC food guide, Key limes are not easily available in the UK.
