  • 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.

Lovely, the perfect key lime pie!!

So easy to make, and very tasty, I have made it twice now and each time, the lime sizes were so different, that the volume of lime juice and quantity of peel was different, but had no detrimental effect on the result. Lasted well enough for 3 days.

My 10 year old managed to make this by herself and it was delicious. Wouldn't change a thing (apart from to say take the lime juice quantity as an indicator.. you can do slightly more or less to taste without ruining it)

Very easy to do and scrumptious. It needs the cream at the end to cut out the sharpness which is not to all my kids taste. Clarice took the cream off and Charlie could not eat without an additional scoop of cream. Very rich. The base flattened after the initial 10 minutes cooking so I had to re-shape it in order to be able to pour in the mixture.

So easy but so tastey. My guests asked for the recipe they loved it so much!

I have lost count how many times I have made this now. It is a staple dessert in our household and a firm favorite of my family and friends. I substitute hobnobs for ginger crunch biscuits. It makes for an extra crunchy base and the ginger compliments the lime. I don't change anything else as it is perfect as it is.

First time in attempting anything like this, the recipe was easy to follow, and it turned out exactly as it should have. It went down a treat, and everyone was impressed. I will definitely make this again!

Super easy to make, I find that maybe there was just a tad too much butter in the base as I ended up soaking some up after the initial base bake and also needed a little more lime flavour but overall it was very delicious and got eaten between 4 in one sitting!

Great recipe, though personally found there was too much cream. When I make again I will halve the amount
