Place it into the oven to bake for 10 minutes. Pop the remaining crumble mixture into the fridge to keep cold.

Meanwhile, let’s make the filling. If you haven’t already, finely grate the zest of both lemons then juice them.

Pour the tin of condensed milk into a large bowl and add the lemon zest and juice. Give it a really good stir until everything is nicely combined.

Made these yesterday and I was not disappointed. Had to work out the recipe quantities for a 26cmx35cm tin but once I’d done that it was simple. They were very delicious and a definite keeper! Thanks for the recipe, it will become a firm favourite I’m sure 😊

Hi Dawn. You weren't missing anything! I only introduced printable recipe cards a couple of years ago - I've been blogging for over 10 years. As you can imagine there's a bit of a back log to catch up on and there's only little old me to it haha. I've just updated this recipe to include one, so if you take another look, you should be able to print it out :) Emma x

Emma

Tuesday 9th of March 2021

Hi Jane. I've not frozen these before so I'm really not sure. Maybe give it a go with one or two bars and see? If you do try it I'd LOVE to hear back and see if it worked? Sorry I couldn't be more help, Emma x

I want to make this recipe what is condensed milk. Is it like the eagle brand sweet, or like carnation evaporated. Please let me know.

Emma

Hi Rae. I’m not sure what ‘Eagle Brand’ is (not sure we have that here in the UK). Sweetened condensed milk is a very thick and sweet milky liquid. Don’t use evaporated as that is WAY too thin. Emma x
