Matrimonial Cake, my Granny's date squares are our best dates recipe - whether from Scotland or Canada the result is so good with dates sandwiched in an oat crust.
In a saucepan, cook together all the ingredients except the lemon juice. Cook gently until soft (about 20 minutes). It's ready when the dates soften into a paste. (If you prefer having a perfectly smooth paste, then blitz it for a few seconds in a food processor.) Set aside to cool then add the lemon juice.
For the Oat Shortbread Crumble:
Preheat the oven to 180°C/160°C fan/360°F/Gas 4 and grease a baking tin (I use a 27x19cm tin) with either butter or even better, use a non-stick tin.
Cream the butter and sugar together either by hand using a wooden spoon or better, in a food mixer/processor.
Add oats, flour, soda and vanilla until well combined.
Press no more than half of the mixture into the greased baking tin - either with your fingers or using a flat spatula to make the bottom layer even and thin. Spread on the date paste using a spatula and smooth it out until even.
Top with the oaty shortbread crumbs and gently pat it on top to keep it in place but not too much - it's better to have a crumbly look to the light topping.
Bake in the oven for about 30 minutes or until the oats are lightly toasted.
Cool on a wire rack then place in the fridge for about 30 minutes, remove from the tin and cut into squares - or bars, if you prefer.
Notes
Like macarons, this is even better eaten next day - and the next and next...Storage: up to a week in an airtight container in the fridge. Best eaten at room temperature so remove from the fridge about 20 minutes before serving.Variation: Don't have dates? Replace dates with prunes and add the zest of an unwaxed orange (see more on oranges on my market produce guide). Measures: Please note that all my recipes are best made using digital kitchen scales in precise metric grams. Both ounces (and cups) are given as an approximate guide.
