Date and oat slices

15/03/2020 by Judith 14 Comments

Date and oat slices

After several attempts I finally mastered perfect date and oat slices, having the right amount of filling and being firm enough to hold. Made with wholesome ingredients, these energy packed slices are ideal for picnics, lunch boxes or simply a snack between meals.

Jump to Recipe Print Recipe

Ingredients:

For the filling:

  • 300g dried dates, chopped
  • 40g granulated sugar
  • 100ml water (approx)
  • 2 teaspoons vanilla essence

For the crumble:

  • 200g plain or all purpose flour
  • 2 teaspoons baking powder
  • 150g butter (unsalted)
  • 120g oats (plus a few extra oats to sprinkle over the top)
  • 120g granulated sugar

Equipment needed to make date and oat slices

  • Chopping board
  • Sharp knife
  • Kitchen scales
  • Measuring jug
  • Medium sized saucepan
  • Stirring spoons (one for the dates and one for the crumble mixture)
  • Teaspoon
  • Knife
  • Large bowl
  • Sieve
  • Non stick baking parchment
  • 20cm by 30cm (approx 8" by 12") baking tin (or equivalent size)

How to make date and oat slices

To make the date filling, place 300g dates in a pan with 40g granulated sugar, 2 teaspoons vanilla essence and 100ml water.  Simmer until the dates have softened and the mixture resembles pulp.  Add more water if needed.  Leave the mixture to cool. 

Preparing the date filling

To make the crumble mixture, sift 200g flour into a bowl and add 2 teaspoons baking powder. Rub in 150g butter (or use a food processor).  Stir in 120g oats and 120g granulated sugar.  

Line the tin with greaseproof paper or a non stick lining sheet.  Place half the crumble mixture into the base of the baking tin and press into place with the back of a spoon.  

Spread the date mixture over the crumble base, leaving a 10 mm gap around the edge so that the filling doesn't seep out while it is baking.

Date and oat slices ready to be baked

Cook in the centre of the oven, gas mark 5, 190 oC, 375oF, until golden.   For an Aga, bake on the grid shelf on the floor of the roasting oven and raise to the third shelf for a few minutes towards the end of the baking time to brown.

Tips

  1. Ensure that the first layer of crumble is packed firmly into the base of the baking tin.
  2. If you would like to make a vegan version, a plant based margarine can be used instead of butter.
  3. The date and oat slices are delicious cold, but can also be reheated and served warm with cream, custard or ice cream.
  4. The date slices can be stored in an airtight container for several days.

    After several mixed results trying to make vegan date slices, this one finally worked fantastically well.

    I used 350g of dates rather than 300g plus 40g of sugar as I wanted a fuller date flavour whilst reducing the amount of added sugar (besides which, dates are already very high in natural sugars).

    Using a food processor/blended really helped to get a good consistency for the base and topping. I also added 75 of pecan nuts, pushing them into the topping.

    My oven is fierce, so I baked on 100c for around 25 minutes. After 15 minutes the pecans were beginning to show signs of browning too rapidly/excessively, so I brushed the topping and the pecans with a generous amount of soya milk and then returned to the oven.

    I allowed the mixture to cool before cutting into slices, and they were delicious, as good as ones I have purchased in health food stores and National Trust cafes.

    Than you for this great recipe!

      Thank you for taking the time to let me know that you enjoyed these date slices. I make them regularly as they are a favourite in my house! The addition of the pecans sounds a tasty variation 🙂

    Tasty but way too much sugar for me. I won’t put sugar in the dates next time as they are naturally sweet and much less in the main mix

      Thank you Sue for trying this recipe and for your feedback. One of the things I like about this recipe is that it is flexible. The sugar can simply be omitted from the date filling if you wish to make a reduced sugar version of these date slices. I haven't tried the crumble mix without sugar but it may work with slightly less sugar.

        Thank you Judith for your reply. I tried your recipe again this week and omitted the sugar in the dates. I also used caster sugar instead of granulated and they were delicious. Have recommended to my friends and family 😊
