Step-by-Step Guide to Perfect Mary Berry Date Slices

Time needed: 45 minutes

Follow these simple steps to create the perfect batch of date slices.

  1. Prepare the Filling

    In a saucepan, combine the chopped dates, water, lemon juice, and brown sugar. Cook over medium heat, stirring often, until the dates soften and form a thick paste. Remove from heat and let it cool.

  2. Preheat the Oven

    Set your oven to 180°C (350°F) and line a baking tin with parchment paper.

  3. Make the Oat Crust

    In a bowl, mix the flour, oats, brown sugar, and baking soda. Pour in the melted butter and stir until the mixture resembles coarse crumbs.

  4. Assemble the Layers

    Press half of the oat mixture into the base of the baking tin, creating an even layer. Spread the cooled date filling over it, then sprinkle the remaining oat mixture on top.

  5. Bake

    Place in the oven and bake for 25-30 minutes, or until the top turns golden brown.

  6. Cool and Slice

    Let the date slices cool completely in the tin before cutting them into squares.Mary Berry Date Slices

Step-Specific Tips

  • Let the filling cool slightly – A warm filling spreads easily, but if it’s too hot, it may soften the oat base.
  • Press the base firmly – A well-packed base ensures the slices hold their shape when cut.

Why This Recipe Is a Must-Try

  • Naturally Sweetened – The dates add rich, natural sweetness, reducing the need for added sugar.
  • Great for Meal Prep – These slices keep well, making them perfect for batch baking.
  • Satisfying Texture – The chewy date filling contrasts beautifully with the crisp oat layers.

Pro Tips for Perfect Date Slices

  • Use soft dates – Medjool or other naturally soft dates work best. If using firmer dates, soak them in hot water before cooking.
  • Don’t overbake – The top should be golden but not overly crisp to maintain a chewy texture.
  • Line the tin with parchment paper – This makes it easier to lift the slices out for clean cutting.

Fun Variations & Ingredient Swaps

If you want to experiment, try these creative twists:

  • Coconut Date Slices – Add 50g shredded coconut to the oat mixture for a tropical touch.
  • Chocolate Drizzle – Melt dark chocolate and drizzle over the cooled slices for extra indulgence.
  • Spiced Date Bars – Add ½ tsp cinnamon or nutmeg for a warm, aromatic flavor.

Avoid These Common Mistakes

  • Skipping the lemon juice – This balances the sweetness of the dates and prevents them from tasting overly rich.
  • Not cooling before slicing – Warm slices may fall apart; allow them to firm up before cutting.
  • Using instant oats – Rolled oats provide the right texture; instant oats can make the base too soft.

Mary Berry Date Slices FAQs

Can I use fresh dates instead of dried?

Fresh dates have a higher moisture content and may result in a wetter filling. If using fresh dates, reduce the added water and cook until thickened to achieve the right consistency.

Why is my oat crust crumbly?

If your crust is too dry, it may need a little more melted butter to bind the mixture. Pressing the base firmly into the tin also helps prevent crumbling.

Can I make these date slices vegan?

Yes! Simply swap out the butter for a dairy-free alternative like coconut oil or plant-based butter. The rest of the ingredients are naturally vegan.
