Oat & Date Crumble Slice | Classic Recipe

Classic Oat & Date Crumble Slice – an oaty base, sweet date filling and crumbly topping… it doesn’t get much better than this!

If you’ve been reading Bake Play Smile for a little while now, you’ll know that I am a big, BIG fan of classic and traditional slices. My favourite cookbooks are those really old, yellowing recipe books that have been handed down through generations. I always think that if a recipe has been passed down from one family member to another, it’s got to be a keeper… and this oat & date crumble slice is exactly that!

Although I do have to admit that I’ve changed the crumble recipe around just a little… just enough to make it even more delicious! But I’ve kept the date filling the same as the original recipe. There’s some things that you just shouldn’t go changing, right!?

Oooh one little thing that I should mention is that this recipe makes quite a lot of date filling. Personally, I like lots of the sweet date mixture, but you can always leave a little aside if you’d like your date layer to be a little thinner.

And one more thing… this oat & date crumble slice is super sweet! It’s definitely one for all of the sugarholics out there. In fact, not only does it make the perfect afternoon tea treat, it’s also one kick-ass dessert. Just warm it up, add a big scoop of vanilla ice-cream, and get ready for total and utter bliss. Mmmmm!!!

So if you want to bring back some delicious childhood memories, then make this oat & date slice. Your tummy will be forever thankful! xx
