Crafting Your Rhubarb Cheesecake Bars Inspired by Nigella Lawson

Right then, let’s get these beauties in the oven! First things first, get that oven preheated nice and hot to 200°C (or 180°C fan – you know how ovens can be a bit different!). You’ll need a 20cm square baking tin, and I always line mine with baking parchment. It just makes getting them out afterwards a doddle, trust me.

Step 1: Pop your sliced rhubarb into a little baking dish in a single layer. Sprinkle over those 40g of caster sugar. We’re going to gently roast this for about 10 to 13 minutes. You want it tender, but still holding its lovely shape – no mushiness allowed here! Once it’s done, let it cool completely.

Step 2: Now, take about half of those lovely roasted rhubarb pieces and pop them aside. The rest? We’re going to blend them into a smooth, vibrant puree. This is going to be our gorgeous swirl later on.

Step 3: For the oat base, which is just divine, grab a saucepan. Melt your butter over a low heat, then stir in the demerara sugar and golden syrup. Keep stirring until it’s all smooth and gorgeous and smells amazing.

Step 4: Toss in your rolled oats until they’re all coated in that syrupy goodness. Spoon this mixture into your prepared tin and press it down really firmly. I like to use the back of a spoon or even the bottom of a glass for a nice, even layer. Bake this base for about 10 minutes until it’s just lightly golden. Take it out while you do the next bit – it needs to cool slightly.

Step 5: While the base is cooling, turn your oven down to a gentler 170°C (or 150°C fan). Now for the cheesecake filling! Beat your cream cheese and caster sugar together until it’s super smooth and creamy. Honestly, no one likes lumps in their cheesecake, do they?

Step 6: Add the lemon juice and your eggs, mixing everything together until it’s just combined. Don’t overmix it at this stage, you don’t want to make it airy like a soufflé!

Step 7: Pour about half of this glorious cheesecake mixture over your slightly cooled oat base. Spread it out gently to cover the base evenly.

Step 8: Now for the magic! Scatter those reserved roasted rhubarb pieces evenly over the cheesecake layer. They’ll peek through beautifully.

Step 9: Spoon the remaining cheesecake mixture over the top, and give it a gentle smooth over. Try and get it as even as you can – it just looks so much prettier.

Step 10: Take your beautiful rhubarb puree and drop little spoonfuls all over the top of the cheesecake. Then, using a skewer or the tip of a knife, gently swirl the puree into the cheesecake mixture. Don’t overdo it, just a few gentle passes to create those lovely patterns. It’s like painting with dessert!

Step 11: Into the oven it goes for 30 to 35 minutes. You want the edges to be set, but the centre should still have a slight wobble. It will firm up more as it cools, so don’t be tempted to overbake it!

Step 12: Once baked, let them cool completely at room temperature. Seriously, resist the urge to dive in! Then, pop them in the fridge for at least 2 hours, or even better, overnight. This is key for getting those lovely, clean slices. Patience is a virtue, especially with bakes like these!

Step 13: When you’re ready to serve, dust them with a little icing sugar, maybe add some fresh raspberries for extra colour and zing. They really are a slice of countryside heaven, a bit like my easy classic carrot cake or a slice of my strawberry Victoria sponge.

Serving Suggestions for Your Rhubarb Cheesecake Bars

These bars are pretty spectacular on their own, but here are a few little touches that I think take them from lovely to utterly divine:

Fresh Raspberries: Always my go-to! The deep, slightly tart burst of fresh raspberries is just *perfect* with the creamy cheesecake and tangy rhubarb. Plus, they look gorgeous.

A Dollop of Greek Yoghurt: If you’re going for something a little lighter than cream, a spoonful of thick Greek yoghurt adds a lovely tang that complements the rhubarb beautifully.

A Scoop of Vanilla Bean Ice Cream: For a truly decadent treat, especially if you’ve warmed them *ever so slightly* (don’t overdo it though!), a scoop of good quality vanilla ice cream is pure bliss. It reminds me a bit of how lovely my easy coffee mousse is served cold.

Storing and Reheating Your Rhubarb Cheesecake Bars

Now, for the ‘will there be any left?’ part! These bars are honestly best stored in the fridge. Keep them in an airtight container, and they should be lovely for up to 3-4 days. Do make sure they’re properly chilled before you put the lid on, otherwise you might get a bit of condensation.

Reheating isn’t really their thing, if I’m being honest. They’re designed to be cool and creamy! If you’ve really got your heart set on a warm-ish dessert, you could zap a single bar in the microwave for about 10-15 seconds – *just* until it loses its chill. But personally, I think they’re perfect straight from the fridge. They’re also brilliant for making ahead for a party or just for having a little treat ready to go during the week.

Frequently Asked Questions About Rhubarb Cheesecake Bars

Got a question about these lovely bars? I’m happy to help!

Can I use frozen rhubarb?

Oh, absolutely! Frozen rhubarb is a lifesaver when fresh isn’t available. Just make sure to use it straight from the freezer without thawing it first. You might need to roast it for a few extra minutes until tender, but it’ll work just beautifully in your swirl. It’s a bit like using frozen berries in my easy classic flapjacks – works a treat!

How do I get really clean slices?

This is my trick: patience! Letting the cheesecake bars chill completely in the fridge for at least 2 hours, or even better, overnight, is the absolute key. Once they’re properly cold, use a long, sharp knife, and wipe it clean between each cut. A quick dip in hot water before each slice also helps it glide through smoothly.

Can I make these dairy-free or vegan?

While this recipe is designed around traditional dairy and eggs for that classic creamy texture, you could experiment with dairy-free cream cheese alternatives and flax eggs. However, the texture and flavour might change quite a bit, so it would be a bit of an adventure! Let me know if you give it a go!
