Raspberry & Vanilla Swirl Sheet Cake

This Raspberry & Vanilla Swirl Sheet Cake not only tastes great but is really easy to make. The raspberry jam and vanilla go really well together in this deliciously moist cake. 

After I made my Blueberry & Lemon Swirl Loaf Cake, I knew it wouldn’t be my last cake with a jam swirl! Raspberries are one of my favourite fruits and they go so well with lots of flavours; vanilla being one of them. I don’t know if it’s just me, but raspberries do seem to have quite a short shelf life. They can also be a little pricey compared to other fruit. 

These reasons, plus the fact you probably have some raspberry jam in you cupboard; mean using jam is a great option. The jam also helps provide extra moisture to the cake which fresh raspberries wouldn’t always. 

As with a lot of my favourite cakes, this Raspberry & Vanilla Swirl Sheet Cake is really easy to make. It doesn’t take much time at all to make and then you can forget about it while it’s in the oven. You then just need to allow it to cool without the need for any further effort. These are my favourite sort of cakes to make during the week when you don’t have hours after work to make a fancy cake. My Peanut Butter & Chocolate Banana Bread is another one of these recipes. 

This is such a delicious cake. The yogurt helps keep the cake really moist and give it such a lovely texture. If you don’t fancy using raspberry jam, strawberry would work really well too.

      Thanks πŸ™‚ Sheet cakes might be an american term or tray bakes but I quite liked it so I’ve gone with it haha x

    I always think sheet cakes sound much more appealing than tray bakes (That I think is the UK term) Always makes us sound like we’ve just used an old oven tray! Your sheet cake looks so light and fluffy – I’m very tempted to make a swirl cake myself this afternoon. Thanks so much for joining in once again with #BakeoftheWeek

      Haha. I didn’t think of it like that but that made me laugh. Tray bake makes me think of millionaires shortbread or something like that. Thank you πŸ™‚ I love how easy they are.
