I have always been a big cake lover. I wanted to have my cake and eat it too, all while saving a few calories.

This one is so easy to make and the perfect combination of lemon and raspberry. I am a huge lemon fan, and this cake is just that much sweeter with the hint of raspberry to it.

This makes the perfect spring or summer dessert. You can’t go wrong with this light fruity dessert. Even my kids, who are picky dessert eaters (I know, I didn’t know it could be possible either) constantly ask me to make this one.

It comes together quickly, only requires a few simple ingredients, and tastes amazing. You will love this Diet Lemon Raspberry Cake.

What other fruit could I use besides raspberries?

I am the biggest raspberry fan. Next to fresh peaches, they are definitely my favorite.

I get that not everyone loves raspberries as much as I do (actually I don’t really get it…), so if this is the case, here are a few other fruits that would taste amazing with this recipe:

Blueberries
Blackberries
Strawberries
Cherries
Pineapple

These are the ones we definitely recommend for this recipe. You could also just do plain lemon, and not add any raspberries or any other fruit to it, if you prefer it plain.

Do I have to use diet 7 up?

You definitely don’t have to use Diet 7 Up for this recipe. I like it sugar free and light, so I fell less guilty, but you could easily switch out the diet, for regular.

Hey, Elyse, I think you’ve come up with a prize here. Seems like the Weight Watchers points would be very reasonable. When I get the ingredients I’ll have to figure it out. Thanks!

This looks so good I couldn’t wait to try it. So I just put it in the oven. I made a few adjustments – using egg white powder instead of eggs because I just can’t stand to waste yolks, using FD Raspberries and regular 7Up, not diet. Will be sharing on my blog next week. It’s for dinner with friends tomorrow so I have to wait to taste it 🙁

Not a fan of cool whip or any whipped cream, a light drizzle of lemon flavored icing put the finishing touch on it for me.
