Birthday Cake Cookie Bars Recipe!

Hello lovelies,

If you were to go with me to a desert restaurant, what are you guessing I’ll order? I’ll give you a hint… it starts with C, ends with E.

Yup, that’s right, a cookie! Whether it’s just a normal cookie, a cookie bar or warm cookie dough – you can guarantee that’s what I’ll be picking every. single. time!

So, as you’ll have gathered, I love me a cookie and more recently, I’ve been loving baking a delicious batch of cookie bars. There’s something about a cookie bar that hits the spot perfectly. It satisfies my cookie cravings, massively.

When it comes to cookie bars, I’ve dabbled in a few different flavour combinations (which I’ll be sharing throughout the year) but one flavour, I hadn’t ever made before and fell instantly in love with is the flavour ‘birthday cake’.

It only took one bite for me to know that I had to share this recipe with you all! It’s simplistic flavour wise, it’s nothing too crazy BUT damn, is it good.

Ultra vanillary, sweet, gooey centre goodness with a slight crunch on the outside – do I need to say anymore?

If this cookie bar has caught your eye and got you wanting more, you know the drill my loves. Keep on scrolling below and you’ll find the recipe:

Do you see what I mean about it’s a simplistic recipe, with simplistic flavours but it just slaps, it really does.

So, if you’ve got a birthday coming up and you’re sick to death of cake, why not try a cookie bar instead? I highly recommend.

Also, is there any flavours you’d like me to add to a cookie bar recipe in the future? Let me know as I’m always willing to try new things.

Let me know in the comments below if you make these cookie bars yourself and if you do, what your thoughts are on them. Are you a cookie bar lover too? Have you tried the birthday cake flavour before?

Sending you all tons of love & hugs as always,

Elle xo
