Happy June! We’ve officially entered my birthday month and, to celebrate, I wanted to make something fun and a little unique… birthday cake biscotti!
Growing up, I was never really a huge fan of birthday cake in general – I would ask for brownies or some kind of skillet cookie for my birthday dessert. Now, that’s not to say that I don’t appreciate a good birthday cake, it’s just not something that I would crave!
This birthday cake biscotti is truly the exception. Though, it’s not cake at all – it’s literally birthday cake flavored biscotti. As a lover of all things coffee (and all things you can dip into coffee), this is one of my favorite biscotti recipes yet.
Why you’ll love birthday cake biscotti
Everything you love about cake in a biscuit form. Crunchy biscotti + birthday cake flavor = heaven! Not to mention, you can dip this funfetti biscotti into your coffee. You can’t do that with cake!
You’ll have them for weeks! If stored properly, this birthday cake biscotti will last up to a month!
They’re fun and easy. Not to mention, birthday cake biscotti is such a unique treat to make for yourself or someone else! Think about it, when was the last time you had birthday biscotti? Probably never.

Ingredients
To make birthday cake biscotti, you’ll need:
- All purpose flour – Feel free to swap for whole wheat flour!
- Sugar – I use pure cane sugar in this birthday cake biscotti recipe.
- Butter – I used salted butter in this recipe purely because I didn’t add any additional salt but feel free to use unsalted butter if that’s your jam!
- Eggs – You’ll need two!
- Baking powder – Baking powder helps to leaven biscotti (AKA helps it to rise)!
- Vanilla – For this recipe I used fresh vanilla beans from Selefina Spices but feel free to use vanilla extract if you’re unable to order it in time! I would recommend vanilla bean paste over vanilla extract as the flavor will be much better.
- Butter extract – My secret ingredient to helping this biscotti taste like a birthday cake. If you can find it, cake batter extract works beautifully too! But TBH, butter extract does basically the same thing and I don’t find it to be as sweet as cake batter extract!
- Rainbow sprinkles – When it comes to birthday cake biscotti, rainbow sprinkles are a must have!
- White chocolate (optional) – Want to decorate your birthday cake biscotti a bit more? Feel free to dip or drizzle your cooled biscotti into white chocolate!
If you’d like, feel free to add almond extract to your birthday cake biscotti too. Almond extract is delicious when paired with vanilla extract and is often used in a traditional biscotti recipe.
You can also swap the white chocolate for milk (or dark) chocolate. As long as you have some melted chocolate to drizzle on your cooled biscotti, you’re good to go!
How to make birthday cake biscotti
Line a baking sheet with parchment paper and set to the side.
Cream the butter and sugar together in a large bowl. Then add the eggs, vanilla, and butter extract and mix well to combine.
Add in the flour and baking soda. Beat until fully combined, then fold in the rainbow sprinkles with a rubber spatula. Using your hands, divide dough into two equal pieces and form into long oval slabs on your prepared baking sheet. You want each slab to be at least 1/2 inch thick.
Bake for 30 minutes, then allow the biscotti to cool on the baking sheet for at least 25 minutes. Once cooled, slice the dough with a serrated knife into 1 inch slabs to form the classic biscotti shape. Place the cut biscotti slices upright and bake for an additional 12 – 15 minutes, or until they’re lightly golden brown in color.
Allow the birthday cake biscotti to cool completely, then drizzle white chocolate on top! Enjoy your birthday biscotti alone or with a nice cup of coffee.


Frequently asked questions
Have a question not answered below? Leave me a comment and I’ll do my best to answer it!
Is biscotti a cookie or bread?
Biscotti is a twice baked cookie!
Though, a lot of people refer to them as biscuits (and that isn’t necessarily wrong).
What do you eat biscotti with?
Typically, you’d pair biscotti with a drink as they can be sort of dry on their own. Coffee or tea is perfect!
Should biscotti be hard or soft?
In between hard and soft!
Your biscotti should be firm – not too hard that it’ll break your teeth, but not too soft that it doesn’t hold it’s form.
How should I store my birthday cake biscotti?
I always store my homemade biscotti in an airtight container (like a tin) in order to keep them crisp! They typically last up to a month stored like this.
Pro tip: If storing biscotti that was drizzled with white chocolate, make sure to place parchment paper (or wax paper) between each layer of biscotti to prevent the chocolate from transferring from biscuit to biscuit!
