Sourdough Cranberry White Chocolate Blondies
These sourdough blondies are a copycat recipe of Starbucks Cranberry Bliss Bars. White chocolate and cranberry blondies are given an upgrade with the addition of sourdough discard. Cranberry bliss bars with sourdough starter are tangy and flavorful, frosted with a cream cheese frosting, then drizzled with white chocolate and sprinkled with dried cranberries. This sourdough blondies recipe is a fun treat to share!


Blondies are a fun bar cookie similar to a brownie, but without the chocolate. Part cookie and part cake, blondies are always fun to eat! These are a Starbucks copycat recipe of their holiday Cranberry Bliss Bar recipe – except with the addition of sourdough starter!
The slight tang of the sourdough starter discard pairs so well with the dried cranberries, cream cheese frosting and white chocolate drizzle.
The possibilities are pretty much endless here – you can throw practically any ingredients together and make a yummy, cakey, delicious treat!
These blondies are so soft and cakey. The cranberries and the yummy cream cheese frosting… Seriously, these are almost cake!

What size pan did you use?
Hi Beth! Use an 8×8 pan (thanks for letting me know I forgot to include that – mommy brain strikes again! 🙂 )
These sound absolutely divine!
They are a work of art, Jenni! Just gorgeous.
Mmmmn! Your blondies look great! I wonder if peanut butter blondies would work too?
This recipe is great! I always forget about Blondies! Cranberry, white chocolate, and cream cheese..there really isn't anything in this recipe NOT to like:) Lynn @ Turnips 2 Tangerines
These look beyond delicious! Cranberry and white chocolate and cream cheese equals irresistible!!
I think I could eat that frosting on its own. It looks so delicious! And the cranberry-white chocolate combination sounds like a winner! Have to try that.
Wow, these look awesome! I've never made blondies – i think that needs to change 😉
Oh these sound heavenly Jenni.
I often wonder about the classifications of certain recipes, it is not always that easy.
It was great fun baking with you guys this month and I can't wait for the next theme
Thank you for the welcome message on my blog
I'm having trouble with your link. Only photos and no words or recipe. But I love the idea of white chocolate and cranberries! A deadly combo!
Blondies, bars or cakes, they look wonderful! Nice job!
Yum! I love your photos – soft, golden base, creamy topping, cranberries winking like jewels. Beautiful.
These sound so good – what a great use for sourdough!
