Dense and fudgy blondies packed full of white chocolate, topped with a cute pink frosting and sprinkles – there is so much to love with these Funfetti Frosted Birthday Cake Blondies. These are a fabulous treat for any occasion, and travel really well!
I truly love a good blondie. The light brown sugar and melted butter combo gives the best chewy texture that is so comforting. This is a great bake for so many things, but the best for when you need a bit of comfort food. You can easily make the blondie and eat it without the frosting, but it does add a more fun flair!
TIPS FOR THE BEST Funfetti Frosted Birthday Cake Blondies
- Brown Sugar: This is crucial to the perfect fudgy texture and deep flavour. You could use dark brown soft if you’re really in a pinch. Light brown is definitely your best friend in blondies.
- Melted Butter: This is what gives the bake that oh so Instagrammable shiny, crisp top. Don’t skip this step!
- Melted White Chocolate: This gives the bake its richness and sweetness. Be really careful melting the white chocolate as it is prone to burning!
- Frosting: This recipe creates a good thick layer of frosting. To prevent the buttercream from splitting, make sure your butter (and all other ingredients) are at room temperature.
For these Funfetti Frosted Birthday Cake Blondies, I use a basic 8′ square pan (I like this one), and recommend using an electric or stand mixer to really combine the butter and sugars (with a mixer like this).
