Celebrate ANY day with these amazing birthday cake cookies! They have the decadent texture of a blondie combined with fluffy buttercream icing that’s destined to melt in your mouth.
Today’s birthday cake cookies are the result of a conversation with Katy. It isn’t anyone’s birthday but they remind me of when Brady was a toddler. He loved my birthday cakes and so he brought me his teddy bear one day and told me that it was Teddy’s birthday. Being the mother that I am, I acted surprised and horrified that I’d forgotten such an important occasion and got to work mixing up cake batter and buttercream icing. Little Brady was so impressed with the results that a few days later, wouldn’t you know he found another stuffed animal who was celebrating its entry into this world. We celebrated a lot of birthdays back then :).
So last week I asked Katy “If you could invent any cookie, what would it be?”. Without missing a beat she said “birthday cake cookies.”
Hmm. I was intrigued by that and started running ideas by her. I chose the flavoring so that the cookie mimics the taste of a homemade birthday cake and the texture of these cookies is really most closely akin to a blondie, for extra deliciousness. Top it off with a generous layer of fluffy buttercream icing and a sprinkling of rainbow candies and we have a treat fit for the most special of days!
Recipe Ingredients
- Sugar
- Self-rising flour
- Brown sugar (light or dark brown sugar is fine)
- Butter (I use unsalted but if you only have , use that)
- Eggs
- Sprinkles
- Vanilla extract
- Butter flavoring
- Almond extract
How to Make Birthday Cake Cookies
First, place the butter in a bowl and melt it in a microwave. You can also melt it on the stovetop.
If you want, you can even build a fire in the backyard and melt it over that if you have a hankering. Or, if you live in the south right now, just put it out on the back porch for a few minutes and that should do the job.
The point is, you need to melt your butter.
Add in sugars and stir well by hand.
In a separate mixing bowl, beat the mess out of your eggs. This is when you get out all those frustrations.
Add flour, eggs, and flavorings to the sugar mixture.
Stir that up really well by hand.
If you want to make sprinkle cookies, toss in a handful of those and stir in well.
Spray a 9×13 baking dish with cooking spray and add the cookie dough.
Bake your birthday cake cookies at 350 for about 30 minutes.
When they’re done, the will still be soft in the center but golden brown all over.
Top with buttercream frosting
In a large bowl, cream the butter and about 1 cup of confectioner’s sugar with an electric mixer until light and fluffy. Add the butter flavoring, half of the milk, and remaining sugar and beat again until smooth and creamy, scraping down the sides and adding a little extra milk if needed.
Ice the cooled cookie bars.
Top with sprinkles, if desired. Allow icing to set by leaving uncovered for about half an hour.
How good do these birthday cake cookies look? I hope you enjoy them as much as my family does!
Storage
Store leftover funfetti cookies in an airtight container in the fridge for up to 5 days. You can also freeze them for up to 3 months, but the icing won’t be as creamy once thawed.

Every day of your life is a day worth celebrating 🙂
Hi Christy, I first came across your site while searching the web for anything interesting. It was a very low time for me in my life, (I will not bother you with the details). Since reading that first article, and the one’s I have recieved there after, some things seem to go a little easier. You some how make it seem like you are writing to me personally, like you know just what kind of a day I had. It isn’t always right on the head but I can take bits and pieces from each article and work from there.
I know that I am just one of many, of the thousands of people who follow you, but I thought that I would let you know how this one, felt. Thanks
John, YOU are so very important to me! Each and every one of you are!! I am so glad that you have found a blessing by being here and I am so blessed to have you here. Thank you for letting me know that things are a bit easier and I pray that they will get better and better as the days go by! ~Christy
Katy, great idea! Christy, thank you for the recipes that I already have the ingredients for. Buttercream is truly a wonder of the world. My grandma always said, only the bored have spotless houses the rest of us are too busy living in our homes! Keep making the wonderful memories with your family.
I like the way your Grandma thinks Pamela!!!
Love this post! I just made a cookie cake. You better bet next time it will be covered in frosting & sprinkles! Isn’t it wonderful to know, even in your own opinion of your shortcomings, you are still nailing it with your kids?? That’s all we can ask for. My 10 year old daughter has friends that LOVE coming to our house. I’m like, “Your room looks like a cyclone has hit it & you would think the vacuum cleaner has never been used.” My daughter says, “But you make us peanut butter & crackers with marshmallows melted on top & give us ice cream & judge our beauty contests.” I guess unfolded clothes is no match for melted marshmallows! 🙂 You are doing LOTS of stuff right Christy!! 🙂
And Christy, I appreciate your light hearted approach to what plagues most of us working women. (Trying to keep up with housework, while making a life with our families). My uncle always told me to clean my house when my kids were grown. That I would never get the time back with my kids. SO TRUE!!:)
thank you, Christy, and thank you, readers
this is an inspiring place to visit
Thank YOU Susan!! I am so glad you are enjoying it!!
My, my, my……. Christy, you can see an overwhelming response that supports and validates your belief that being with those most important to you tops a spotless house. However, I doubt you really need that validation since you seem to know yourself and your priorities well, and are generous enough to spread the joy to your readers.
And see, with people like you around here setting the example and encouraging me with how you live your lives, how can I not glean wisdom from that? Y’all are a blessing to me!
Christy, you are the blessing, and such a wonderful, positive influence. Thank you for sharing your life with us! We love you! God bless!
Thank you Reta!! Blessings to you!
Christy..this is disgusting. Hire help to assist with your
Housekeeping & do your laundry! you are setting a
Bad example for your children!
I’m afraid you’ve missed the point of the type of example I want to be for my children. I’d rather show them imperfect but devoted love than have them live in a showplace home. Our house is paradise because of the people in it. The dirty dishes are there because of wonderful family meals. I’ll accept being “disgusting” and a “bad example” in your eyes if my priorities make me so. Thanks!
I now have even more respect for your frankness about your house. It was quite brave of you to share this part of yourself knowing there was a risk of people calling you disgusting and a bad example. Clearly, you are neither. No one else thinks so. Thanks again.
Christy I just had to make Katy’s cookies today but since there was no one around with a birthday my neighbors and I decide it was to celebrate “Thank God we made it another day” day. Worth celebrating with a yummy cookie like yours. Guess tomorrow we can come up with a different reason.
Now Marsha, that sounds like the very best thing to celebrate!!!! haha!!! Love it!
