Ingredients
For the Funfetti Birthday Cake Cookies
- ½ cup/125g butter salted or unsalted – if using salted, omit salt. I usually use salted.
- ¾ cup/150g dark brown sugar
- ½ cup/100g white granulated sugar
- 1 medium/large egg + 1 egg yolk
- 1 tbsp milk
- 1 tsp vanilla
- 1.5 tsp cake batter flavor I use Loranns
- 1 and 2/3 cups/200g all-purpose flour
- ¾ cup/100g cake flour
- 1.5 tsp baking powder
- 1.5 tsp cornstarch
- ½ tsp salt if using unsalted butter
- ¼ cup sprinkles
- 8 Birthday Cake Oreos
- Vanilla buttercream and sprinkles for topping
For the Birthday Cake Buttercream Frosting:
- 1 cup butter - salted or unsalted if using salted, omit pinch of salt
- 3 cups powdered/icing sugar
- ½ tsp cake batter flavor
- Pinch of salt if using unsalted butter
- 2 tablespoons heavy cream
Instructions
- Line your baking sheets with parchment paper.
- Cream the butter and sugars together in a large bowl until light and fluffy.½ cup/125g butter, ¾ cup/150g dark brown sugar, ½ cup/100g white granulated sugar
- Add the egg, egg yolk, milk, vanilla, and cake batter flavor to the butter mixture and mix until well combined.1 medium/large egg + 1 egg yolk, 1 tbsp milk, 1 tsp vanilla, 1.5 tsp cake batter flavor
- In a separate bowl, whisk together the all-purpose flour, cake flour, baking powder, cornstarch, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.1 and 2/3 cups/200g all-purpose flour, ¾ cup/100g cake flour, 1.5 tsp baking powder, 1.5 tsp cornstarch, ½ tsp salt
- Fold in the sprinkles.¼ cup sprinkles
- Scoop out the dough using a cookie scoop or spoon and weigh it on the kitchen scale, if using, until they weigh about 140 grams each before stuffing. They will weigh about 155 grams or 5.5 oz after stuffing. If not using a kitchen scale, divide evenly into 8 dough balls.
- Using your thumb, make a hole in the centre of each cookie and place a Birthday Cake Oreo in the center of each dough ball, then cover it back up completely with dough.8 Birthday Cake Oreos
- Place the dough balls on the prepared baking sheets.
- Refrigerate the dough balls overnight or for at least an hour to prevent spreading. I recommend overnight to really allow the flavours to meld together and prevent any spreading.
- Bake for 12 minutes or until the edges are set and the centers are still slightly soft.
- Let the cookies cool on the baking sheets for a few minutes before transferring to a wire rack to cool completely.
- For the buttercream, cream the butter in a bowl until light and fluffy. Gradually add the powdered sugar, cake batter flavor, salt (if using unsalted butter), and heavy cream. Beat until smooth. To get a pure white, add a small dab of violet food color gel using the end of a toothpick. The violet helps cancel out the yellow. Start very small and add more as needed, but be careful of adding too much as it will turn your icing violet.1 cup butter - salted or unsalted, 3 cups powdered/icing sugar, ½ tsp cake batter flavor, Pinch of salt if using unsalted butter, 2 tablespoons heavy cream
- Pipe the vanilla buttercream on top of each cookie using a piping bag or zip-top bag and sprinkle with colorful sprinkles.Vanilla buttercream and sprinkles for topping
Notes
What can I use if I can't find cake batter flavor? If you can't find cake batter flavor, don't worry! You can still make delicious Funfetti Birthday Cake Stuffed Cookies. Here are a few alternatives:
- Vanilla Extract: Use an additional teaspoon of vanilla extract to enhance the overall flavor of the cookies.
- Clear Vanilla Extract: Sweeter than regular vanilla extract to give it more of that birthday cake flavor.
- Almond Extract: Add a small amount (about ½ teaspoon) of almond extract for a different yet delightful flavor.
- Butter Extract: This can give your cookies a rich, buttery taste that complements the funfetti flavors.
- Imitation Cake Batter Flavor: If you find an imitation cake batter flavor at your local store, it works just as well.
Don't Skip Chilling the Dough! Refrigerate the dough balls overnight preferably, but at least for at least an hour before baking to prevent spreading and ensure a thicker, chewier cookie.
