📖 Recipe
Birthday Cake Sandwich Cookies
Equipment
- baking sheet(s)
- parchment paper or non-stick cooking spray
- mixing bowl
- measuring cups & spoons
- electric handheld mixer
- silicone spatula
Ingredients
For the Cookies:
- ½ cup butter melted
- 2 eggs
- 1 teaspoon vanilla
- 1 box french vanilla cake mix
- 2 tablespoons cornstarch
- 3 tablespoons coloured sprinkles
For the Frosting:
- ½ cup softened butter
- 2 cups powdered sugar (confectioners sugar)
- ½ teaspoon almond extract (or vanilla)
- 1 tablespoon milk
Instructions
To make the Cookies:
- In a large-size bowl using an electric handheld mixer on medium speed, beat together the melted butter, eggs, and vanilla until combined.
- Sift in the cake mix and cornstarch and mix on low speed until the dry ingredients are well combined - the dough will be very soft. Fold in the sprinkles, being careful not to overmix and cause the sprinkles to bleed. Cover the dough and refrigerate for 1 hour.
- Preheat the oven to 350℉. Line 2 baking sheets with parchment paper. When done chilling, roll the dough into balls, using about 1 ½ tablespoons of dough per cookie. Place on the prepared pans, 12 cookies per pan.
- Bake the cookies one pan at a time in the preheated oven for 10-12 minutes or until golden brown around the edges. Let cool on the pan for 5 minutes before transferring to a wire rack to finish cooling completely before sandwiching with the frosting. Bake the remaining cookies.
To make the Frosting:
- In a medium bowl using an electric handheld mixer on medium speed, whip the softened butter until fluffy. Add the powdered sugar and almond extract and beat on low speed until well combined. Add 1 tablespoon of milk or more if the texture is too thick. Pipe or spread with a knife, about 1 tablespoon of frosting per cookie onto the cooled cookies. Enjoy!

These cookies are really cute! They are too sweet for my husband's and my taste, but the kids love them. My dough was still far too soft to roll (I didn't have time to leave it in the fridge quite an hour, and our house was quite warm), but I used a cookie scoop to put it on the baking sheets, and that seemed to work just as well.

Awesome!! Thank you for reviewing this recipe, Casey!

I LOVE anything funfetti so these were a super fun afternoon baking project. These cookies are incredibly soft and light, and the frosting pairs with them perfectly. Homemade sandwich cookies used to intimidate me for some reason, but now that I've made these and your mint Oreo sandwich cookie recipe, I've realized that they're actually very easy! 😊 My only tip: I recommend chilling your cookie dough balls for a couple minutes after rolling them to avoid over-spreading. 👍
