Ingredients for Cookie Sandwiches

½ cup salted butter, softened – Provides rich flavor and a tender texture while creating the base of the cookie dough.

¾ cup light brown sugar – Adds sweetness, moisture, and a slight chewiness thanks to its molasses content.

¼ cup white granulated sugar – Helps the cookies spread and lightly crisp at the edges.

1 large egg – Binds the ingredients together and adds structure and moisture to the dough.

½ teaspoon baking soda – Helps the cookies spread and promotes a soft, tender texture.

1 teaspoon baking powder – Gives the cookies a bit of lift for a thicker, lighter consistency.

1 ½ cups all-purpose flour – Forms the structure of the cookies, giving them shape and stability.

½ cup jimmies sprinkles – Adds color, fun texture, and a festive look without melting into the dough.

Frosting Ingredients

¼ cup salted butter, softened – Creates a creamy, rich base for the frosting.

1 ½ cups powdered sugar – Sweetens the frosting and gives it a smooth, thick consistency.

1–2 tablespoons milk – Adjusts the frosting’s thickness for easy spreading or piping.

½ teaspoon vanilla – Adds classic flavor and warmth to the buttercream.

¼ teaspoon almond extract – Enhances the flavor with a subtle nutty note that complements the vanilla.

Tips & Tricks for making Festive Cookie Sandwiches

1. Let cookies cool fully before assembling– Since these use buttercream frosting, allow the cookies to cool for about 30 minutes so the frosting doesn’t melt or slide off when you add it.
2. Use consistent cookie sizing– A #40 cookie scoop (about 1 ½–2 tablespoons) helps keep all the cookies uniform in size, making it much easier to match them up into even sandwich pairs.
3. Lightly flatten the dough before baking– Gently pressing the dough balls into thick discs encourages more even spreading in the oven and results in flatter cookies that are easier to assemble.
4. Choose the right sprinkles & finishing touches– Use larger jimmies for the best “birthday cake” look, and if desired, roll the edges of the assembled cookies in extra sprinkles so they stick to the frosting for added color and texture.

How should I store Sandwich Cookies, and can they be frozen?

You can store these cookies in an airtight container on the counter for up to 5 days. While they can also be kept in the fridge, they tend to dry out about a day sooner there. They’re delicious served either chilled or at room temperature.

For longer storage, you can freeze the cookies (assembled or unassembled) in an airtight container for up to 2–3 months; just let them thaw in the fridge or at room temperature before serving.

Ingredients

Cookie Dough:

• ½ cup salted butter softened
• ¾ cup light brown sugar
• ¼ cup white granulated sugar
• 1 large egg
• ½ tsp baking soda
• 1 tsp baking powder
• 1 ½ cups all-purpose flour
• ½ cup jimmies sprinkles

Frosting Ingredients:

• ¼ cup salted butter softened
• 1 ½ cups powdered sugar
• 1-2 TBSP milk
• ½ tsp vanilla
• ¼ tsp almond extract

Instructions

• Preheat your oven to 350°F. Line a baking sheet with parchment paper and set aside.
• Cream the butter, brown sugar, and granulated sugar together in a large mixing bowl using an electric hand mixer on high speed. Once the butter and sugars are smooth and creamy, whisk in the egg until fully incorporated.
• Slowly whisk in the flour, baking powder, baking soda, and sprinkles until no dry pockets remain in your cookie dough.
• Use a standard size cookie scoop to drop balls of cookie dough onto a baking sheet. Flatten each ball slightly to create thick discs and bake your cookies for 12 minutes. Let your cookies cool on the counter for 30 minutes and prepare your frosting.
• Whisk together the softened butter, powdered sugar, milk, and extracts until smooth and creamy. Use a piping bag or spatula to spread frosting over the bottom of half your cookies. Top with the remaining cookies to create your cookie sandwiches. Enjoy!

Notes

You can store your cookies on the counter for up to 5 days in an airtight container. You can store them in the fridge too, but we felt they dried out about a day faster that way. These cookies are great served chilled or at room temperature.

What kind of sprinkles should I use in this recipe?

You can use any kind of sprinkles, but larger jimmies work best for a vibrant look. It’s best to avoid sanding sugar since it tends to dissolve during baking and won’t give the same colorful “birthday cake” effect.

Can I add extra sprinkles to the outside of the sandwich cookies?

Yes, you can roll the edges of the assembled cream pies in additional sprinkles. They’ll stick to the buttercream and give the cookies a fun, colorful finish, though it will use quite a few sprinkles.

What’s the best way to apply the frosting?

Using a piping bag gives the cleanest, most uniform look when assembling the cream pies, but if you don’t have one, you can easily spread a thick layer of frosting with a spatula instead.

How do I keep the cookies from spreading too much?

Make sure your butter isn’t overly soft or melted, and lightly flatten the dough balls just before baking rather than pressing them too thin. Chilling the dough for 20–30 minutes can also help if your kitchen is warm.
