5 Secrets To The Perfect Cookie

Tips & tricks to achieve the most delicious cookies of your life!

Why these are my FAVORITE Sugar Cookies for Sandwiches

The cookies start with a cake mix! That means that the sugar cookies are simple to make and bake.
This recipe makes a super soft cookie but it also holds its shape. Both qualities which are super important when making cookie sandwiches.
They hold up to frosting. Sometimes cookies can be too thin or have too many other flavors and you lose the frosting. Not with this cookie.
The cake mix sugar cookies bake up nice and thick which creates a wonderful base for the sandwich cookie.

Ingredients Needed

Cake Mix Sugar Cookies

Vanilla Cake Mix-The perfect base for a cake mix sugar cookie.
All Purpose Flour-Added to help give the cookies the nice and thick structure you want in a sandwich cookie.
Eggs-Putting an egg or two in a cookie dough not only binds the dough but helps with the soft texture.
Vegetable Oil-The chosen fat for this sugar cookie recipe, melted butter would work great here too.
Sour Cream-Adding a couple of tablespoons of sour cream to a cookie recipe helps them from being too sweet.
Granulated Sugar-For rolling the cookie dough in before baking and adding a great texture to the outside of the cookie.

Raspberry Cream Cheese Frosting

Cream Cheese-Added to the Raspberry Frosting for a tangy taste and creamy texture.
Butter-The perfect ingredient for any buttercream because it is smooth and delicious.
Vanilla Extract-Added in a small amount to help give the frosting an extra special taste.
Salt-Putting just a small amount of salt in a sweet recipe balances all of the flavors.
Powdered Sugar-This powdery sugar is perfect for a light and fluffy frosting recipe.
Freeze Dried Raspberries-Used in this buttercream so that you get all of the raspberry flavor without any added moisture.

How to make Sugar Cookie Sandwiches with a Cake Mix

In a medium bowl combine cake mix with flour and whisk to combine. Add eggs, vegetable oil and sour cream. Using a hand held mixer {stand mixer or mix by hand}, mix the ingredients until just combined.
Use a medium cookie scoop to scoop cookie dough into a bowl with the granulated sugar. Roll the cookie dough in sugar to coat.
Place the sugar coated cookie dough mound onto a silicone mat {or parchment} lined baking sheet. Form the dough into a small round disc.
Bake cookies for 8-10 minutes or until set and the edges begin to turn golden brown. Remove from the oven and allow the cookies to cool on the baking sheet for at least 5 minutes before moving to a cooling rack. Continue until all of the cookie dough is baked.
Cream together the softened cream cheese and butter in a large bowl with a hand held mixer until smooth. Add vanilla extract and powdered sugar one cup at a time, mixing after each addition with the hand held mixer until combined. Continue until all of the powdered sugar is added. Add a pinch of salt and stir in by hand. Finally add the freeze dried raspberries and mix using the hand held mixer until the raspberries are completely incorporated and broken down into smaller pieces.
Lay the cookies out onto a baking sheet. Half of the cookies should have their bottoms facing up.
Add a tablespoon or so of raspberry frosting to the bottom of half of the cookies. Make sure the frosting is covering the bottom of the cookie but there is a bit of lip around the edge.
Then take the other half of the cookies and place the bottom of the cookie on the frosting, press slightly and serve.

Filling Alternatives:

Nutella-The combination of chocolate and hazelnut is always a good idea, especially between two sugar cookies.
Caramel-Whether you make your own or buy it from the store, caramel would be a delicious filling choice.
Chocolate Frosting-Chocolate goes great on a sugar cookie and would spread perfectly between two cake mix sugar cookies.
Jam-A strawberry, raspberry or even blackberry jam would be a fun surprise in the middle of the cookies.
Lemon Curd-Lemon and sugar cookies are another great combo! So why not?

Tips for make the BEST Sugar Cookie Sandwiches

Use a cookie scoop to keep all of the cookies a uniform size.
Cool the cookies completely before adding the filling. If you add the filling to warm cookies it will melt and the cookies won’t hold up.
Don’t overfill the middle of the cookie. In fact, it is best to leave a bit of room around the edge because when you add the top cookie the filling will smush down some.
Add sprinkles, nuts or mini chocolate chips to the outside of the filling by rolling the filled cookie in them. This adds a wonderful appearance and texture.

Frequently Asked Questions:

Can I use a different kind of cookie?

Different kinds of cookies would work great for these sandwich cookies. In fact, these Brownie Cookies, Chocolate Chip Cookies and Snickerdoodles would all be fabulous choices.

What I love about using a Sugar Cookie is that they are so versatile and go with so many different filling options.

What is the best way to store Sandwich Cookies?

Sandwich cookies are best stored in the refrigerator. Depending on the filling you choose they may be able to be left at room temperature but will keep longer in the fridge.

Do I need food coloring for Sugar Cookie Sandwiches?

No, you do not need to have food coloring to make Sugar Cookie Sandwiches but if you prefer color you might want to. Adding a bit of food coloring to the sugar cookie dough or to the frosting could transform the cookies into colorful bites.

Can I turn these Sugar Cookies into Ice Cream Sandwiches?

These Sugar Cookies would be wonderful for ice cream sandwiches. The important thing to remember when choosing your cookie is that it is strong enough to hold up to the ice cream.

It is also important the cookies are soft in texture because they will need to be frozen. A super crisp cookie that is frozen with ice cream in the middle doesn’t usually work as well as a soft cookie.

Can I freeze these cookies?

These Cake Mix Sugar Cookies can be frozen for up to 3 months as long as they are in a good airtight container. In fact, you can freeze the cookies alone without frosting and frost them once they thaw or you can freeze them with the frosting.
