1. One of the best things about this recipe is that there’s no need to chill the cutout cookies before baking, which means you don’t have to worry about them losing their shape during the baking process. 

2 The sugar cookies have a delicious, sweet, buttery flavor with a hint of vanilla and a light crunch that quickly dissolves in your mouth.

What type of buttercream are we using and why?

American buttercream is the perfect filling for these buttercream sandwich cookies.

This buttercream recipe is perfect and so simple to make. (For further hints and tips about buttercream see this post.) 

It is sweet and compliments the sugar cookies perfectly and will set really well creating the perfect texture. 

American buttercream is also super easy to colour.

What equipment do I need to make the buttercream sandwich cookies?

Stand Mixer, I would highly recommend that you have a stand mixer but a hand whisk will do the trick, it’s the first part of the recipe where the butter is still quite firm that is the most difficult part.

Greaseproof paper- I like using Tesco baking paper. Look out for a comparison post of different types soon.

Rolling pin – I have a large nonstick one, similar to this one.

Spacers – These are great, you place them on either side of your dough to ensure the dough is rolled out to an even consistency.

Rolling pin with spacers – If you don’t have either of the above then this is a great purchase as it has the two in one!

Cookie Cutters- these come in all shapes and sizes, as a starting set this is great for round cookies. You will also need a smaller heart cookie cutter to get this design

Gel colours

Piping Bags, I really like these ones from Amazon, they have a nice non slip feel on the outside. They are also the perfect size! (no risk of over filling!)

1M Wilton nozzle or similar.

Hints and tips for creating buttercream sandwich cookies

A piping bag and nozzle are great to get the design on these cookies however, you can spread a nice thick layer of buttercream onto the bottom cookie instead.

I added a small amount of pink gel to the buttercream, which gave this dusty pink colour.

Sprinkles you can get from pretty much anywhere but see the notes below about the cake suppliers I use.

When adding sprinkles, do this just after piping the buttercream, if you leave it too late the buttercream will have set. A crust will form on top of the buttercream and this will mean the sprinkles won’t stick.

 Once you are ready to pipe the buttercream, take care not to pipe right to the edge as it will spill out of the sides when you place the other cookie on top.

Buttercream Recipe

This is a fairly basic buttercream recipe and one which I find works really well. This one is icing sugar heavy so if you like your buttercream sweet then this is perfect. However, more recently I have been using a buttercream that is more butter heavy. It only has 2 ingredients plus your flavouring! I feel this is a super special recipe and why I sell it, you can purchase it here.

Basic Buttercream

Cook Time 10 minutes
Course Dessert
Servings 750 g


  • 250 g unsalted butter
  • 500 g icing sugar
  • 1 tsp vanilla extract
  • 25 ml milk or cooled boiled water


  • Beat the butter very well in a bowl on a high speed until lighter in colour.
  • Add in the icing sugar and combine using a fork (this will save those massive clouds of icing sugar, also your hand/ stand mixer, see this post for more buttercream hints and tips)
  • Once the icing sugar has been combined with a fork add in your vanilla extract.
  • Using your mixer, add teaspoon of milk/ water at a time until your buttercream is at the right consistency for your needs.

Where to buy more specialised cake equipment

I buy a lot of my cake decorating bits and bobs from Cake Stuff (including Colourmill oils like this pink one which I love) I also go through a company called Topcashback which earns me cashback rewards on not just this purchase but so many more. Use this link to sign up.

I hope you enjoyed this tutorial and will give buttercream sandwich cookies a go, if not for Valentines Day but for any other special occasion. As always, Happy Baking!
