Chocolate Oat Cookie Sandwich With Maple Syrup Buttercream Recipe!

Hello lovelies,

Do you feel like you can’t beat munching on a freshly made cookie? No? I’m here to tell you differently. Why not take it up a notch by sandwiching a silky smooth buttercream between TWO freshly made cookies. Sounds good, right?

You’ll be pleased to know that this exactly what I’m bringing you today! The ultimate cookie sandwich. Its something I’ve been wanting to make for a while now SO I finally got my butt in gear and brought my cookie sandwich vision to life.

Me being me and keeping in theme with my bakes, I of course, had to make this autumn inspired.

One cookie I found myself gravitating towards when planning out this recipe was oat cookies. I just feel like they have a real autumnal feel to them, is it just me that feels that way? maybe… who knows at this point haha. Regardless, I knew that these would be the perfect cookie for todays sandwich.

Whilst the decision on the type of cookie was made pretty quick, the flavour of the buttercream was forever toing and froing on my mind. That’s when I took to Pinterest for some inspiration and not even five minutes into my search, I found the flavour. Why I didn’t think of this myself… maple syrup flavoured buttercream! Sounds bloody delicious, right?

Let’s just say, chocolate oat cookies is a match made in heaven with maple syrup buttercream. I’m chuffed to absolute bits on this pairing, it’s perfect. Just perfect.

Does that take your fancy? Is your mouth drooling? Let’s not wait about, get your baking apron on and let’s create the sandwich of all sandwiches… the recipe is below:

Category: Sweet Treat

Serves: 6-8 (depending on size)

Prep Time: 10 Minutes

Cook Time: 12-15 Minutes

Assembling Time: 10 Minutes

Overall Time: 35-40 Minutes

Ingredients You Need:

  • 150g Of Unsalted Butter
  • 90g Of Granulated Sugar
  • 90g Of Light Brown Sugar
  • 1 Large Egg
  • 2tsp Of Vanilla Extract
  • 125g Of Rolled Oats
  • 225g Of Plain Flour
  • 1/2tsp Of Bicarbonate Of Soda
  • 1/2tsp Of Baking Powder
  • 300g Of Milk Chocolate Chips

Ingredients You Need For Buttercream:

  • 100g Of Unsalted Butter
  • 200g Of Icing Sugar
  • 3tbsp Of 100% Pure Organic Maple Syrup

How To Make Oat Cookies:

  • Firstly, gather together your equipment and ingredients, line two baking trays with parchment paper and preheat the oven to 200C / 180C Fan / Gas Mark 5.
  • Secondly, in a large bowl using an electric whisk, beat together the 150g of unsalted butter, 90g of granulated sugar and 90g of light brown sugar until fluffy and fully combined.
  • Next, beat in the 1 large egg and 2tsp of vanilla extract until smooth.
  • Now, fold in the 300g of milk chocolate chips.
  • Add the 125g of rolled oats, 225g of plain flour, 1/2tsp of bicarbonate of soda and 1/2tsp of baking powder and mix using a wooden spoon until a cookie dough has formed.
  • Using a icecream scoop or your hands, take a scoop of the cookie dough, roll between the palm of your hands into a smooth ball. Continue to do this until there’s no dough left (TIP: I don’t measure the weight of my cookies, I go by eye but measure them on a scale if you’d prefer).
  • When you’ve rolled all your cookie dough balls out, place them onto your pre-lined baking trays, spaced fairly apart to allow the cookies room to spread. Using your fingers, carefully squish the tops of the cookies down slightly.
  • Place the baking trays into the oven and allow the cookies to bake for 12-15 minutes, until golden brown.
  • Once baked, take out the oven and allow to cool on the trays for around 5 minutes before transferring onto a wire rack to cool completely.

How To Make The Maple Buttercream:

  • Whilst your cookies are cooling down, it’s time to make the buttercream.
  • In a large bowl, beat 100g of unsalted butter until lighter in colour, softened and silky smooth.
  • Next, add the 200g of icing sugar, a little at a time, until the buttercream forms.
  • Add 3tbsp of maple syrup and mix into the buttercream until combined.
  • Now, place a star shaped nozzle (or any nozzle you have to hand) into a piping bag and then, add the buttercream into the piping bag also.

How To Assemble Cookie Sandwiches:

  • Once the cookies have cooled completely, it’s time to assemble.
  • Pipe the buttercream on the bottom of one cookie, making sure it’s completely covered in buttercream.
  • Finally, sandwich a second cookie ontop of the buttercream.

That’s your Chocolate Oat Cookie Sandwich With A Maple Syrup Buttercream prepared, baked and assembled, ready for you to demolish!

I feel like no picture will ever do these sandwiches justice but take my word for it, these are blooming sensational!

I’m actually on the verge of ditching writing todays blogpost and going to bake a batch of these instead… Can you tell how loved these sandwiches are? Haha.

Let me know in the comments below if you make these oat cookies sandwiches yourself and if you do, what your thoughts are on them. Have you become a cookie sandwich lover?

Sending you all tons of love & hugs as always,

Elle xo

    Maple buttercream sound quite intriguing. I’ve never been big on maple flavored items (I’m a terrible Canadian lol) but this sounds like someone I want to try. I bet my husband would love these as well, he’s a big fan of maple and chocolate chip cookies. I’m going to add this one to my list of recipes to try soon.
