A Macaron filling that is Quick and Easy to Make
The process of making macarons can be quite lengthy so having a quick and easy filling recipe up your sleeve can be a life saver! I make this buttercream filling while my macarons are in the oven or when they are cooling, but it would work just as well to make it in advance and store it in the fridge it until you are ready to use it. Just remember to take it out of the fridge early to give the butter cream enough time to soften to piping consistency. If you have more time you could combine it with some soft salted caramel and make chocolate fudge & caramel macarons – yum!.
Production!
If you are making a large batch of macarons for an event or an order it’s very safe to double or triple this recipe. The consistency is great for either a large round piping nozzle for super quick filling, or a star shaped nozzle could be used to add interest and visual texture macarons:

Macaron Resting time
24-48 hours or more
This buttercream filling is not going to add too much moisture to macarons so it will take up to 48 hours in the fridge for the macarons to mature and reach the perfect texture. The good news is they will also last really well in the fridge without going too soft too quickly.

Use good quality cocoa powder
I used a dark cocoa that has a nice flavour and as the cocoa is the star of the show in this recipe the flavour of the cocoa is very important!

Step-by-Step Instructions to make Chocolate Fudge Buttercream Macaron Filling
Step 1 – Beat the Butter
Put 100g butter into a large mixing bowl and beat using a stand or hand mixture on a medium to high setting for 3-5 minutes. The butter will lighten in colour and texture as shown in the images below
Step 2 – Add Ingredients
Sift into the butter – 30g cocoa powder, 1/4 tsp salt and 215g icing sugar (powdered sugar) and pulse the mixer until the icing sugar and cocoa are combined with the butter. Then add in 1 tsp vanilla extract and 2tbsp double cream (heavy cream) and turn the whisk up to medium high and whisk for around 2 minutes.

Step 3 – Add cream to Achieve Desired Consistency
If the buttercream is not yet at the correct consistency for piping, add in another tbsp of cream and whisk for another minute. The image below shows the consistency that I like buttercream for macarons to be – see the little points on the whisk … that’s what I look for!
