Creating this intricate macaron mosaic requires a pinch of insanity and a whole lot of patience, but the result is a stunning work of art to be proud of.

To begin, you’ll need to create your design. I used a cereal bowl to trace a circle on a piece of paper for my guide, and then sketched out my design. The sky is the limit with your inspiration here. Look to nature, fashion, home decor, or anything that lights your fire to help you imagine your design!
I decided to outline my final design in sharpie so it would show through my silpat clearly. Keep in mind, the smaller the sections of your design are, the more time consuming it will be.
I filled in my sections with colored pencil to give myself a better idea of how many colors I would need to divide my batter in to. I ended up doing six which was a bit ambitious, but it ended up working out ok!
To split your batch to create multiple colors, you’ll need to prepare your meringue and sift your dry ingredients as usual, but then only fold in your drys until you’ve just incorporated them and you no longer have streaks of ingredients. If you’re looking for a run down on macaron making basics, head over to my Basic French Macaron Recipe.
At this point, you’ll separate your batter into however many bowls you’ll need for your color scheme. Like I mentioned earlier, I did six for this color palette.
Next you’ll need to add your color and bag your batter. I went for an ombre effect with my blues and my yellows. Two of my yellow shades ended up being a bit too close for my liking, so make sure you differentiate the amount of color between shades.
I love using this trick from Sweet Mac Shop for my ombres. You start with your lightest shade, and then for each of the following shades, you double the amount of food coloring. So for example, for my blues, I started with a smudge of brown, one drop of blue, and a smudge of yellow. For the next portion I did two smudges of brown, two drops of blue, and one smudge of yellow. For the third I doubled again and did 4 smudges of brown, 4 yellow, and 4 drops of blue.
Repeat this same process with your yellows starting with 1 smidge of brown and 1 drop of yellow, then 2 smudges of brown and 2 drops of yellow, then 4 smidges of brown and 4 drops of yellow. Here’s the food coloring I use to mix up my shades! I was out of my Americolor brown so I ended up using Wilton Brown.
Obviously you can customize these colors to whichever color scheme you’re going for, but here’s a rough framework if you’re looking to recreate this waves and sunset mosaic.
As you add each color, you’ll need to finish the folding (macaronage) process for each shade. After every few folds, wiggle your bowl back and forth several times and see how the batter settles. You want it to still have a few soft lines/ridges to avoid over mixing as you pipe through small openings.
Once you’ve finished folding each shade, fill them into separate piping bags fitted with a coupler, and rubber band the wide opening off to prevent your batter from spilling out. Place plastic wrap over the coupler opening as well to prevent your batter from drying as you work. Before you pipe anything, start preheating your oven to 295 degrees.
Now comes the first tedious part. At this point, you’ll need to place your sketch on a baking sheet underneath a silicone mat. Once you’ve situated your first bag of batter with a small round piping tip (Wilton 3 or 4), you can begin filling in each section of your sketch with small dots. Make sure to leave enough room between the dots so they don’t smash together as they bake. Do not tap your tray after piping your dots. Pipe a substantial amount of extra dots outside of your sketch as extras to fill any gaps. See photo for reference!
Once you’ve filled in each section with the matching color of piped dots, you’ll need to rest your tray until your dots have formed a dry skin on the outer layer. I usually have a fan gently blowing air on my trays to speed up the process and rotate my tray every five minutes to ensure even drying. Once your oven is preheated and your dots have a formed a dry skin, bake for 11-13 minutes, or until your dots no longer wiggle when you gently tap the side of them. Bake for one extra minute at a time and check if you need to add more bake time.
While your dots are baking, you’ll need to pipe your other two macaron circle layers that will become the base of your cake. Trace another circle using the same bowl to create a plain template, and place it on another baking sheet with a silicone mat. Remove your small piping tip on whatever color you’d like to show on the outside of your layer. From here you can either awkwardly hold a large round tip over your bag as you pipe, or you can place your bag into a larger piping bag fitted with a large round tip.
Start piping the rim of the circle about 1/4 inch in from your templates line. Continue working your way in, switching to your other colors if needed until you’ve piped the full circle. Bang your trays on the counter to remove any air bubbles and pop any large bubbles remaining. Set your first circle layer aside to rest and repeat with your second circle layer.
Rest each layer until the dry skin has formed and then bake at the same temperature for 20-24 minutes or until your shell no longer wiggles when gently pressed on the side. Wait until circles have cooled completely before attempting to cautiously remove them from the mat. I found it worked well to place my hand on the circle and then flip the tray over, and THEN peel the mat from the top while I held the layer with my hand.
For assembly, I ended up using a large round tip to pipe some Swiss meringue buttercream dollops on my bottom layer. I then placed my top layer on that, and then spread more Swiss meringue buttercream on top of that using an offset spatula. I wasn’t super happy with the cleanliness of my edges, so if I had to do it again I’d recommend just piping the top layer of buttercream on with a round tip, and then carefully smoothing it out from there!
Next comes the most tedious part, the placement of your macaron dots! I used a toothpick to lightly sketch where my sections were to give me a reference point. Then, carefully remove one section of your piped dots at a time, and place them in your section. A pair of tweezers can help with precision if you’re having trouble just using your fingers. Once you’ve repeated this process with each section, go back in with more white Swiss buttercream and pipe the dividing line between your sections! See video for full demonstration of mosaic placement.
Whew. This project is a serious labor of love, but if you’re like me and love a good challenge, it will be incredibly rewarding! If you want to make this a quicker process you could certainly pipe larger pieces or have less sections and it would still be beautiful. Tag me on Instagram @the.white.whisk if you give it a try!
