Step 1

Sift together almond flour, powdered sugar, cocoa powder, and espresso powder into a large bowl and set aside.

Step 2

In a stand mixer fitted with the whisk attachment, whisk the egg whites on medium speed until they become foamy, then add in the cream of tartar.

Step 3

Turn the mixer up to medium-high and gradually add in the granulated sugar. Once all the sugar is added, turn the mixer to the highest setting and whisk on high until stiff peaks form.

Step 4

Using a spatula, gently fold in half of the dry ingredient mixture until fully combined. Then gently fold in the remaining dry ingredients.

Step 5

Continue to gently fold the batter until it reaches a “flowing lava” consistency. You should be able to make a “figure 8” with the batter before it breaks. As soon as you reach this consistency, stop mixing! If you over-mix the batter, the macarons won’t rise properly in the oven.

Step 6

Line a large baking sheet with a silicone mat or parchment paper.

Step 7

Scoop batter into a large piping bag fitted with a large round tip. Hold the piping bag perpendicular to the silicone mat and pipe 1 inch rounds.

Step 8

Pick up the baking sheet and drop it onto the counter 3-4 times to help bring any air bubbles to the surface of the macarons. Then use a toothpick to pop any visible air bubbles to make a smooth surface.

Step 9

Let the macarons sit at room temperature for 30-40 minutes or until a skin forms on the surface. You should be able to lightly touch the surface without any batter being disturbed.

Step 10

While the macarons are resting, preheat the oven to 300°F.

Step 11

Bake one sheet at a time on the center rack of the oven for 13-15 minutes or when they do not move on their “feet” when touched.

Step 12

Let the espresso macarons cool completely on the baking sheet before removing them. They should easily peel off when fully cooled.

Step 13

In a stand mixer fitted with the paddle attachment, cream together the softened butter and mascarpone cheese until completely smooth.

Step 14

Then add in the powdered sugar and beat on slow until combined.

Step 15

Add in the coffee liqueur, then beat the frosting for 2-3 minutes on high speed until light and fluffy.

Step 16

Match up your shells before filling, and then turn one side over.

Step 17

Very lightly dust the tops of the macarons with a little extra cocoa powder. Then pipe the Kahlua mascarpone frosting in the center and top with the other shell.

Step 18

Put the assembled tiramisu macarons in an airtight container, then place them in the fridge for mature for 12-24 hours before eating for the best taste/texture.
