📋 Instructions
1️⃣ Prepare the Joconde Sponge:

- 🥣 In a mixing bowl, whisk the whole eggs, almond flour, and powdered sugar until light and fluffy. Add the melted butter and sifted flour, mixing until smooth.
- 🍳 In a separate bowl, beat the egg whites until soft peaks form. Gradually add granulated sugar and beat until stiff peaks form.
- 🥄 Gently fold the meringue into the batter. Spread the mixture evenly onto the prepared baking sheet.
- 🔥 Bake for 8–10 minutes until lightly golden. Let cool, then cut into 24 equal rectangles.
2️⃣ Prepare the Coffee Buttercream:
6. 🌡️ In a saucepan, heat granulated sugar and water until the mixture reaches 250°F (120°C) using a candy thermometer.
7. 🥚 In a stand mixer, whisk the eggs, yolks, and coffee until pale and fluffy. Gradually pour in the hot syrup while continuing to whisk until the mixture cools.
8. 🧈 Add the softened butter, one piece at a time, and whisk until smooth.
