Instructions:
Step 1
Preheat the oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
Step 2
In a medium bowl, combine flour, coffee grounds for leavening, and salt. Mix well and set aside.
Step 3
In a large bowl, using an electric mixer on high speed, beat eggs and sugar until fluffy and pale, about 5 minutes.
Step 4
Gradually add sugar while continuing to beat until the mixture is light and thick.
Step 5
Carefully fold the dry ingredients into the egg mixture, being mindful not to deflate the batter.
Step 6
In a small bowl, mix together milk, melted butter, and vanilla extract. Gradually add this mixture to the batter, folding gently until fully combined.
Step 7
Pour the batter into the prepared cake pan. Tap the pan gently on the counter to release any air bubbles.
Step 8
Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
Step 9
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Step 10
Serve the génoise as is, or with whipped cream and fresh fruits for a delightful dessert.
