01 - Preheat the oven to 350°F. Grease a 9-inch springform pan and line the bottom with parchment paper.
02 - In a large bowl, whisk together ricotta cheese, eggs, olive oil or melted butter, vanilla extract, lemon zest, and lemon juice until smooth and well combined.
03 - In a separate bowl, whisk together sugar, flour, baking powder, and salt until evenly distributed.
04 - Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix as this can result in a dense texture.
05 - Pour the batter into the prepared pan and smooth the top. Sprinkle sliced almonds evenly over the surface. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean and the almonds are golden brown.
06 - Allow the cake to cool in the pan for 15 minutes, then release the springform and transfer to a wire rack to cool completely. Dust with coarse sugar or powdered sugar before serving.
