Whisk butter, powdered sugar and vanilla extract until creamy. Finely chop the candied lemon peel. Grate the zest of 2 lemons (set aside approx. 2 tsp for decorating) and extract the juice of 1.
Add eggs, flour, baking powder, almonds and milk to the butter. Add candied lemon peel, lemon zest and juice and a few drops of lemon aroma as well and whisk together. Preheat the oven to 180 °C.
Grease a bundt pan and dust with flour. Pour the batter into the bundt pan and bake for approx. 45 minutes. Decorate with powdered sugar and lemon zest.
Tipps
You can omit the candied lemon peel and just use lemon zest instead, but the candied lemon peel gives a very slight bitter-sweet flavor to the cake.
