Preheat your oven to 350°F (175°C) and grease a mini bundt pan.
In a mixing bowl, whisk together flour, baking powder, and salt.
In another bowl, beat softened butter and sugar until light and fluffy (about 3 minutes).
Add eggs one at a time to the mixture, then mix in vanilla extract and lemon zest.
Gradually combine dry ingredients with wet ingredients until just mixed; avoid over-mixing.
Pour batter into the bundt pan (fill two-thirds full) and bake for 20-25 minutes until golden brown.
Let cool before removing from the pan; decorate as desired.
