Grab a medium-sized bowl and combine all the dry ingredients. Sift the flour, cardamom, baking powder, baking soda, and salt to ensure there are no lumps.

Use a whisk and gently stir the mixture until it looks smooth.

In another mixing bowl, add the softened butter and sugar. Beat the ingredients on medium-high speed using a hand mixer until the mixture becomes light and fluffy.

Add one egg at a time and beat after each addition.

Pour milk and vanilla essence into the batter and mix gently until combined.

Add the dry ingredients into the wet mixture in 2 parts and stir until they are fully mixed.

Pour the cake batter into the prepared pan and smooth the top with a spatula.

Grease and line an 8-inch round pan with butter, line the bottom with parchment paper, and dust the sides with flour to prevent sticking.

Bake the cardamom cake in a preheated oven at 350 degrees Fahrenheit or 175 degrees Celsius for 30-35 minutes or until a toothpick inserted into the center comes out clean.

Once baked, let the cake cool to room temperature. Carefully transfer the cake onto a serving plate and dust the top with powdered sugar and pistachios for decoration.

Serve a slice and enjoy every bite of this delicious cardamom cake!
