Preheat the oven to 300°F/150°C. Then generously grease a tube cake pan with cooking spray. Set aside.
Then, in a stand or hand mixer, cream the butter and sugar at high speed until it’s fluffy and starts to look white, 5-7 minutes.
Stir in the eggs, one at a time, beating the mixture well between each addition.
Mix in flour, baking powder, and salt into the batter.
Follow with the buttermilk and vanilla extract. (You can add the optional almond extract and lemon zest here, too.) Stir well until everything is thoroughly combined, scraping the sides of the bowl down as you go. Do NOT over mix.
Pour the pound cake batter into the greased cake pan. Tap pans on your work surface to eliminate any large air bubbles.
Bake at 300°F/150°C until a tester inserted into the center comes out clean, 55-60 minutes or more.
Transfer the pound cake to a wire cooling rack, dust with powdered sugar, serve with fresh fruits and whipped cream.
Enjoy!!!
