preheat oven to 350°F, grease pan and set aside. for some reason when I also flour the pan I have a heck of a time getting it out, so I don't. You do you
making the cake
sift the flour salt and baking soda together into a bowl. set aside
add the sugar and butter to mixing bowl, beat on medium till fluffy 8-10 minutes. Add eggs, one at a time, beating well after each addition. Add the flour mixture in 3 batches, alternating with the buttermilk. beating well after each addition and ending with the flour. Stir in the lemon extract and juice.
Place in the pre-heated oven and immediately lower the oven temp to 325°F. Bake until a toothpick inserted into the center comes out clean, 60-75 minutes.
remove and cool in the pan for about 10 minutes. Take the cake out of the pan, tapping, shaking however you can get it out. Place on a wire rack and over parchment.
making the glaze
beat the confectioners sugar, lemon juice, butter and lemon zest in a bowl with an electric mixer. I used a fork and stirred vigorously.
pour about ½ the glaze over the warm cake. Let it cool for 20 minutes, pour the remaining glaze over the top.
