Lower the oven rack to the next to lowest position.
Preheat the oven to 325 degrees. Grease and flour a 10 cup bundt pan or tube pan.
In a separate bowl, add the flour, salt, baking powder, and lemon zest whisk to blend. Set aside.
Mix the butter until smooth, gradually add the sugar and mix on medium speed 3 to 5 minutes or until the mixture is lightened in color and fluffy.
Add the eggs one at a time beating after each until the yellow of the yolk disappears. Scrape the bottom and sides of the bowl several times.
Add the lemon extract to the 1 ¼ cup heavy cream.
With the mixer on low speed, add the flour mixture alternately with milk, beginning and ending with flour mixture. After each addition, mix just until blended. Be careful not to overmix or mix at a high speed.
Fold in the coconut -- the cake batter will be quite thick
Spoon batter into greased and floured bundt or 10 inch tube pan. The oven temperature is 325 degrees F. Our cake baked for 1 hour, 30 minutes. Baking times may vary depending on your pan, oven, etc. It's best to peek in at least by the 1 hour, 10 minute mark to be on the safe side. Cover loosely with aluminum foil if the top becomes too brown.
The cake is done when a wooden skewer inserted into the cake comes out clean or with just a few crumbs attached. Let cool on a wire rack for 10 minutes then remove from pan.
If refrigerating or freezing this cake, it must be completely at room temperature when serving for best texture and flavor.
