In a large bowl, cream the butter and sugar together with an electric mixer until pale and fluffy. With the mixer on medium speed, add one egg at a time until combined. Then, slowly add flour until combined. Divide mixture into two mini loaf pans (5-1/2” x 3” x 2-1/2”) and sprinkle the tops with a little extra sugar (optional). Bake at 350 degrees for 1 hour. Cool for 15 minutes then turn loaves out onto wire racks to cool completely. Serve with Meyer Lemon Marmalade.
