Preheat the oven: Start by preheating your oven to 350°F (175°C). Prepare a cookie sheet by lining it with parchment paper or a silicone baking mat.
Cream butter and sugar: In a large mixing bowl, cream together 3/4 cup softened butter and 1 cup brown sugar until the mixture is light and fluffy. This process usually takes about 2-3 minutes.
Add egg and molasses: Next, incorporate 1 egg and 1/4 cup molasses into the creamed mixture. Mix until everything is well combined.
Stir in dry ingredients: Gradually mix in the dry ingredients: 1 tsp ginger, 1 tsp cinnamon, 2 tsp baking soda, 1/4 tsp salt, and 2 1/4 cups flour. Stir until just combined; do not overmix to keep the cookies tender.
Form cookie dough balls: With your hands, form small balls of dough (about 1 tablespoon in size). Roll each ball in sugar for added sweetness and a sparkling finish, then place them onto the prepared cookie sheet.
Bake the cookies: Bake in the preheated oven for 8-9 minutes, or until the cookies are puffed and slightly golden. They may look a little underbaked; don’t worry—they will firm up as they cool.
