In a medium bowl, combine the yogurt, water, eggs, pumpkin, oil and vanilla. In another medium bowl, combine the flour, brown sugar, sucralose, baking powder, cinnamon and salt. Slowly add the wet ingredients to the dry ingredients and whisk until well-incorporated.
Heat a nonstick saute pan over medium heat and lightly coat the pan with cooking spray. Pour 1/4 cup of the batter into the pan. Cook the pancake for approximately 2 minutes or until the top surface is bubbly and the edges are slightly brown. Flip the pancake using a spatula and cook for another 2 to 3 minutes. Repeat this process until all of the pancake batter is used.
