In a large mixing bowl, combine the egg, milk, sour cream, and oil. Whisk the ingredients together until smooth.
Add the flour, brown sugar, baking powder, baking soda, and salt. Stir gently to combine. It’s okay if the batter has a few lumps—overmixing can lead to dense pancakes.
To give your pancakes a festive touch, stir in a few drops of red or pink food coloring until the batter reaches your desired color. For a natural alternative, you can use beet juice or strawberry puree.
Heat a non-stick or cast-iron pan over medium heat and melt a small amount of butter. Pour about 1/3 cup of batter onto the pan for each pancake. For heart-shaped pancakes, use a greased heart-shaped cookie cutter as a mold. Cook until bubbles form on the surface, then flip and cook for another minute or two until golden brown. You can also cut the heart shape out of the center of a round pancake if you have trouble with the cookie cutters.
Place cooked pancakes on a plate covered with a clean kitchen towel or in a low-temperature oven to keep them warm while you cook the remaining batter.
