INGREDIENTS
- 1 ½ cups all-purpose flour
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs
- 1 tsp pure vanilla extract
- ½ cup sour cream (or plain yogurt)
- ¼ cup milk (any kind)
Optional Topping:
- 2 tbsp sugar + ½ tsp ground cinnamon for sprinkling
Instructions
- Preheat oven to 350°F (175°C). Grease and flour an 8×8-inch baking pan or line it with parchment paper.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In a large bowl, beat the butter and sugar together until light and fluffy (about 2-3 minutes).
- Add the eggs one at a time, mixing well after each. Stir in the vanilla extract.
- Mix in the sour cream until smooth.
- Gradually add the dry ingredients, alternating with the milk. Begin and end with the dry ingredients. Mix just until combined—do not overmix.
- Pour batter into the prepared pan and smooth the top with a spatula.
- If using, sprinkle the cinnamon-sugar topping evenly over the batter.
- Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
- Cool in the pan for 10–15 minutes, then slice and serve warm or at room temperature.
