Last updated: August 5, 2026
Ingredients
- 1 1/2 cups all-purpose flour
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/2 tsp salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 2 tsp pure vanilla extract
- 3/4 cup buttermilk, room temperature
- 1 cup unsalted butter, softened, for frosting
- 3 cups powdered sugar, for frosting
- 2 tbsp buttermilk, for frosting
Instructions
Preheat oven to 350°F. Line a 12-cup muffin pan with paper liners.
Whisk flour, baking powder, baking soda, and salt in a bowl. Set aside.
Beat 1/2 cup butter and granulated sugar until light and fluffy, about 3 minutes.
Add eggs one at a time, beating well after each. Mix in vanilla.
Add flour mixture in three parts, alternating with buttermilk. Start and end with flour.
Mix just until combined. Do not overmix or the crumb will get tough.
Divide batter evenly among liners, filling each about two-thirds full.
Bake 16 to 18 minutes, until a toothpick comes out clean.
Cool cupcakes in the pan 5 minutes, then move to a wire rack to cool fully.
Beat 1 cup butter until smooth, then add powdered sugar and 2 tbsp buttermilk. Whip until fluffy and pipe onto cooled cupcakes.
Pro Tips
- • Use real buttermilk, not a milk and vinegar swap, for the best tender crumb.
- • Room temperature eggs and buttermilk blend smoother and rise more evenly.
- • Weigh your flour or spoon it into the cup and level it. Packed flour makes dense cupcakes.
- • Let cupcakes cool completely before frosting so the buttercream does not melt.

Final Thoughts
I tested these buttermilk cupcakes in my home kitchen until the crumb matched my favorite bakery. Simple ingredients, a gentle mixing method, and real buttermilk make all the difference.
Frequently Asked Questions
Why do buttermilk cupcakes have a softer crumb than regular cupcakes?
Buttermilk is acidic, which weakens gluten strands as the batter mixes. That gives you a softer, more tender bite compared to cupcakes made with regular milk.
Can I substitute buttermilk in this recipe?
Yes, mix 3/4 cup milk with 2 1/4 tsp lemon juice or white vinegar and let it sit 5 minutes. The texture will be close but real buttermilk still gives a better crumb.
Why did my buttermilk cupcakes sink in the middle?
Sinking usually means underbaking or opening the oven door too early. Test with a toothpick at 16 minutes and add time in 1 minute increments if needed.
How long do these cupcakes stay fresh?
Store unfrosted cupcakes at room temperature in an airtight container for up to 2 days. Frosted cupcakes keep well in the fridge for up to 4 days.
