Step-by-Step Instructions
1. Make the Blackberry Reduction
- In a saucepan, combine blackberries, sugar, and a splash of water.
- Simmer over medium heat until berries break down.
- Strain through a fine-mesh sieve to remove seeds.
- Let the syrup cool completely.
2. Prepare the Cupcake Batter
- Preheat your oven to 350°F and line a muffin tin with cupcake liners.
- In a bowl, whisk together flour, baking powder, and salt.
- In a separate bowl, beat butter and sugar until fluffy.
- Add eggs one at a time, then mix in vanilla.
- Alternately add dry ingredients and milk, mixing just until combined.
- Stir in the blackberry reduction and bourbon.
- Divide the batter among the cupcake liners.

3. Bake the Cupcakes
- Bake for 18-22 minutes until a toothpick inserted comes out clean.
- Let cupcakes cool completely before frosting.
4. Make the Bourbon Buttercream Frosting
- Beat butter until creamy.
- Gradually add powdered sugar, beating until smooth.
- Mix in bourbon, heavy cream, and a bit of blackberry reduction for color.
- Frost cooled cupcakes generously.

Tips for Success
- Use fresh blackberries – They provide the best flavor and natural tartness.
- Don’t overmix the batter – Overmixing leads to dense cupcakes.
- Let cupcakes cool completely – Warm cupcakes will melt the frosting.
- Adjust bourbon quantity – Add more for a stronger flavor or reduce for a milder taste.

Common Mistakes and How to Avoid Them
- Skipping the reduction step – This intensifies the blackberry flavor. Don’t rush it.
- Overbaking – Check early to prevent dryness.
- Too much liquid in frosting – Add powdered sugar if it gets too runny.
Variations to Try
- Non-Alcoholic Version – Replace bourbon with vanilla extract.
- Chocolate Blackberry Cupcakes – Add 1/4 cup cocoa powder to the batter.
- Lemon Blackberry Cupcakes – Swap bourbon for lemon juice and zest.
