Why I Love This Recipe

- Rich pastry cream: Smooth, creamy, and just sweet enough to balance the cake and chocolate.
- Accessible ingredients: No specialty items required—most are pantry staples.
Ingredient Notes & Shopping Tips

- Butter: Use softened (not melted) butter. It should give slightly when pressed with a finger.
- Eggs: Bring eggs to room temperature so the batter emulsifies smoothly.
- Flour: Spoon flour into the measuring cup and level with a knife to avoid packing, which can make cupcakes dry.
- Milk: Whole milk gives the best texture for the pastry cream; low-fat or plant milks will change the result.
- Baking powder: Replace every 6–12 months for reliable rise.
- Buttermilk: If you don’t have it, make a quick substitute by adding 1 tablespoon of vinegar or lemon juice to 1 cup of milk and letting it sit for a few minutes.
Short On Time?
Use a boxed yellow cake mix and substitute instant vanilla pudding or store-bought vanilla pudding for the homemade pastry cream to save time.
How to Make Boston Cream Cupcakes

- Make the cupcakes: Cream butter and sugar until light. Add eggs and vanilla, then alternate adding flour and buttermilk until just combined.
- Bake: Fill liners about 2/3–3/4 full and bake at 350°F for 18–23 minutes, until a toothpick shows a few moist crumbs.
- Make the pastry cream: Whisk egg yolks with milk. Heat sugar, cornstarch, and salt, gradually whisk in the milk mixture, and boil, stirring, for 1 minute. Remove from heat and cool in an ice bath before adding vanilla.
- Make the ganache: Heat heavy cream to a simmer, pour over chocolate chips, cover 5 minutes, then stir until smooth. Let it cool until it thickens slightly so it will coat the cupcakes without running off.
- Assemble: Core each cupcake, pipe or spoon in pastry cream, then dip the top into ganache or spoon ganache over the top. Allow ganache to set for 30–60 minutes.
FAQS
You can bake the cupcakes up to 2 days in advance; fill them with pastry cream and top with ganache on the day you plan to serve them for best texture.
An apple corer works well. You can also use a small knife or a piping tip to remove the center.

Tips
- Use room-temperature ingredients: This ensures an even, lump-free batter and smooth pastry cream.
- Don’t overmix the batter: Overmixing develops gluten and yields dense cupcakes.
- Use an ice bath for the pastry cream: Cooling quickly stops cooking and prevents a skin from forming.
- Portion batter consistently: An ice cream scoop helps fill pans evenly—fill about 2/3 full.
- Watch baking time: Remove cupcakes when a toothpick shows a few moist crumbs to avoid drying them out.
- Cool ganache slightly before dipping: Let it thicken for about 10 minutes until it mounds slightly when drizzled.
Cool Your Ganache
Let ganache cool about 10 minutes until it thickens slightly. It should mound a bit when drizzled so it stays on the cupcake instead of running off.
