Why I Love This Recipe
- Perfect vanilla cupcakes: The batter yields moist cupcakes with a tender crumb every time.
- Luxurious pastry cream: Smooth, rich, and just sweet enough—perfect for filling.
- Simple ingredients: No specialty items required; most are pantry staples.
Ingredient Notes / Shopping Tips
- Butter: Use softened (not melted) unsalted butter. It should give slightly when pressed.
- Eggs: Bring eggs to room temperature so the batter emulsifies smoothly.
- Flour: Spoon and level flour when measuring to avoid dense, dry cupcakes.
- Milk: Whole milk gives the best texture for the pastry cream; low-fat and many non-dairy alternatives will change the result.
- Baking powder: Fresh baking powder (replaced every 6–12 months) helps the cupcakes rise properly.
- Buttermilk: If you don’t have buttermilk, make a substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for a few minutes.
Short On Time?
You can streamline this recipe by using a boxed yellow cake mix and instant vanilla pudding instead of making pastry cream from scratch. The result won’t be identical, but it’s an easy shortcut that still delivers great flavor.
How to Make Boston Cream Cupcakes
- Make the cupcakes: Cream butter and sugar until light. Add eggs and vanilla, then fold in dry ingredients alternating with buttermilk until just combined.
- Bake: Fill liners about 2/3–3/4 full and bake at 350°F for roughly 18–23 minutes, until a toothpick comes out with a few moist crumbs.
- Make the pastry cream: Whisk egg yolks and milk. In a saucepan, combine sugar, cornstarch, and salt; gradually whisk in the milk mixture, bring to a boil while stirring, and cook 1 minute until thickened. Cool in an ice bath and stir in vanilla.
- Make the ganache: Heat heavy cream until it just simmers, pour over chocolate chips, let sit 5 minutes, then stir until smooth and glossy. Let the ganache cool slightly so it thickens enough to coat the cupcakes without running off.
- Assemble: Core each cooled cupcake, pipe or spoon in the pastry cream, then dip the tops into the ganache. Let set 30–60 minutes before serving.
FAQS
Yes. Bake cupcakes up to two days ahead and store them airtight. Prepare the pastry cream and ganache the day you plan to serve and assemble shortly before enjoying for the best texture.
An apple corer works well. You can also use a small sharp knife or a piping tip to remove the center before filling.
Tips
- Use room-temperature ingredients: They combine more easily and yield a smoother batter.
- Don’t overmix: Overworking the batter develops gluten and yields dense cupcakes.
- Use an ice bath for the pastry cream: Cooling quickly prevents overcooking and stops a skin from forming.
- Portion batter with an ice-cream scoop: It creates even cupcakes; fill liners two-thirds to three-quarters full.
- Avoid overbaking: Remove cupcakes when a toothpick shows a few moist crumbs for a tender crumb.
- Cool ganache before dipping: Let the ganache thicken about 10 minutes so it coats the cupcakes and sets with a glossy finish.
