Some memories aren’t just in your head; you can taste them. For me, that taste is my dad’s Boston Cream Cupcakes.
He wasn’t a fancy baker. He was a guy who knew that a little bit of homemade goodness could solve just about anything. A bad day at school, a scraped knee, or just a Tuesday that felt a little too long.
He’d pull out his worn, stained recipe card, and the kitchen would start to smell like vanilla, sugar, and comfort. These cupcakes are more than just a dessert. They’re a hug in a paper liner.
I’ve tweaked his recipe just a tiny bit over the years, but the soul of it is all his. Now, I get to share that little piece of my childhood with you. Let’s make something special.
What You’ll Need
I’ve broken this down into the three magical components: the fluffy cupcakes, the creamy filling, and that shiny chocolate top. Don’t let the list intimidate you; it’s mostly pantry staples.
For the Vanilla Cupcakes:
- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- 1 ½ teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, softened to room temperature
- 2 large eggs, room temperature
- ½ cup whole milk, room temperature
- 2 teaspoons vanilla extract
For the Pastry Cream Filling:
- 1 ½ cups whole milk
- ½ cup granulated sugar
- ¼ cup cornstarch
- ⅛ teaspoon salt
- 4 large egg yolks
- 2 tablespoons unsalted butter, cold
- 1 ½ teaspoons vanilla extract
For the Chocolate Ganache:
- 4 ounces semi-sweet chocolate, finely chopped
- ½ cup heavy cream
Pro Tips for Perfect Cupcakes
Over the years, I’ve learned a few things (mostly by messing up). Here are the secrets to getting these cupcakes just right on your first try.
- Strain That Cream: No matter how well you whisk, tiny cooked bits of egg can find their way into your pastry cream. For a perfectly silky, smooth texture, always pour the finished cream through a fine-mesh sieve. It’s a non-negotiable step in my book.
- The Room Temperature Rule: I know, it’s tempting to pull your butter and eggs straight from the fridge. Don’t do it. Room temperature ingredients emulsify better, creating a lighter, fluffier cupcake crumb. It makes a huge difference.
- The Ganache Dip: Instead of trying to spread the ganache with a knife, which can get messy, just hold the filled cupcake upside down and dip the top straight into the bowl of ganache. Give it a gentle twist as you pull it out for a clean, professional finish.
- Don’t Fear the Yolk: The pastry cream gets its rich flavor and color from the egg yolks. Don’t be shy with them. Save the egg whites for an omelet tomorrow morning!

How to Make Daddy’s Boston Cream Cupcakes
Let’s get baking. Follow these steps, and you’ll be golden. I suggest making the pastry cream first so it has time to chill completely.
Part 1: The Pastry Cream
Step 1: In a medium saucepan, heat 1 ¼ cups of the whole milk over medium heat until it just begins to simmer. Don’t let it boil.
Step 2: While the milk is heating, whisk the egg yolks, sugar, cornstarch, and salt together in a separate bowl until pale and smooth. Whisk in the remaining ¼ cup of cold milk.
Step 3: Slowly pour about half of the hot milk into the egg yolk mixture, whisking constantly. This is called tempering and it prevents the eggs from scrambling.
Step 4: Pour the tempered egg mixture back into the saucepan with the rest of the milk. Cook over medium heat, whisking constantly, until the cream thickens and starts to bubble. This takes about 2-3 minutes.
Step 5: Remove from the heat and immediately strain through a fine-mesh sieve into a clean bowl. Whisk in the cold butter and vanilla extract until smooth.
Step 6: Press a piece of plastic wrap directly onto the surface of the cream to prevent a skin from forming. Refrigerate for at least 2 hours, or until completely cold.
Part 2: The Vanilla Cupcakes
Step 1: Preheat your oven to 350°F (175°C) and line a muffin tin with 12 cupcake liners.
Step 2: In a medium bowl, whisk together the flour, baking powder, and salt.
Step 3: In a larger bowl, use an electric mixer to beat the softened butter and sugar together until light and fluffy, about 3-4 minutes.
Step 4: Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
Step 5: Add half of the dry ingredients to the butter mixture, mixing on low until just combined. Then, add all of the milk and mix until combined. Finish by adding the remaining dry ingredients, mixing only until no streaks of flour remain. Do not overmix!
Step 6: Fill each cupcake liner about two-thirds full. Bake for 20-22 minutes, or until a toothpick inserted into the center comes out clean.
Step 7: Let the cupcakes cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
Part 3: The Ganache & Assembly
Step 1: Once the cupcakes are cool and the pastry cream is chilled, make the ganache. Place the chopped chocolate in a heatproof bowl.
Step 2: Heat the heavy cream in a small saucepan or in the microwave until it’s simmering. Pour the hot cream over the chocolate and let it sit for 5 minutes without stirring.
Step 3: Whisk the mixture gently until the ganache is smooth, shiny, and completely combined. Let it cool slightly for 10-15 minutes to thicken up a bit.
Step 4: While the ganache cools, fill the cupcakes. Use a small knife or an apple corer to remove a small cone from the center of each cupcake. Don’t go all the way to the bottom.
Step 5: Fill a piping bag (or a Ziploc with the corner snipped off) with the chilled pastry cream. Pipe the cream into the cored-out center of each cupcake.
Step 6: Dip the top of each filled cupcake into the ganache. Place them back on the rack and refrigerate for about 15-20 minutes to allow the ganache to set.
Substitutions and Variations
Don’t have something on hand? No problem. Baking should be flexible.
| Original | Substitution | Note |
|---|---|---|
| Whole Milk | 2% Milk | Cream will be less rich. |
| All-Purpose Flour | Cake Flour | Use 1 ¾ cups for a finer crumb. |
| Semi-Sweet Chocolate | Dark or Milk Chocolate | Adjusts sweetness of ganache. |
- Make it Mocha: Add a teaspoon of instant espresso powder to the heavy cream when you heat it for the ganache.
- Different Extract: Try a little almond extract in the cupcake batter along with the vanilla for a different flavor note.
- Gluten-Free: You can swap the all-purpose flour for a good quality 1-to-1 gluten-free baking blend.
Healthier Swaps, Pairings, and Efficiency
These are definitely a treat, but you can make a few tweaks. For efficiency, always make the pastry cream while the cupcakes bake and cool.
- Dietary Swaps: For a dairy-free version, use high-quality plant-based butter, unsweetened almond or soy milk, and a dairy-free chocolate. Coconut cream works well for the ganache.
- Sugar Reduction: You can slightly reduce the sugar in the cupcake batter, but I don’t recommend altering it in the pastry cream as it affects the texture.
- Perfect Pairings: These are fantastic with a simple cup of black coffee or a tall glass of cold milk. Nothing fancy is needed.
Make-Ahead, Leftovers and Storage
These cupcakes are best enjoyed fresh, but you can prep parts ahead of time.
The pastry cream can be made up to 2 days in advance and kept in the fridge with plastic wrap on the surface. The cupcakes can be baked a day ahead and stored in an airtight container at room temperature.
Once assembled, the cupcakes must be stored in an airtight container in the refrigerator because of the pastry cream. They will last for up to 3 days, though the cake will be at its best on day one.
Frequently Asked Questions
Q1. Why is my pastry cream lumpy?
Ans: This usually happens for two reasons: the milk was too hot when you tempered the eggs, causing them to scramble slightly, or it wasn’t whisked constantly while cooking. The best fix is prevention: temper slowly and whisk like you mean it! Straining it through a sieve will catch any lumps.
Q2. My ganache is too thick/thin. How do I fix it?
Ans: If it’s too thick, whisk in a teaspoon of warm heavy cream at a time until it reaches the right consistency. If it’s too thin, let it cool longer or add a few more chopped chocolate chips and whisk until melted and smooth.
Q3. Can I freeze these cupcakes?
Ans: I don’t recommend freezing the assembled cupcakes. Pastry cream can separate and become watery when thawed. You can, however, freeze the unfilled, un-glazed cupcakes for up to a month in a freezer-safe bag.
