Boston Cream Croissants

Boston Cream Pie Croissants came about on a gloomy Sunday. I’d promised my kids an awesome breakfast, but totally spaced on prep. All I had were old croissants and some pudding cups hanging out in the fridge. Twenty minutes of mixing things up, and these turned into a huge hit. Now, my family asks for them every time we get together.

My sister-in-law watched me whip these up last month and couldn’t believe how little effort it took. She’s the from-scratch queen, so hearing her grudgingly admit they were “actually amazing” felt pretty awesome on my end.

Tasty Ingredients

• Easy croissants: Snag some from the bakery aisle if you can, or just grab what’s available at the store—anything works in a pinch
• Rich cream: I’ve swapped in heavy cream, half & half, or even plain old milk (richer cream just makes things extra tasty)
• Egg yolks: Keep the whites in the fridge for tomorrow’s omelet—or bake up some meringue cookies if you’re feeling fancy while the custard cools
• Great chocolate: Go for the good stuff if you want, but I’ve definitely tossed in chocolate chips plenty of times and no one complained
• Chopped nuts: Use anything you’ve got lying around—fancy pistachios, or just whatever’s left in the nut jar from last holiday season

Croissant Filling Holes

Jam a chopstick or wooden stick through each croissant—don’t bother making perfect tunnels, just wiggle it around for good space. I used to poke too gently and ended up with barely any filling inside. Now, I really carve those babies out, picking up flaky bits for a snack as I go.

Custard Tricks

Mix your yolks, sugar, cornstarch, and salt until perfectly smooth before pouring in any cream. I once got lazy with this and ended up with icky lumps that drove me nuts. Add cream bit by bit, whisking with all you’ve got. Stand right by the stovetop as the custard thickens—stepping away once landed me with scrambled eggs. Learned my lesson—custard calls the shots!

Butter Step

Toss in butter cubes one at a time, waiting for each to melt. I used to dump them all in at once, mostly when my toddler was wild, and while it melted eventually, the custard never turned out quite as smooth. Add vanilla at the end. Once, I put it in too soon and my lovely custard got all chunky—never again.

Filling Croissants

No piping bag? Use a ziplock and clip the edge, or even a turkey baster if you’re desperate. Squeeze custard from both ends until you feel it push back or spot a leak. I used to overstuff and made a big huge mess—go easy, it saves you from scrubbing your counters later.

Making Ganache

Heat cream just long enough to see tiny bubbles along the edge (don’t boil it!). I used to stir the chocolate too early—now I let it sit, untouched, for a minute, so it melts better. If it ever looks soupy, just let it rest on the counter a few minutes before spooning over the croissants.

Choc Topping & Nuts

Act quickly to spoon on the chocolate before it stiffens. I drop a dollop in the middle, let it run off the sides, and sometimes smooth it out pretending I’m on a TV baking show. Drop nuts on right away for best sticking—wait too long and you’ll be chasing them off your plate, trust me.

Tom from next door, who says he’s not into “fancy desserts,” wolfed down three in one go last summer while dropping off our lawnmower. His wife said he kept calling them “those creamy chocolate things” for days. Sometimes the most stubborn eaters end up being the biggest fans.

Awesome Pairings

Fresh strawberries are amazing with these—they cut through all that richness just right. Gotta have strong black coffee too, especially if you like something bold with your sweets. If I’m serving these after dinner, a tiny glass of Baileys or amaretto goes perfectly with the vanilla inside. My kids? They vote for giant glasses of cold milk. Some classics are classic for a reason.

Fun Mixups

Try almond extract in the custard with toasted almonds on top, the way my mother-in-law loves. At Christmas, I go for peppermint in the chocolate topping and sprinkle on crushed candy canes. Last summer I swapped in lemon zest and white chocolate ganache—everyone said it tasted like a sunny day, and it was gone before anyone could sneak a photo.

Staying Fresh

Honestly, these usually disappear before you need to think about leftovers. But if you want to prep ahead: keep plain croissants in a paper bag at room temp and put custard in the fridge for a couple days. Once filled and topped, these are good in the fridge for about a day before they get too soft. For parties, I make mini ones with tiny croissants—they’re tougher so they last longer after stuffing.

Save

I bring these Boston Cream Pie Croissants everywhere—from book club to school staff breakfasts. They’re my go-to “I want to do something nice, but don’t have hours to spare” move. The best bit is seeing everyone’s reactions on the first bite—it’s never what they expect from a plain croissant. Even my picky cousin (the one who studied pastry in France) admitted, “not bad at all”—which, in family speak, means totally delicious.

Recipe FAQs

→ Can I prep these the day before?

Totally. Just store them in the fridge, sealed tightly so the croissants stay nice and fresh.

→ Can I swap custard for instant pudding?

Sure, pudding works if you're in a rush, but making your own custard gives it a richer feel and flavor.

→ What’s the right texture for custard?

It’s good to go when it coats a spoon. Drag your finger through it—if the line stays clear, it’s ready.

→ Will older croissants work?

Yes! Day-old ones are actually great since they hold their shape better after stuffing.

→ What if I have no piping bag?

Use a plastic bag, snip off the corner, or carefully spoon the custard in. Both options work just fine.
