This version of French toast made into muffin cups was an instant hit the first time I made it for a weekend brunch. I discovered it on a sleepy Sunday when I had a stack of leftover croissants and wanted a way to turn them into something special that would travel well to a potluck. The result is tender, custardy interiors with crisp, caramelized edges and a buttery streusel that adds a satisfying crunch. The aroma of vanilla, cinnamon and warm croissant is what gets everyone out of bed—and seconds are always requested.

I love this adaptation because it takes a classic comfort-food flavor and turns it into neat, individual portions that are easy to serve, freeze, and reheat. The croissant gives a flakier, richer texture than standard bread—think layers of buttery pillows that soak up the egg-milk mixture but still keep a little structure. It’s forgiving, quick to pull together, and always looks elegant on a brunch spread. I first made these for a holiday brunch where they disappeared in minutes; since then I’ve tweaked the streusel and custard ratios until they’re reliably perfect.

Ingredients

• Milk (1 1/2 cups): Use whole milk for the richest custard; 2% works well too. If you want a slightly richer result, substitute 1/2 cup of the milk with half-and-half.
• Granulated sugar (2 tablespoons): Balances the custard sweetness without overwhelming the croissant’s buttery notes. Brown sugar may be used for a deeper flavor, but I prefer granulated here to keep the custard light.
• Eggs (5 large): Eggs set the custard and give structure—use large eggs at room temperature so they blend more evenly.
• Vanilla extract (2 teaspoons): Pure vanilla adds warm floral notes; use good-quality extract for the best flavor uplift.
• Cinnamon (1 teaspoon) and Nutmeg (1/2 teaspoon): Lightly spiced custard complements the streusel. Freshly grated nutmeg makes a lovely difference if available.
• Cubed croissants (about 8 cups): Day-old or slightly stale croissants are ideal because they soak up custard without collapsing. If you can, tear into rough 1-inch pieces for varied texture.
• Maple syrup and powdered sugar: For serving—pure maple syrup is my pick; powdered sugar is optional for an elegant finish.
• Streusel topping: 4 tablespoons cold unsalted butter, 1/4 cup packed brown sugar, 1/4 cup all-purpose flour, 1/2 teaspoon ground cinnamon. Keep the butter cold so the crumbs stay flaky and crisp after baking.

Instructions

Preheat and prepare the pan: Preheat the oven to 350°F. Spray a 12-cup muffin tin with nonstick spray or brush each cup lightly with melted butter to ensure easy release. Preparing the pan ahead keeps the bottoms of the cups from sticking and encourages even browning. Whisk the custard: In a large mixing bowl, whisk together 1 1/2 cups milk, 2 tablespoons granulated sugar, 5 large eggs, 2 teaspoons vanilla extract, 1 teaspoon ground cinnamon, and 1/2 teaspoon ground nutmeg until thoroughly combined and slightly frothy. Room-temperature eggs incorporate more smoothly and give a more uniform set to the custard. Toss the croissant cubes: Add about 8 cups of cubed croissants to the custard mixture and toss gently until pieces are evenly coated. Let sit for 2–3 minutes so the croissant layers start to take on custard—don’t wait too long or they will become mushy. Fill the muffin tin: Divide the croissant-custard mixture evenly among the 12 muffin cups, pressing pieces lightly so each cup is well packed but not overflowing. Pour any remaining custard over the tops so each cup has enough moisture for a custardy center. Make the streusel: In a small bowl, combine 1/4 cup packed brown sugar, 1/4 cup all-purpose flour, 1/2 teaspoon ground cinnamon and 4 tablespoons cold, cubed butter. Use a fork or your fingertips to rub in the butter until the mixture forms coarse crumbs. The goal is pea-sized crumbs that will crisp up in the oven. Top and bake: Spoon the crumbly streusel evenly over each filled cup and gently press so crumbs adhere. Bake at 350°F for 25–28 minutes until the tops are golden brown and a toothpick inserted into the center comes out mostly clean with a few moist crumbs. Rotate the pan halfway through for even color. Finish and serve: Allow the cups to cool in the pan for 5–7 minutes, then transfer to a wire rack. Serve warm with pure maple syrup and a dusting of powdered sugar if desired. These are best enjoyed the day they’re baked but keep well in the fridge for quick reheating.

Storage Tips

Store cooled muffin cups in an airtight container in the refrigerator for up to 3 days. For longer storage, wrap each muffin cup individually in plastic wrap then place into a freezer-safe bag for up to 3 months. To reheat from frozen, thaw overnight in the refrigerator and warm at 325°F for 8–12 minutes, or microwave on medium power for 45–60 seconds until heated through. Use a shallow baking dish and cover loosely with foil when reheating in the oven to maintain moisture.

Ingredient Substitutions

If you don’t have croissants, cubed brioche or challah are excellent swaps and will produce a similar richness; regular white sandwich bread works in a pinch but will be slightly less decadent. For dairy-free options, use a nut milk like unsweetened almond or oat milk plus a dairy-free butter substitute in the streusel; the texture will be a touch different but still delicious. To reduce sweetness, cut back the granulated sugar to 1 tablespoon and use a less-sweet streusel.

Serving Suggestions

Serve warm with pure maple syrup, a light dusting of powdered sugar, or a dollop of mascarpone or Greek yogurt to cut the richness. For a brunch spread, pair with fresh fruit—berries or sliced stone fruit work beautifully—or a simple arugula salad with lemon vinaigrette to balance the sweetness. Garnish with toasted pecans or sliced almonds for extra crunch and an elegant touch when entertaining.

Cultural Background

Cinnamon-battered bread dishes have roots across many regions—French toast itself is known as "pain perdu" in France, literally translated as "lost bread," a practical way to rescue stale loafs. This individual-cup adaptation brings a modern, American brunch sensibility to the classic: croissants are a French bakery staple, but turning them into muffin cups reflects a trend toward portable, shareable brunch items popular in cafés and home entertaining. The streusel topping echoes Central European crumb-topped pastries, creating a hybrid that tastes familiar across traditions.

Seasonal Adaptations

Adjust the toppings and mix-ins by season: in fall, fold in thinly sliced apples or pear with a pinch of cardamom; in summer, stir in halved blueberries or raspberries and top with lemon zest. For winter holidays, add a tablespoon of orange zest to the custard and swap half the cinnamon for ground ginger for a festive note. These small tweaks transform the base into a seasonal showpiece.

Meal Prep Tips

For make-ahead convenience, assemble the filled muffin tin, cover tightly with plastic wrap and refrigerate for up to 12 hours before baking—this is perfect for holiday mornings. If freezing, place the unbaked cups on a baking sheet until firm, then transfer to a freezer-safe container; bake from frozen adding an extra 6–8 minutes to the baking time. Label containers with bake date and contents for easy meal planning.

Success Stories

Readers and friends have told me this is their new holiday secret: one family made a double batch for Christmas morning and used the leftovers for breakfast-for-dinner the next week, praising how simple it was to reheat. I once brought a tray to a neighborhood brunch and someone asked for the recipe after the second helping—that’s the moment I knew it had a permanent place in my repertoire. Little hands and adult taste testers alike love the crunchy streusel on top.

These croissant French toast cups are a delightful, versatile dish that elevates simple ingredients into something memorable. Whether you’re feeding a crowd or prepping weekday breakfasts, they’re forgiving, flavorful and adaptable—make them your own with seasonal fruits, spice blends, or a swap of bread. Enjoy the warm, buttery goodness and the smiles they bring to the table.
