Step‑by‑Step Instructions for Rhubarb Croissant Toast
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (160°C fan forced). While the oven heats up, line a baking tray with parchment paper to prevent sticking and make cleanup effortless. This early preparation ensures a smooth baking process for your rhubarb croissant toast.
Step 2: Prepare the Sugar Syrup
In a medium saucepan, combine caster sugar, water, and orange juice. Bring the mixture to a boil over medium heat, stirring occasionally until the sugar is completely dissolved. Once boiling, remove the saucepan from heat and set it aside to cool slightly, allowing the syrup to thicken just a bit.
Step 3: Make the Frangipane
In a medium bowl, beat together the softened unsalted butter and sugar until the mixture is pale and fluffy, about 5 minutes. Add in the egg, mixing until fully combined. Next, fold in the vanilla bean paste, orange zest, and almond meal until you achieve a thick, smooth texture for your frangipane, which complements the rhubarb wonderfully.
Step 4: Assemble the Toast
Place your stale brioche slices on the prepared baking tray, ensuring they are spaced adequately. Brush half of the prepared sugar syrup over each slice, soaking them slightly without making them too soggy. Next, spread a generous layer of the almond frangipane onto each slice, leaving about a 1cm border around the edges.
Step 5: Add the Toppings
Carefully arrange the sliced rhubarb on top of the almond frangipane, ensuring even coverage. Sprinkle flaked almonds over the rhubarb for added texture and crunch. Finally, brush the remaining sugar syrup on top of the assembled toasts, enhancing their sweetness and ensuring a beautiful glaze once baked.
Step 6: Bake to Perfection
Slide the baking tray into your preheated oven and bake for approximately 40 minutes. Keep an eye on the rhubarb croissant toast, and if the tops begin to brown too quickly, loosely cover them with foil to prevent burning. The toasts are done when they are golden brown and the rhubarb is tender.
Step 7: Serve Warm
Once baked, remove the tray from the oven and let the rhubarb croissant toast cool slightly. To serve, dust with icing sugar for an extra touch of elegance. Enjoy the warm, delightful blend of flavors—perfect with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent finish!

Rhubarb Croissant Toast Recipe FAQs
How do I select ripe rhubarb?
When choosing rhubarb, look for firm stalks with a vibrant color—deep pink or red is ideal. Avoid any that appear wilted or have dark spots, which can indicate overripeness or spoilage. The stalks should snap easily when bent, ensuring they are fresh and crisp.
What’s the best way to store leftover rhubarb croissant toast?
Store any leftovers in an airtight container in the fridge for up to 2 days. For best results when reheating, place the toast in the oven at 180°C (350°F) for about 10 minutes, which helps restore its delightful crispiness and warm, gooey texture.
Can I freeze rhubarb croissant toast?
Absolutely! To freeze, wrap portions of the rhubarb croissant toast tightly in plastic wrap and store in a single layer in the freezer for up to 3 months. When you’re ready to enjoy it, simply thaw overnight in the fridge and reheat in the oven until warm.
What should I do if my frangipane mixture isn’t thick enough?
If your frangipane isn’t thick enough, ensure that the butter is softened properly, as this helps achieve the right consistency when mixed with sugar and almond meal. Adding a bit more almond meal or letting the mixture sit for a few minutes can also help it thicken slightly. Plus, always make sure to beat the mixture for the recommended time to incorporate air effectively.
Can I make rhubarb croissant toast dairy-free or vegan?
Certainly! To make it dairy-free, substitute unsalted butter with margarine, and for a vegan option, use a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water, let sit until thickened) instead of the regular egg. These changes will still yield a delectable rhubarb croissant toast without compromising flavor!
Is this recipe suitable for those with nut allergies?
For those with nut allergies, it’s best to omit the almond meal and flaked almonds altogether, as they are key components of the frangipane and topping. You can use a seed-based alternative like sunflower seed meal to maintain some texture while keeping the dish nut-free.
