  • 4 Tbsp. Bird’s Original Custard Powder (Not the instant Bird’s Custard mix, it contains whey)

To Make the Crust!

Start by taking your flour, sugar, and salt and mixing them up in a mixing bowl. Then cut up your cold vegan butter into tiny cubes and add them into the mixing bowl along with your cold water. (It’s crucial that the butter and water are cold!

Next, you can either use your hands to mix everything up or use a food processor. I like using my hands to mix everything up, but a food processor might be quicker.

Mix up all the ingredients well until you start getting a dough. You’re going to want to make the dough into a nice, smooth ball. The dough should feel a little dry (That’s what will give your crust a flakey texture), but if it’s too dry to form a solid ball, you can keep adding very small amounts of cold water until everything starts sticking together better.

Once your dough ball is formed, wrap it in plastic wrap and stick it in the fridge for 10-15 minutes.
While you’re waiting for your dough, pre-heat your oven to 400 degrees.

Next, take out your tart baking dish, a rolling pin, and some extra flour.
Scatter some of the flour onto a flat surface to place your dough ball on. After your dough has been chilled, unwrap and place on the floured surface.

Press down and start rolling the dough out, starting from the middle and evenly rolling out until it’s flat in a nice rounded shape. You can also use some cold water to patch up any areas that look dry or are cracking; make sure that your rolling pin has flour on it to prevent the dough from sticking. Your dough should be no more than a centimeter in thickness.

After you have your dough rolled out, place it gently and evenly over the tart dish. Start to knead the dough into place so that it fits the baking dish. Cut off any extra dough hanging off of the side. Keep about a centimeter of dough hanging over so you can create the wavy pattern. I like to use my thumb to press into the indents inside the dish and use my index finger on the outside divets to create that wavy tart crust. I follow the shape of the dish.

Once everything is in place, pierce the bottom of the dough with a fork to let air flow while it’s baking. (This will keep the crust flesh to the dish while in the oven)
Place foil over the whole dish and pop in the oven for 15 minutes.

After 15 minutes, remove the foil and brush vegan butter over the edges of the crust (this will give it gently browned edges when it’s done baking), then return the dish into the oven (without foil) and bake for another 15 minutes.

While the crust is baking, start on the custard filling.
To start, get a saucepan and mix the custard powder, sugar, and 2 tbsp of oat milk (take from the 2 1/3 cups) and mix until you get a paste.
After those are mixed up into a paste, add the rest of the oat milk. Turn on the stove to medium heat and heat.

While the custard is heating up, mix the corn starch with 1tbsp of cold water until it turns into a cloudy liquid/paste. Then add the cornstarch mix into the custard. (The cornstarch will help thicken the custard so that it has form in the tart) Keep stirring the custard mix until you can see it’s thickening and bubbling. You can take the custard off of the stove once you see it boiling with the bubbles. Remember to stir continuously, so you prevent a film from forming on the top of the custard.

Once your crust is all baked, you can place it in the fridge to cool down a bit, but it’s not necessary. I like to do this for about 5-10 minutes while stirring the custard off the stove to avoid forming a film. You want to keep it smooth before pouring.

Now add the custard filling into the crust. I like to use a spoon to make sure it’s nice and smooth, and evenly distributed. Make sure to bring the custard up around the edges of the crust, and it should settle nicely into the grooves.

Refrigerate the custard tart for about 3-4 hours, and this will make it set. The custard will have a creamy-jello-like texture and will take shape while cooling.

When it’s almost time for you to take the tart out of the fridge, start cleaning your berries, and chop your strawberries into your desired shape for the topping, you can get creative!
Once your topping is in place, you’re all set! Keep this refrigerated when not serving.

Last but not least, enjoy!
