Feeling the inflation pinch? There’s a new vegan cookbook that might capture your attention. BOSH! on a Budget was released this summer, and it boasts more than 100 recipes that use time-tested tricks to help you save money. The options range from hearty weeknight dinners to celebration-worthy sweets, like this vegan lemon cake. It’s a British-style tray cake that’s layered with sweet and tangy citrus.
This Vegan Lemon Cake is a British Favorite on a Budget
Henry Firth and Ian Theasby are the bestselling vegan cookbook authors behind the BOSH! book series. BOSH! on a Budget is their latest collection, with a range of comfort food like General Tso’s Tofu, Mushroom Stroganoff, Big-Batch Bolognese, Salted Caramel Sticky Toffee Pudding, and this amazingly Lemon Drizzle Traycake. It looks fancy, but uses less than 10 ingredients and is, indeed, quite cheap to make.
What Other Pan Sizes Can I Use?
The authors are British, so the pan sizes they use aren’t always standard options in North America. But you can use an 8×8-inch square baking dish or a 9-inch round cake pan. You can also double the recipe and bake it in a 9×13-inch baking dish, or make a two layer cake with the 9-inch round cake pans.
How Can I Substitute the Self-Rising Flour?
If you don’t have any self-rising flour on hand. Simply whisk 2 cups + 3 tablespoons all-purpose flour with 1 tablespoon baking powder and 1/2 teaspoon salt. Use this in place of the self-rising flour in this vegan lemon cake recipe.
Do I Have to Use Oat Milk?
No, you can use your favorite dairy-free milk beverage for baking. The authors just prefer to bake with oat milk. But most types will work just fine. I would choose a plain or unsweetened flavor.
What Other Oils Can I Use?
Your favorite neutral-tasting oil for baking will work just fine. Instead of vegetable or sunflower oil, we typically use extra-light olive oil (not extra-virgin) or grapeseed oil. Non-GMO canola oil is also great for baking.
How Can I Make this Recipe Corn-Free?
You can use arrowroot starch or tapioca starch in place of the cornstarch in the vegan lemon curd.
Can I Use Other Citrus in this Cake?
Why not?! If Meyer lemons are in season, I would definitely splurge on those. But you could use this recipe formula to make a vegan lime cake, grapefruit cake, or even a sweet tangerine cake. But we recommend trying it as vegan lemon cake first!

- Pop the cooled cake back into the oven dish. Pour over the icing and use the back of a spoon or a spatula to spread it over the cake.
- Working quickly so that the icing doesn't set, rotate the dish 90 degrees. Use a spoon or the pastry bag to draw lines of lemon curd about ¾-1¼ inches apart. Use the long end of a spoon or a skewer to drag the curd left and right to create a marble effect.
- Allow the icing to set completely (about 1 hour ).
