- Unsalted butter (softened): Brings richness and helps create that signature tender crumb.

How to Make Vegetarian
Step 1: Prep the Pan and Oven
Start by heating your oven to 350°F (175°C) and prepare your baking pan—a simple but crucial step! Grease and line an 8-inch square pan so your Vegetarian cake releases effortlessly, setting you up for those perfect, tidy slices.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This quick whisk ensures your leaveners are evenly distributed, giving you that uniform tall lift and texture every good Vegetarian cake deserves.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar together until the mixture is fluffy and pale. This step is where magic begins—the more air you incorporate, the lighter and softer your cake will be.
Step 4: Add Eggs and Vanilla
Crack in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract next, letting its rich aroma infuse your batter. The eggs keep everything moist and cohesive, while the vanilla brings unmistakable warmth and classic Vegetarian flavor.
Step 5: Combine Wet and Dry Ingredients
Now, gently fold in the dry ingredients, alternating with the buttermilk. Start and end with the dry mix for the fluffiest result, and mix until just combined—no overbeating! The buttermilk’s acidity keeps everything exceptionally tender, a must in any good Vegetarian bake.
Step 6: Fold in the Blueberries
Gently stir in the fresh blueberries, being careful not to over-mix. This prevents them from breaking and coloring your batter, giving you the most beautiful pops of berry in every bite of your Vegetarian cake.
Step 7: Bake
Pour the batter into your prepared pan and smooth the top. Slide it into the preheated oven and bake for 35–40 minutes. You’ll know it’s ready when a toothpick inserted in the center comes out clean. Let it cool completely in the pan—this keeps the crumb intact and prevents breakage.
Step 8: Make the Glaze
While the cake cools, warm the blueberry jam and lemon juice in a small saucepan until just runny and easily spreadable. This becomes your glossy, fruity topping that truly takes this Vegetarian dessert over the top.
Step 9: Finish, Decorate and Serve
Once your cake is cool, pour the warm glaze over the top, spreading it gently. Scatter extra fresh blueberries and a handful of mint leaves if you like color and a herbal touch. Slice generously and dig in—your Vegetarian masterpiece is ready!
How to Serve Vegetarian
Garnishes
This cake loves a little flourish! Dot the top with extra fresh blueberries just before serving, and tuck in a few sprigs of mint for brightness. Want to go extra special? A light dusting of powdered sugar or a dollop of whipped cream makes your Vegetarian creation look absolutely irresistible.
Side Dishes
While this cake is a showstopper solo, it also shines with thoughtful pairings. A scoop of vanilla ice cream on a warm day, or a spoonful of tangy Greek yogurt for brunch, both play beautifully with the sweet, tart flavors. Pair with strong coffee or an herbal tea for a full Vegetarian dessert experience.
Creative Ways to Present
Try cutting the cake into bite-sized squares and serving them as a dessert platter at your next picnic or brunch gathering. Alternatively, layer slices with extra jam and whipped cream in small glasses for a Vegetarian berry trifle. Even simple squares wrapped in parchment and tied with twine make delightful homemade gifts.
Make Ahead and Storage
Storing Leftovers
This cake keeps surprisingly well! Cover any leftovers tightly and store in an airtight container at room temperature for up to two days. For longer storage, pop it in the fridge; just let it come back to room temp for the softest bite. The glaze helps lock in that classic Vegetarian moisture.
Freezing
If you want to enjoy your Vegetarian cake later, you’re in luck. Freeze individual, unglazed slices wrapped tightly in plastic and foil for up to two months. When ready to eat, thaw overnight in the fridge and then glaze just before serving for that bakery-fresh finish.
Reheating
To bring chilled or thawed slices back to maximum tenderness, set them out at room temperature for about 30 minutes. For a warm treat, a quick zap in the microwave (10–15 seconds) revives the crumb. Add glaze and toppings after reheating for the freshest Vegetarian cake flavor.
FAQs
Can I use frozen blueberries?
Absolutely! If using frozen blueberries, toss them in a teaspoon of flour to help prevent them from sinking in the batter. Add them straight from the freezer—don’t thaw first—to keep your Vegetarian cake perfectly moist and avoid blue streaks.
Can I make this cake gluten-free?
Yes! Swap the all-purpose flour for your favorite 1-to-1 gluten-free flour blend. The texture will be just as soft and lovely, so everyone can enjoy a slice of this Vegetarian cake.
What if I don’t have buttermilk?
No problem—just add 1 tablespoon of lemon juice or vinegar to 1 cup of milk, let it sit for 5 minutes, and use it as a homemade buttermilk substitute for your Vegetarian baking.
How do I know when the cake is fully baked?
The best way is the toothpick test: insert one into the center and it should come out clean or with a few moist crumbs. The edges will look golden and slightly pulled from the pan, which is exactly how this Vegetarian classic should look.
Can I double the recipe for a crowd?
Certainly! To serve a larger group, simply double the ingredients and use a 9×13-inch pan. The baking time may increase slightly, so keep an eye out and test with a toothpick for doneness. Sharing this Vegetarian cake with friends makes any gathering even sweeter.
