It was the kind of moment where you just smile and let out a sigh because, you know, you’ve stumbled onto something truly special.

Years ago, when I was knee-high to a grasshopper, my grandma would brew Earl Grey on rainy days, and we’d sit by the window with a plate of lemon shortbread.

I wish I’d found this combo sooner—it’s pure, nostalgic comfort with a fresh twist.

What Ingredients You Will Need

This Earl Grey Lavender Sheet Cake recipe uses simple, wholesome ingredients to deliver bold flavor and a tender crumb—no fuss, just magic. Most of these are pantry staples, and you can easily swap things if needed. Here’s what you’ll need:

• For the Cake:
  • 2 cups (240g) all-purpose flour (use gluten-free flour blend if needed)
  • 1½ cups (300g) granulated sugar
  • 1 tbsp Earl Grey tea leaves (about 2 tea bags, finely ground)
  • 1½ tsp dried culinary lavender (not too much—just a hint!)
  • 2½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup (240ml) whole milk (substitute almond or oat milk for dairy-free)
  • ½ cup (120ml) sour cream (or plain Greek yogurt for extra tang)
  • ¾ cup (170g) unsalted butter, melted and cooled (use dairy-free butter if preferred)
  • 3 large eggs, room temperature
  • 2 tsp vanilla extract
  • Zest of 1 lemon (adds brightness)
• For the Lemon Cream Cheese Frosting:
  • 8 oz (225g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 2½ cups (300g) powdered sugar, sifted
  • Zest of 1 lemon
  • 2 tbsp lemon juice (freshly squeezed for best flavor)
  • 1 tsp vanilla extract
  • Pinch of salt
• Optional Garnishes:
  • Extra dried lavender (for sprinkling)
  • Thin lemon slices or zest curls

If you’re feeling adventurous, swap the milk for coconut milk for a subtle tropical note, or try Meyer lemon instead of regular for a sweeter finish. I love using Twinings Earl Grey and McCormick dried lavender—never let me down! For gluten-free folks, a 1:1 flour blend works beautifully. If you want it lactose-free, coconut yogurt and vegan butter are easy subs. In summer, fresh lavender blooms add a lovely touch, but dried works year-round.

Keep it simple, mix it up—this ingredient list is friendly to changes and substitutions, so you can make it work for you.

Equipment Needed

Baking this sheet cake is pretty straightforward, but having the right tools makes all the difference. Here’s what I reach for every time:

• 13×9-inch baking pan (metal or glass both work, but I prefer metal for even browning)
• Large mixing bowls (at least two—one for dry, one for wet ingredients)
• Whisk and rubber spatula (for smooth mixing and scraping every last bit!)
• Electric mixer or stand mixer (hand mixer works if that’s all you’ve got)
• Measuring cups and spoons (accuracy is key)
• Microplane or fine grater (for lemon zest)
• Fine mesh sieve or sifter (for powdered sugar)
• Parchment paper (for easy cake removal, but not essential)

If you don’t have a stand mixer, don’t sweat it—a whisk and some elbow grease will get you there. Glass pans are fine, but you might need to bake a few minutes longer. I’ve used silicone pans in a pinch, though I find the texture is best in metal. For budget-friendly options, look for generic brands at your local store—they’re just as good if you treat them right. Remember, keep your mixer clean and check for loose wires (learned that the hard way!).

Preparation Method

Ready to bake? Here’s how to make this Earl Grey Lavender Sheet Cake with Lemon Frosting, step by step. I’ll include my best tips and what to watch for so you get perfect results every time.

1. Preheat & Prep: Preheat your oven to 350°F (175°C). Line a 13×9-inch pan with parchment paper or lightly grease it. This helps with easy removal later.
2. Steep the Milk: Warm the milk gently in a saucepan (don’t boil—just simmer). Add Earl Grey tea leaves and dried lavender. Steep for 5-7 minutes, then strain out the solids. Let the milk cool to room temperature. (The milk will be fragrant and slightly tinted—don’t worry, that’s perfect!)
3. Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Add lemon zest for brightness.
4. Combine Wet Ingredients: In another bowl, whisk melted butter, eggs, sour cream, vanilla extract, and the cooled, steeped milk. Mix until smooth—don’t overbeat.
5. Make the Batter: Pour wet ingredients into the dry. Mix gently with a spatula until just combined. Batter should be thick but pourable—if too stiff, add a splash of milk.
6. Bake: Pour batter into prepared pan and smooth the top. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean. The cake will be lightly golden and springy to the touch.
7. Cool: Let cake cool in the pan for 10 minutes, then lift it out (if using parchment) and cool completely on a wire rack. Resist the urge to frost while warm—otherwise, the frosting will melt and slide off!
8. Make the Frosting: Beat softened cream cheese and butter together until creamy—about 2 minutes. Add powdered sugar, lemon zest, lemon juice, vanilla, and a pinch of salt. Beat until light and fluffy, 2-3 minutes. Taste and adjust lemon juice if needed.
9. Frost: Spread the frosting evenly over the cooled cake. Use a spatula or the back of a spoon for swoopy swirls. Sprinkle extra dried lavender or lemon zest curls for a Pinterest-perfect finish.
10. Slice & Serve: Cut into squares and serve! The cake is best at room temperature, and the flavors develop even more after a few hours.

Notes & Troubleshooting: If your cake sinks, the milk may have been too hot, or the batter was overmixed. If the frosting seems runny, chill it for 10 minutes before spreading. Don’t skip steeping the milk—it’s what gives the cake that dreamy Earl Grey aroma. I like to prep the frosting while the cake cools to save time. Clean as you go—makes it way easier!

Cooking Tips & Techniques

After baking this sheet cake more times than I can count, I’ve picked up a few tricks that make a world of difference. Here’s what works, what doesn’t, and how to get the best results:

• Tea Steeping: Don’t boil the milk—just a gentle simmer. Overheating makes the tea bitter and the lavender too strong. Learned this the hard way!
• Mixing: Gently fold the wet and dry ingredients together—overmixing leads to dense cake. If there are a few streaks of flour, that’s okay.
• Butter Temperature: Melted but cooled butter is key. If it’s too hot, it’ll scramble the eggs.
• Frosting Fluffiness: Beat the cream cheese and butter longer than you think—2-3 minutes. It gets lighter and easier to spread.
• Timing: Make the frosting while the cake cools. If you’re short on time, chill the cake in the fridge for 20 minutes before frosting.
• Common Mistakes: Using too much lavender can make the cake taste soapy. Stick to the recipe’s amount for just the right floral note.
• Personal Failures: I once tried doubling the lavender—big mistake! Keep it subtle and balanced.
• Multitasking: Prep your garnishes while the cake bakes. Lemon zest curls and lavender sprinkles look beautiful and are quick to make.
• Consistency: Always measure ingredients accurately. Weighing flour and sugar is more reliable than scooping—trust me!

If you’re baking for a crowd, you can make the cake a day ahead. The flavors actually get better overnight. For even slices, chill the frosted cake for 30 minutes before cutting—makes it less messy and more Instagram-worthy.

Variations & Adaptations

Want to switch things up? This Earl Grey Lavender Sheet Cake is super flexible—here are some delicious ways to make it your own:

• Gluten-Free: Use a 1:1 gluten-free flour blend (like Bob’s Red Mill). The texture stays fluffy and moist—no weird aftertaste.
• Vegan Option: Substitute dairy-free butter, coconut yogurt for sour cream, and plant-based milk. For eggs, use 3 tbsp flaxseed meal mixed with 9 tbsp water (let it gel for 10 minutes).
• Seasonal Twist: In summer, swap dried lavender for fresh blossoms (just remember, a little goes a long way). In winter, add a hint of orange zest to the batter.
• Flavor Boost: Add ½ cup blueberries to the batter for a juicy pop, or a tablespoon of honey for extra sweetness.
• Cooking Methods: Bake as cupcakes for single servings—reduce bake time to 20-22 minutes. Or, make a layer cake by doubling the recipe and splitting between two round pans.
• Allergen Substitutions: Use lactose-free cream cheese and butter for those avoiding dairy, or skip the nuts entirely if you’re decorating.

My personal favorite adaptation? Adding a thin layer of lemon curd under the frosting—extra zing, extra smiles. Honestly, don’t be afraid to experiment. This cake is forgiving, and the flavor combos are endless!

Serving & Storage Suggestions

This Earl Grey Lavender Sheet Cake shines at room temperature, letting all those lovely flavors come through. Slice it into neat squares for a pretty presentation—perfect for parties, brunch, or even afternoon tea.

Serve with a cup of Earl Grey (of course) or a cold glass of lemonade. It pairs well with fresh berries, whipped cream, or even a scoop of vanilla ice cream if you’re feeling decadent.

For storage, keep the cake covered in the refrigerator for up to 4 days. The lemon frosting keeps everything moist, and the flavor actually improves after a day. For longer storage, wrap slices individually and freeze for up to a month—thaw in the fridge overnight and bring to room temp before serving.

To reheat, pop a slice in the microwave for about 10 seconds (just enough to soften, not melt the frosting). If you’re taking it to a picnic or potluck, transport in a lidded container and sprinkle fresh lavender on top right before serving for max visual appeal. (Trust me, everyone will ask for the recipe!)

From my perspective, this cake is a treat that brings a little joy to any day. The ingredients are wholesome and straightforward, and with a few tweaks, it fits most dietary needs. Balance and moderation, that’s always my motto when it comes to sweets!

FAQs

Can I use Earl Grey tea bags instead of loose leaf?

Absolutely! Just snip open two tea bags and use the leaves. Make sure to grind them a bit if they’re chunky.

Use only the specified amount of lavender—too much can be overpowering. Stick to culinary-grade lavender and measure carefully.

Can I make this cake ahead of time?

Yes! Bake the cake a day ahead and store it covered in the fridge. Frost before serving for best texture and flavor.

What’s the best way to freeze leftovers?

Wrap individual slices tightly in plastic wrap, then place in a freezer bag. Thaw in the fridge overnight and bring to room temperature before eating.

Can I use a different frosting?

Definitely! Vanilla buttercream or whipped cream work well, but lemon cream cheese frosting is my favorite for this flavor combo.
