How to Make Earl Grey Lavender Sheet Cake with Lemon Frosting

Preheat and prepare pan — Preheat oven to 350°F (175°C). Line a 13×9-inch pan with parchment or lightly grease it. This helps the cake lift out cleanly.
Steep the tea — Warm the milk gently in a small saucepan until steaming but not boiling. Remove from heat, add the ground Earl Grey and dried lavender, and let steep 5–7 minutes. Steeping releases the bergamot and floral notes.
Strain and cool — Strain the milk through a fine mesh into a bowl, pressing gently on solids. Discard solids. Let the milk cool to room temperature so it won’t cook the eggs.
Mix dry ingredients — In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, and lemon zest. Mixing lemon zest with dry ingredients spreads the citrus oil evenly.
Combine wet ingredients — In another bowl, whisk melted butter, eggs, sour cream, vanilla, and the cooled, steeped milk until smooth and even.
Fold batter — Pour the wet mix into the dry mix. Use a spatula to fold gently until just combined. Do not overmix; batter should be thick but pourable. Add a splash of milk if it seems too thick. Overmixing makes the cake dense.
Bake — Pour the batter into the prepared pan and smooth the top. Bake 28–32 minutes, or until a toothpick in the center comes out clean. The top should be light golden.
Cool — Let the cake cool in the pan 10 minutes, then lift out using parchment and finish cooling on a wire rack. Cooling fully prevents the frosting from melting.
Make frosting — Beat softened cream cheese and softened butter until creamy (about 2 minutes). Add powdered sugar, lemon zest, lemon juice, vanilla, and a pinch of salt. Beat 2–3 minutes until light and fluffy. Taste and adjust lemon or sugar as needed.
Frost and garnish — Spread frosting over the cooled cake. Sprinkle a few dried lavender buds and add thin lemon slices or zest curls if you like. Slice into squares and serve at room temperature.

How to serve Earl Grey Lavender Sheet Cake with Lemon Frosting

Cut into even squares and serve on a small plate with a hot cup of tea or coffee.
For a tea party, place thin lemon slices and a small sprig of lavender on each piece.
Serve at room temp so the frosting is soft and the flavors are balanced. Cold frosting can mute the lemon.

How to store Earl Grey Lavender Sheet Cake with Lemon Frosting

Room temperature: Store covered for up to 24 hours in a cool spot.
Refrigerator: Keep in an airtight container for 3–4 days. Bring to room temperature before serving for best texture.
Freezing: Freeze unfrosted cake layers wrapped well for up to 2 months. Thaw in the fridge, then frost before serving. You can also freeze frosted slices for up to 1 month; thaw slowly in fridge.

Tips to make Earl Grey Lavender Sheet Cake with Lemon Frosting

Grind the tea leaves small so they steep fully and blend into the milk.
Don’t boil the milk — heating too hot will make bitter tea.
Cool the steeped milk before adding to eggs to avoid scrambling.
Use room-temperature eggs for a smoother batter and better rise.
Avoid overmixing after adding flour; fold until just combined.
If you want a milder lavender, reduce to 1 tsp dried lavender.

Variation

Gluten-free: Swap a 1:1 gluten-free flour blend for the all-purpose flour.
Dairy-free: Use plant milk, dairy-free butter, and a dairy-free cream cheese for the frosting.
Lemon glaze: Replace cream cheese frosting with a simple lemon glaze (powdered sugar + lemon juice) for a lighter finish.
Less sweet: Cut powdered sugar in the frosting by ¼ cup and add more lemon juice to taste.

FAQs

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

Yes. Remove the tea from about 2 tea bags and grind finely or open the bags and use the contents. Steep the same way for 5–7 minutes.

How do I make this cake gluten-free?

Use a reliable 1:1 gluten-free flour blend that already includes xanthan gum. The texture will be similar. Bake times remain the same; check with a toothpick.

Can I skip the lavender?

Yes. If you don’t like lavender, omit it and steep only the Earl Grey. The cake will still have a lovely bergamot tea flavor.

Is this cake freezer-friendly?

Yes. Unfrosted cake freezes best for up to 2 months. Wrap well and thaw in the fridge before frosting. Frosted pieces can freeze up to 1 month.

Why did my frosting turn runny?

If the cream cheese or butter was too warm, the frosting can be soft. Chill the frosting briefly and beat again, or add a little more powdered sugar to firm it.
