Ingredients
For the cake
1 cup/240 milliliters extra-virgin olive oil, plus more for greasing the pan
1 ½ cups/300 grams granulated sugar
2 tablespoons loose Earl Grey tea (from about 6 tea bags)
2 teaspoons baking powder
½ teaspoon baking soda
1 teaspoon kosher salt (such as Diamond Crystal)
2 cups/480 grams sour cream or whole-milk plain Greek yogurt
3 large eggs
2 teaspoons vanilla extract
3 cups/384 grams all-purpose flour
For the streusel
1 cup/128 grams all-purpose flour
1 cup packed/220 grams light or dark brown sugar
1 ½ teaspoons ground cardamom
½ teaspoon kosher salt (such as Diamond Crystal)
½ cup/115 grams unsalted butter, melted
Preparation
- Step 1
Heat oven to 350 degrees.
Prepare the pan for the cake:
- Step 2
Lightly grease a 9-by-13-inch metal or glass baking pan with olive oil and line with parchment paper, leaving an overhang on two sides.
Make the streusel:
- Step 3
In a medium bowl, combine the flour, brown sugar, cardamon and salt. Add the melted butter and stir with a fork until evenly moistened and various crumb sizes form. Refrigerate while you prepare the cake batter.
Prepare the cake:
- Step 4
In a large bowl, rub the granulated sugar and tea leaves together with your fingertips until the mixture is fragrant. Add the baking powder, baking soda and salt and whisk to combine. Add the sour cream, olive oil, eggs and vanilla, and whisk until very smooth.
- Step 5
Add the flour and stir gently until just combined (do not overmix, a few small lumps are fine).
- Step 6
Transfer the batter to the prepared baking pan and spread in an even layer. Crumble the streusel evenly over the top.
- Step 7
Bake until the streusel is browned and a toothpick inserted into the center of the cake comes out clean, 40 to 50 minutes.
- Step 8
Transfer the cake in the pan to a rack to cool for at least 45 minutes, then run a knife around the edges of the cake and transfer it to a cutting board using the parchment paper overhang. Cut into squares and serve. (You can also serve the cake directly from the pan.) The cake will keep, well wrapped or in an airtight container at room temperature, for up to 4 days. Alternatively, freeze the cake for up to 3 months.

I think your typical grocery store tea bag earl grey is not gonna cut it here. I used a really beautiful loose leaf earl grey, and ground it to a powder in a spice grinder. It was super earl grey-y and played well with the cardamom.
If the bergamot flavor of the Earl Grey fades in comparison with the cardamom, I'd opt for skipping it in the recipe altogether and serving it brewed and hot, alongside the cake.
Seems like everyone is saying you can't taste the Earl Gray. I tasted it because I accidentally put 2 tablespoons in the streusel as well. It was delicious! Totally fixes it. The cake is light. Don't think this is one that I will make all the time, but it is good and I am saving it to make again.
This is a banger! Made for a brunch, as 24 muffins baked at around 30 mins. Yuuuumm. Maybe I’ll serve with whipped cream, imagine that would be delish.
I would give it more than 5 STARS if I could. I used Harney and Sons Paris loose leaf tea and I loved the flavor. I used a Japanese mortar and pestle to mix the tea with the 1/2 cup sugar. After I crushed it, I transferred it to a bowl with the remaining cup sugar and used my fingers continue to mix the tea with the sugar. The topping was firm when I used it but I think that helped make a more defined streusel. I will make it again. It had a wonderful flavor.
Made with quality decaf chai - mortar and pestled the blend - definitely would recommend! Tastes like childhood nostalgia coffeecake
