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.
Private Notes

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.
I used a high quality very fragrant loose leaf earl grey from a specialty tea shop and the flavor absolutely shines in this cake. In fact, I doubled the cardamom and the earl grey was still prominent. Quality loose leaf is the key to this recipe. Super moist and delicious. There were even some distinct floral notes in the tea that came through. Next time I will add some orange zest to the sugar. I halved the recipe and made it in a standard round cake pan. Also added pecans to the crumb.
I just made this for Mother's Day brunch and it was so delicious and everyone loved it. Followed recipe exactly as written. Used Tazo organic earl grey. Tea flavor was subtle but wonderful. Didn't find olive oil flavor to be overpowering at all. So so good.
Similar to some, I used my spice grinder to pulse about five cardamom pods and some extra earl grey for the streusel. I upped the earl grey in the batter. Would make again for sure - moist, easy, and a crowd pleaser.
