I really wanted to make an Earl Grey crumble muffins recipe that tasted like actual Earl Grey. You know when you try something with a specific flavour and it’s just… missing? That was my mission here: a muffin with a really clear, fragrant bergamot kick, plus that yummy crisp streusel on top. I wanted a tender muffin that felt like something from your local bakery!
So, I didn’t just use brewed tea in these; I also snuck in finely ground Earl Grey leaves straight into the batter. That’s how you get that deep, aromatic tea flavour that goes all the way through each bite, along with those pretty little flecks. And the streusel on top is buttery and crumbles, adding a nice bit of texture to the soft muffin.
The trick to those tall, domed tops I was after is a quick blast of high heat at the start of baking. It really helps them rise up like little mountains, which is always so satisfying to see (you know those 10x speed baking videos? like that). I actually tested this a few times to get the tea flavour just right, and let’s just say my kitchen smelled incredible for days. Many muffins were consumed for research purposes.

The Perfect Earl Grey Crumble Muffins Recipe
Making these Earl Grey crumble muffins starts with the crumb topping, which you want to get chilling in the fridge right away. It’s just flour, brown sugar, cinnamon, and cold butter all mixed until it looks like little peas. This keeps it nice and crumbly when it bakes.
Next, you’ll get your Earl Grey tea ready for the muffin batter. You’ll need a strong brew that’s fully cooled down, plus some tea leaves finely ground up to go straight into the dry ingredients. That’s where a lot of the flavour comes from.
Then it’s all about creaming the butter and sugars until they’re light, then mixing in the eggs, sour cream, and vanilla. Don’t forget to add the cooled tea. Finally, you gently fold in the dry ingredients until just combined, overmixing can make muffins tough, and we don’t want that.
Fill your muffin cups almost to the top and pile on that chilled crumb topping. The initial hot oven blast helps them get those big, domed tops, then you lower the temperature to finish them off. It’s a simple little trick that makes a big difference.

Tips for Making Earl Grey Crumble Muffins
Finely grind the tea leaves – For the best flavour distribution and to avoid any gritty bits, I really recommend snipping open those tea bags and using a spice grinder. A mortar and pestle works too, just make sure they’re super fine.
Room temperature ingredients – This one’s a classic for a reason. Having your butter, eggs, and sour cream all at room temp helps everything mix together smoothly and creates a more even, tender crumb.
Don’t overmix the batter – As soon as you add the dry ingredients, mix just until no streaks of flour remain. Overmixing can develop the gluten too much, leading to tough muffins instead of light and airy ones.
Chill the crumb topping – Keeping your streusel cold before it goes into the oven helps it stay distinct and crisp. If it’s too warm, the butter can melt too quickly and the topping might just disappear into the muffin.

Earl Grey Muffin FAQs
Can I make these muffins ahead of time?
You sure can! These earl grey muffins keep well at room temperature in an airtight container for up to 3 days. If you want them to last longer, you can freeze them for up to 3 months.
What if I don’t have sour cream?
Plain full-fat yogurt works beautifully as a substitute for the sour cream. Just make sure it’s at room temperature before you mix it in so it incorporates smoothly into the batter.
Why did my crumb topping melt away?
This usually happens if your butter wasn’t cold enough when you mixed the streusel, or if the crumb topping got too warm before baking. Keeping the butter cold and chilling the mixed topping helps it maintain its structure and crispness in the oven.
Can I use decaf Earl Grey tea?
Absolutely, if you prefer! Using decaf Earl Grey tea won’t change the flavour or texture of the muffins at all. Just make sure it’s a good quality tea so you still get that lovely bergamot aroma.

Description
These tender, aromatic Earl Grey Crumble Muffins feature a heightened tea flavour and a crisp, buttery crumb topping. I developed this homemade Earl Grey streusel muffins recipe for a truly bold bergamot flavour and a moist crumb, all ready in under an hour.
Ingredients
Crumb Topping
- 1/4 cup (55g) brown sugar, packed
- 1/4 tsp cinnamon
- 1/4 cup (56g) unsalted butter, cold, diced
- 3/4 cup (95g) all-purpose flour
Muffins
- 2 cups (240g) all-purpose flour
- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp salt
- 2 tea bags (4g) Earl Grey tea leaves, finely ground
- 1/2 cup (113g) unsalted butter, softened to room temp
- 1/4 cup (55g) brown sugar, packed
- 1/3 cup (67g) granulated sugar
- 2 large eggs, room temp
- 1/2 cup (120g) sour cream, room temperature (or plain yogurt)
- 2 tsp vanilla extract
- 1/2 cup (120ml) strong brewed Earl Grey tea, cooled, 4-5 tea bags steeped for 5 minutes
Instructions
- Preheat your oven to 425°F (220°C). Line a 12-count muffin pan with paper liners; I like to sprinkle a few uncooked rice grains in each well before adding liners for easier release.
- Brew 4-5 Earl Grey teabags in 1/2 cup of boiling water, let them steep for 5 minutes, then remove the bags and allow the tea to cool completely.
- For the crumb topping, combine the brown sugar, cinnamon, and flour in a small bowl. Add the cold, diced butter and use your fingers or a fork to mix until pea-sized crumbles form. Place this in the fridge to keep it cold.
- In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and the finely ground Earl Grey tea leaves. Set this dry mixture aside.
- In a large bowl, beat the softened butter, brown sugar, and granulated sugar together with an electric mixer on medium-high speed for about 2 minutes until the mixture is light and creamy.
- Add the eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl, then mix in the sour cream and vanilla extract until just combined.
- Pour the cooled, strong brewed Earl Grey tea into the wet ingredients and mix briefly.
- Add half of the dry flour mixture to the wet ingredients and mix on low speed until just barely combined. Add the remaining dry mixture and mix until no dry streaks remain; be careful not to overmix.
- Divide the batter evenly among the 12 muffin cups, filling each one almost to the top.
- Retrieve the chilled crumb topping and sprinkle it generously over each muffin, about 1 tablespoon per muffin.
- Bake for 5 minutes at 425°F (220°C), then reduce the oven temperature to 375°F (190°C) and continue baking for another 15-20 minutes, or until a wooden skewer inserted into the centre comes out clean.
- Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
Notes
For the finest ground tea, I like to snip open the tea bags and use a spice grinder or a mortar and pestle. It helps distribute the flavour evenly and avoids any gritty texture.
These muffins keep well at room temperature in an airtight container for up to 3 days. If you want to store them longer, I recommend freezing them for up to 3 months; just thaw them in the fridge or at room temperature.
If you don’t have sour cream, plain full-fat yogurt works beautifully as a substitute. Just make sure it’s at room temperature for smooth incorporation into the batter.
