Ingredients
FOR THE CRUMB TOPPING
255 grams all-purpose flour (about 1 ½ cups)
75 grams granulated sugar (about ⅓ cup)
105 grams dark brown sugar, lightly packed (about ½ cup)
6 grams ground cinnamon (about 1 ½ teaspoons)
1 gram ground allspice (about ¼ teaspoon)
1 gram fine sea salt (about ¼ teaspoon)
170 grams unsalted butter, melted (12 tablespoons; 1 ½ sticks)
FOR THE CAKE
170 grams unsalted butter, at room temperature (12 tablespoons; 1 ½ sticks)
200 grams granulated sugar (about 1 cup)
3 large eggs, at room temperature
1 cup sour cream
1 ½ teaspoons vanilla extract
Finely grated zest of 1 lemon
325 grams all-purpose flour (about 2 ½ cups)
10 grams baking powder (about 2 teaspoons)
3 grams baking soda (about ½ teaspoon)
3 grams fine sea salt (about ½ teaspoon)
½ pint fresh blackberries (or use raspberries, blueberries or diced strawberries)
Preparation
- Step 1
Heat oven to 350. Grease or line 24 muffin cups.
- Step 2
Make the crumb topping: whisk together flour, sugars, spices and salt in a medium-sized bowl. Pour in melted butter and stir until crumbs form.
- Step 3
Prepare the cake: using an electric mixer fitted with the paddle, cream butter and sugar until light and fluffy, about 5 minutes. Add eggs 1 at a time, then scrape down sides of mixer. Mix in sour cream, vanilla and zest.
- Step 4
In a separate bowl, mix together flour, baking powder, baking soda and salt. With mixer on low speed, add flour mixture to batter and beat until just mixed. Fold in berries with a spatula and make sure batter is completely mixed.
- Step 5
Spoon batter into prepared muffin pans, filling each cup only halfway. Pinch large crumbs from topping mixture and scatter evenly on top of the batter.
- Step 6
Bake for 25 to 30 minutes, until muffins are golden and their centers spring back when very gently pressed with a finger. (A cake tester will come out with crumbs attached, but it shouldn’t be wet.) Transfer muffins to a wire rack. Serve warm or let cool completely and freeze.

Wonderful as muffins, but hard to get the crumb thick enough. Only modification I made to the ingredients was to double the cinnamon. Second time I made it decided sure why not crumb cake. Spread 2/3 of the batter in a 9x12 pan, covered it in local wild blackberries. Dotted on the rest of the batter and covered the whole thin with the full amount of crumb. Had to about double the baking time. Turned out moist and incredible
Delicious and the streusel topping is the key factor! Instead of melting the butter, use one stick of softened butter instead, a bit less gran sugar and flour, 1/4 cup of uncooked oats, & a bit of finely chopped pecans. To make the topping: roll dough to make small clusters and place on top of each muffin before baking. Use all leftover bits - you can’t have too much streusel! Before putting into the oven, add a few more sprinkles of turbinado sugar. And, you must double the berries!!!
These muffins are amazing! They freeze and reheat wonderfully!I had way too much crumb mixture left over. On my second go I made half as much crumb mixture and still had some left over.
I didn’t have any dark brown sugar so I added molasses and espresso powder to my light brown sugar it and worked really well, very nutty! Also, only make half as much crumbs, maybe even a third, there was so much of it leftover.
Agree with many others that the streusel topping was about double what was needed. To cut down on total butter intake I subbed in canola oil instead of butter in the batter so to get the aeration back in since I omitted the butter creaming, I whipped the eggs with the sugar until it was pale and then beat in the rest of the ingredients before folding in the dry ingredients. I had to nearly double the baking time but it turned out moist and delicious. Didn’t miss the butter flavor at all (since the topping still had butter). Keep in mind butter is 80% fat and 20% water so subbing in oil means you need a little less volume wise and might need a tbsp or two of water.
Skipped the topping - sprinkled turbinado sugar on top. Used frozen berries, thawed, drained, and tossed with 1 T flour. Made 12 Jumbo muffins - done in 25 minutes. Lovely, fluffy muffins.
