Blackberry Rhubarb Crumble Muffins
Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners.
- In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly combined.
- Cut cold butter into small cubes and add to the flour mixture. Use a pastry cutter or fork to incorporate the butter until the mixture resembles coarse crumbs.
- In a separate bowl, whisk together the eggs, buttermilk, and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients and gently fold with a spatula until just combined; do not overmix.
- Gently fold in the blackberries and chopped rhubarb, distributing them evenly throughout the batter.
- Spoon the batter into the prepared muffin liners, filling each about 3/4 full to leave space for rising.
- In a small bowl, combine additional flour, sugar, and cold butter to make the crumble topping. Use your fingers or a fork to mix until crumbly.
- Sprinkle the crumble evenly over each muffin, pressing down lightly to help it adhere.
- Bake the muffins for about 22-25 minutes, or until they are golden brown and a toothpick inserted in the center comes out clean.
- Remove from oven and let the muffins cool in the pan for 5 minutes before transferring to a wire rack to cool completely. Enjoy the warm, fragrant aroma and juicy bites.
Once out of the oven, the muffins cool just enough for the crumble topping to remain crisp. The aroma lingers, inviting another bite and another memory. These Blackberry Rhubarb Crumble Muffins are proof that the simplest ingredients can create a moment of joy worth savoring.
They’re perfect for sharing or keeping on hand for those busy mornings. A small reminder that baking can be both a nostalgic act and a celebration of what’s currently in season—bright, bold, and beautifully fleeting.
