Irresistible Upside Down Rhubarb Muffins


  • Total Time: 40 minutes
  • Yield: 12 muffins

Description

These muffins feature a tender, moist crumb crowned with a sticky, sweet-tart caramelized rhubarb topping. They are a perfect celebration of spring’s bounty and an unforgettable treat.


Ingredients

  • 1 ½ cups (180g) all-purpose flour
  • ½ cup (100g) packed light brown sugar, divided
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 cup (240ml) buttermilk, at room temperature
  • ⅓ cup (80ml) unsalted butter, melted and slightly cooled
  • 1 large egg, at room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups (about 200g) fresh rhubarb, trimmed and chopped into ½-inch pieces
  • Optional: ¼ teaspoon ground cinnamon or ginger for the topping

Instructions

  • Preheat Oven & Prep Muffin Tin: Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin generously or line with paper liners and spray the inside of the liners.
  • Prepare Rhubarb Topping: In a small bowl, combine the chopped rhubarb with 2 tablespoons of the brown sugar and optional cinnamon/ginger. Divide this mixture evenly among the prepared muffin cups, pressing gently into the bottom.
  • Combine Dry Ingredients: In a large bowl, whisk together the flour, remaining brown sugar, baking powder, baking soda, and salt until well combined.
  • Combine Wet Ingredients: In a separate medium bowl, whisk together the buttermilk, melted butter, egg, and vanilla extract until smooth.
  • Mix Batter: Pour the wet ingredients into the dry ingredients. Using a spatula, gently fold until just combined. Do not overmix; a few lumps are fine.
  • Fill & Bake: Divide the batter evenly over the rhubarb in each muffin cup, filling about two-thirds full. Bake for 18-22 minutes, or until golden brown and a wooden skewer inserted into the center comes out clean.
  • Cool & Serve: Let the muffins cool in the tin for 5 minutes before inverting them onto a wire rack to cool completely. Enjoy warm or at room temperature!
