How to Make Irresistible Upside Down Rhubarb Muffins
Ingredients:
- 1.25 cups rhubarb (sliced into 1/2-inch thick pieces)
- 1/4 cup butter (I like Kerrygold unsalted butter for this)
- 3/4 cup brown sugar
- 1/3 cup butter (melted and cooled to room temperature)
- 1/3 cup sugar
- 1 egg
- 1.75 cups flour (I always use King Arthur all-purpose flour)
- 2 tsp baking powder
- 1/2 tsp salt
- 1/2 tsp nutmeg (freshly grated for best aroma)
- 1/2 cup milk
- 1/2 tsp vanilla extract
Directions:
- Preheat your oven to 350°F (175°C). Grease a muffin tin with non-stick spray or line it with muffin liners.
- In a small saucepan, melt 1/4 cup of butter over medium heat. Add 3/4 cup brown sugar and stir until combined. Pour this mixture into the bottom of the prepared muffin tin.
- Next, distribute the sliced rhubarb evenly over the brown sugar mixture in the muffin tin.
- In a mixing bowl, combine the remaining 1/3 cup melted butter, 1/3 cup sugar, and the egg. Mix well.
- In another bowl, whisk together the flour, baking powder, salt, and nutmeg.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Don’t overmix!
- Slowly stir in the milk and vanilla extract until the batter is smooth.
- Spoon the batter into each muffin cup, filling them about 3/4 full.
- Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the muffins to cool for a few minutes in the tin, then carefully invert them onto a wire rack to cool completely.
How to Serve Irresistible Upside Down Rhubarb Muffins
Serve these muffins warm or at room temperature. They are delicious on their own, but you can also enjoy them with a dollop of whipped cream or a sprinkle of powdered sugar for extra flair. Pair them with a cup of tea or coffee for a delicious breakfast or snack.


How to Store Irresistible Upside Down Rhubarb Muffins
Store any leftover muffins in an airtight container at room temperature for up to 2 days. For longer storage, you can freeze them. Wrap each muffin tightly in plastic wrap, then place them in a freezer-safe bag. They will last for about 3 months in the freezer.



Tips to Make Irresistible Upside Down Rhubarb Muffins

Variation
You can try this recipe with other fruits like strawberries or blueberries for a different flavor profile. Just replace the rhubarb with an equal amount of your chosen fruit.
