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) and grease a muffin tin.
- In a small saucepan, melt 1/4 cup butter over low heat. Stir in 3/4 cup brown sugar until combined. Pour this mixture into the bottom of the muffin tin to create a sticky base.
- Place the rhubarb pieces evenly over the brown sugar mixture in the muffin tin.
- In a large bowl, whisk together the melted butter, sugar, and egg until smooth.
- In another bowl, mix the flour, baking powder, salt, and nutmeg.
- Gradually add the dry ingredients to the wet ingredients, alternating with milk and vanilla, until everything is just combined. Be careful not to overmix.
- Spoon the batter over the rhubarb in the muffin tin, filling each cup about three-quarters full.
- Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
- Let the muffins cool for a few minutes, then carefully invert the muffin tin onto a plate to release the muffins. Enjoy warm or at room temperature.

how to serve Irresistible Upside Down Rhubarb Muffins

how to store Irresistible Upside Down Rhubarb Muffins
If you have leftover muffins, store them in an airtight container at room temperature for up to three days. For longer storage, you can freeze them. Wrap each muffin tightly in plastic wrap, then place them in a freezer bag. They can be stored in the freezer for up to three months.
