Pumpkin Pecan Cupcakes with Rum and Brown Sugar Swiss Meringue Buttercream

Phew!  That is a mouthful!  But worth every last syllable I guarantee you.

This is actually a recipe for a bundt cake that I found a few years ago.  And I have made it as a bundt cake with some Rum Syrup brushed on top many times and it is fantastic!  Today we are going to a BBQ so I opted to make these as cupcakes and add my favourite Swiss Meringue Buttercream, using the Rum Syrup as flavouring.

I love fall baking.  I know that it’s still technically summer, but markets are starting to display beautiful little pie pumpkins just shouting my name.  Who doesn’t love a good pumpkin dessert (my mom makes the best pumpkin pie hands down).  I roasted a few pumpkins the other day to use for this recipe and froze the rest for later use.

Pumpkin Pecan Cupcakes

  • 3/4 chopped pecans
  •  1-2/3 cups packed brown sugar
  •  1/4 cup softened butter
  •  3 eggs , room temperature
  • 3/4 cup vegetable oil
  •  2 cups roasted pumpkin purée
  •  2-1/2 cups all-purpose flour
  •  2 tsp baking powder
  •  1-3/4 tsp ground cinnamon
  •  1 tsp baking soda
  •  1 tsp ground ginger
  •  3/4 tsp salt
  •  1/4 tsp ground nutmeg
  •  1/4 tsp ground allspice



  • 1/4 cup butter
  • 2/3 cup brown sugar
  • 1/4 cup dark rum

Line 2 muffin tins with liners or grease and flour a  10″ bundt pan.

1.  On baking sheet, toast pecans in 350°F (180°C) oven until fragrant, about 8 minutes; let cool.

2.  In small bowl, stir pecans with 2 tbsp of the brown sugar and sprinkle over the bottom of each cupcake liner (about 1/2 tsp).  Or, if using a bundt pan sprinkle around the bottom of greased and floured 10″ pan.

3.  In large bowl, beat remaining sugar with butter and beat in eggs, 1 at a time. Beat in oil until fluffy. Beat in pumpkin until

4.  In separate bowl, whisk together flour, baking powder, cinnamon, baking soda, ginger, salt, nutmeg and allspice; stir into egg mixture, just until mixed.   Fill liners or pan.

5.  Bake in 350°F oven until cake tester inserted in centre comes out clean, about 24 minutes for cupcakes and 50 minutes for bundt cake.   I removed cupcakes immediately to a rack to cool.  Let bundt cool on rack for 10 minutes then remove from pan and transfer to rack.

Syrup: In small saucepan, melt butter over medium heat.   Stir in sugar and 3 tbsp water.  Boil until dissolved and thickened,
about 3 minutes. Stir in rum and boil for 1 minute. Brush over cakes.  * I brushed some syrup on top of the cupcakes as they were cooling and used the rest in my buttercream.

Rum and Brown Sugar Swiss Meringue Buttercream

5 large egg whites

pinch of salt

1 1/4 cups brown sugar

4 sticks unsalted butter, very soft

1 tsp vanilla extract

1/2 cup rum syrup (above)

1.  Fill a saucepan (large enough to fit your mixing bowl just a few inches) with a few inches of water.  Bring the water to a boil, then reduce heat to med-low so water continues to simmer.

2.  In your stand mixer bowl, hand whisk the egg whites, sugar and salt just until combined.  Place over simmering pot and whisk for approx 4 mins until the egg whites are hot (about 150 degrees).  The sugar should be dissolved by this time as well.  Place bowl on stand mixer and attach the whisk attachment.  Whisk on medium until whites have increased in volume and the outside of the bowl is just slightly warm to the touch.

3.  Remove whisk attachment and replace with paddle attachment.  Beat on low-speed until mixture is completely cooled.  Increase speed to medium and add butter pieces one at a time.  Scrape the bowl and continue to beat until buttercream is glossy, smooth and thick.  It may separate at first, but continue beating and it will emulsify.  Add vanilla flavouring and rum syrup (to taste) and beat until combined.  Use immediately.

Garnish with toasted pecans.

    Can the rum syrup be replaced with something else?

    Does the brown sugar SMBC travel well? We’ll traveling about 3 hours away and I just want to make sure as I’ve never made Swiss Buttercream before. Thanks!! 🙂

    Just saw this through a friend who calls me the cupcake queen along with my church. About the recipe for the frosting…do the cupcakes need to be kept in the fridge or can they be left out?
