#85) Rhubarb Pie Cupcakes

I may love sweet treats, but I have to tell ya, I really do love tart flavours.  Give me a bit of lemon any day!  So that's why I was so excited when one of husband's co-workers kindly gave me a big bag of fresh rhubarb from her garden.  The only question was, "What do I make?"

I could have done the ol' strawberry rhubarb combination, but that just seemed too straight forward.  Then it dawned on me that I haven't made cupcake in way too long!  So there you have it - a rhubarb pie cupcake :)

The cupcake itself is kind of heavy, due the skipped creaming step, but I wanted to mimic a tart shell you might put your pie filling in.  The pie filling is straight up rhubarb with just enough sweetness to take the edge off.  And the frosting?  OMG the frosting!  I am not great at frosting and I am not a huge fan of how overly sweet homemade frosting can be.  Also, I wanted to re-create the whipped cream you might have on a piece of rhubarb pie.  So I went on the hunt for something a little different and found 7-minute frosting.  Okay, mine took more like 14 minutes, but SO worth it!  It's like a fluffy marshmallow sitting on the top of the cupcakes.

Give 'em a try and let me know what you think :)  Oh, and don't forget to vote for our blogiversay recipe revisit to your left.  Thanks!

Rhubarb Pie Filling

Ingredients

4 cups chopped rhubarb

1 1/3 cups sugar (start with 1 cup and add accordingly throughout cooking process depending on the tartness of your rhubarb)

6 tablespoons flour

Steps

-Combine all ingredients in large saucepan.  Cook over med-high heat for about 10 minutes, until liquid from rhubarb moistens the mixture.  (I covered mine and stirred often.)
-Reduce heat to low and let cook until all the rhubarb pieces have broken down.  Mixture should be thick.

-Remove from saucepan to bowl and allow to cool completely.

Cupcakes

Ingredients

3 1/2 cups cake flour (for those of you with AP flour - measure out all your flour, remove 7 tbsp, replace with 7 tbsp cornstarch - def worth the extra effort!)
2 cups sugar
1 tbsp baking powder
1/2 tsp salt
1 cup butter, room temperature
1 cup milk
4 eggs
2 egg whites
2 tsp vanilla

Steps

- Preheat the oven to 350F. Line muffin cups with paper liners.
- Sift the flour, sugar, baking powder and salt into large, deep bowl.
- Add the butter and 1/2 cup of the milk. Mix on medium speed until dough-like consistency.
- In a separate bowl, blend the eggs, egg whites, the remaining 1/2 cup milk and the vanilla. Add to the batter in 3 additions, mixing for 2 minutes on medium speed after each addition. Scrape down the bowl between additions.

Assembly

-Add 1 heaping tablespoon of batter to liners.  To centre of batter add 1 1/2 tsp of rhubarb filling.  Cover filling with another tablespoon of batter (be sure the bottom batter and top batter meet to seal in the filling).
-Bake for 15-18 minutes, or until skewer comes out clean.
-Let cool completely on wire rack.

*Makes 3 dozen filled cupcakes.

7-Minute Frosting

Ingredients

1 1/4 cups sugar
1/3 cup water

3 egg whites

1/4 tsp cream of tartar

1 tbsp vanilla (I used homemade rhubarb syrup)

Steps

-Add sugar, water, egg whites, and cream of tartar to a large double boiler bowl.  Beat with electric mixer until mixture is foamy (about 1 minute).
-Put bowl over simmering water and beat with mixer until soft peaks form (supposed to be about 7 minutes but it took me more like 14).
-Remove from heat, add vanilla, and continue to beat to thicken frosting (about 2 minutes).
-Let cool completely before using.
