Sous Vide Funfetti Cupcakes

Ingredients for 12

• 12 ounces (3 sticks) unsalted butter, at room temperature

• 3/4 cup (150 grams) granulated sugar

• 2 large egg whites

• 3 tablespoons (15 ml) vegetable oil

• 1 tablespoon plus 1/2 teaspoon (17 ml total) vanilla extract

• 1 1/4 cup (150 grams) unbleached cake flour

• 1 teaspoon (5 grams) baking powder

• Salt

• 1/2 cup plus 1 tablespoon (133 ml total) whole milk

• 2 (1.75-ounce) jars rainbow sprinkles (about 2/3 cup)

• 2 cups (250 grams) confectioner's sugar

Directions

• 

  Step 1

  Set the Anova Sous Vide Precision Cooker to 195ºF (90.6ºC). Generously grease 6 half-pint canning jars with non-stick oil spray or butter.

• 

  Step 2

  Combine 1 stick butter and granulated sugar in the bowl of a stand mixer fitted with a paddle attachment. Beat the mixture on medium-high speed until light and fluffy, 3 to 5 minutes.

• 

  Step 3

  Beat in the egg whites one at a time until combined. Beat in vegetable oil and 1 tablespoon vanilla until smooth.

• 

  Step 4

  In a medium bowl, whisk together flour, baking powder, and a generous 1/4 teaspoon salt.

• 

  Step 5

  With the mixer on low speed, add the flour mixture in 3 additions, alternating with the 1/2 cup milk. End with the flour mixture and mix until just combined.

• 

  Step 6

  Add 1 jar (1/3 cup) sprinkles and mix until just combined.

• 

  Step 7

  Divide the batter between the prepared jars. Each jar should be no more than half full. Wipe off sides and tops of jars using a damp towel. Firmly tap jars on the counter to remove air bubbles.

• Step 8

  Place lids and bands on jars and seal until just tight (do not over-tighten jars; air will still need to escape). Place jars in water bath and set the timer for 3 hours.

• Finishing Steps

• 

  Step 0

  When the timer goes off, remove the jars from the water bath. Place on a cooling rack. Carefully remove the lids. Let the cakes cool to room temperature.

• Step 1

  Meanwhile, prepare the frosting: Combine remaining 2 sticks butter and confectioner's sugar in the bowl of a stand mixer fitted with a paddle attachment. Beat the mixture on medium-high speed until light and fluffy, 3 to 5 minutes.

• 

  Step 2

  Add remaining tablespoon milk, remaining 1/2 teaspoon vanilla, and a pinch of salt. Continue to beat on high speed until mixture is very light in color and fluffy, 3 to 5 more minutes. Reduce speed to medium-low and add 2 tablespoons sprinkles. Mix to combine.

• 

  Step 3

  When the cakes are cool, run a knife around the sides of the jars and carefully un-mold cakes. Using a very sharp knife, slice each cake in half horizontally to form cupcakes. Transfer to a serving platter and pipe frosting on top of each cupcake. Top with remaining sprinkles. Serve.
