Peanut Butter Mousse Cupcake Filling

Pure peanut butter mousse is not only possible but very simple, making it a top choice to fill or frost cupcakes.  The secret ingredient is ricotta cheese which lends volume and helps create a spreadable consistency.  Ricotta adds a subtle complimentary taste to peanut butter and vanilla flavors.

Filling cupcakes may sound difficult but all it really takes is the patience to wait for the cupcakes to cool.  You can frost the cupcakes immediately after filling them.  Use a apple corer to pull a small plug of cake out of the top of each cupcake. Hang onto the plugs to reinsert before frosting.   You can also dig a little hole using the handle of a teaspoon.  Fill using a small spoon or better yet, place the mousse in a plastic sandwich bag, seal and snip off a corner to use as a pastry bag to fill the little cakes.
A plastic baggie makes a great piping bag.

The vanilla (yellow) cupcakes are from an all natural mix that replaces about half of the liquid with ricotta cheese.  The cupcakes taste great and have improved structure for holding fillings. Use your favorite mix or from scratch recipe for 12 cupcakes.

Make the mousse while the cupcakes bake.  Frost with a simple chocolate ganache of chocolate chips and cream.  The technique is included below.

Peanut Butter Mousse
Yield 1 cup, enough for 12 cupcakes or 4 servings

Ingredients
1/2 cup natural peanut butter
1 teaspoon coconut oil*
1/2 cup ricotta cheese, whole milk preferred
1 teaspoon pure vanilla extract
1 tablespoon honey or golden syrup

*skip if using regular peanut butter which already contains an oil

Method
  1. Mix all ingredients together in a small bowl.  Use a whisk to create a smooth texture, whipping for about 30-45 seconds.  
  2. Taste and adjust for sweetness.  You can add more honey or a pinch of salt to bring out a bit more sweetness.  
  3. Use immediately and store any leftovers, covered, in the refrigerator. Use within three days.
NOTE: The cupcakes must be refrigerated since the filling includes dairy.

You can also eat it as a mousse in a small cup with some dark chocolate shavings.


Chocolate Ganache
To make a chocolate ganache to glaze your cupcakes, place 1/3 cup good quality chocolate chips in a microwave safe bowl with enough cream or whole milk to barely cover the chips.  Microwave on high for 30 seconds.  Remove and stir to finish melting the chips into the warmed cream. Cool for 3-4 minutes and spread on cupcakes.  The chocolate ganache will set within a few minutes to a smooth and glossy finish.
