A Decadent Peanut Butter Filling

In the photo, I have filled the cupcakes with peanut butter filling, added some mini chocolate chips, in the center.

I didn't add back the centers,

I used them for making trifles with layers of pudding.

You can just frost over the tops of the cupcakes. Also, there is ice cream and chocolate sauce on top.

Two Layer Cakes

When I make a two-layer cake, I fill the center and spread it out.

Then add the second layer and frost. You can also make a sheet cake, then cut it in half, fill and frost.

Make a Double Batch!

If you want to make a four-layer cake, make two 9 inches split in half and double this recipe for the filling to fill each layer.

To really get the creamiest ever filling, I always use just a touch of heavy cream.

Keep Unused in the Refrigerator Covered 

Of course, I do recommend this cake always remains in the refrigerator until ready to serve with when using cream.

I have used nondairy creamer in the past, just a splash. That is perfect when it's for an outdoor picnic or event to leave it out.

A childhood memory made!

Every time I start to cook, bake or mix anything, my future chef and grandson Antonio, is right there to learn.

Antonio is diehard chocolate and peanut butter lover indeed.

The best memories are made in the kitchen and I really enjoy this!

Delicious Fluffy Cake Filling!

He was ready to eat this before it was even done!

He just couldn't wait to dive into his cupcake.

Not sure if he loved the filling more than the cake! It is so delicious all by itself!

Easy to make Peanut Butter Filling

He loves Olaf from the movie Frozen.

I just print off coloring book pages, frosted the cake with whatever kind of frosting you would like (of course chocolate was his choice).

I then take a toothpick and draw the character on the frosted cake.

Tint the frosting, then fill it in with using cake decorating tools, you can find on my shop with me page in the head of the blog

I sprinkled him with sugar to get a snowy effect. He loved it!

Easy Tips!

  • I also decorate cakes or top of the cupcakes with chopped pieces of peanut butter cups sometimes. It's certainly a sweet tooth's dream cake with that addition!
  • In the video, I don't use the electric hand mixer so you can see just how easy it is to make. I do however use the beater to enhance the creamy texture of this.
  • The easiest way I found to fill the cupcakes is I take an apple corer and remove the middle.
  • Add the filling to a zip lock bag filled with this decadent peanut butter filling. Then just fill the centers with ease!
  • I then top the cakes with my favorite frostings and decorate them to the theme. Sometimes I even drizzle some melted ganache chocolate on top.

Homemade Chocolate Ganache

Melted chocolate and heavy cream equal ganache.

I use around 1 cup of heavy cream to 12 ounces of bittersweet or semi-sweet chocolate chips heavy cream to drizzle over the top.

Heat heavy cream to boiling. Pour over chocolate chips and let sit for 4 minutes without stirring. Whisk until the mixture becomes dark and thick.
