Peanut Butter Filled Chocolate Cupcakes with Easy Chocolate Ganache Recipe

These are the star of any party, and so simple to make since I’ve partnered with OXO, a brand you all know by now that I totally love, as my kitchen is full of their very practical, functional and affordable products. They supplied the Baker’s Decorating Tool, Muffin Pan for this post. All opinions are my own. These are awesome products.

Oxo is Donating Money to Cookies for Kids’ Cancer in exchange for recipe post of Peanut Butter Cupcakes

I baked these in honor of Cookies for Kids’ Cancer.  Oxo will be donating $100 to Cookies for Kids’ Cancer for each blog post (up to their $100,000 commitment*). I participated last year with these amazing salted chocolate caramel cookie bars and was happy to do it again.

In order to participate, Oxo allowed me to choose from a few different sets of baking products. I chose the muffin/cupcake set and I’m glad I did.  To my great surprise I also ended up falling in love with their silicone muffin cups (using them to freeze pesto, and to bake these keto egg biscuits.  I was so impressed with the silicone, I ordered a set for a friend (Nothing sticks and they are easy to wash, unlike many other silicone cups).

The Oxo muffin pan is a commercial grade that has easy clean release and square rolled edges making it easy to take out of a hot oven without putting my pot holder in a cupcake! It does not come with the silicone cups. They are sold separately.

The OXO Baker’s Decorator Tool  comes with two couplers, six stainless  large and small tips and a tip for filling cupcakes. .The unique trigger provides a smooth stream of icing for clean lines, and the comfortable handles ensure a steady grip and protect icing from warm hands.

I was inspired by the filling tip and decided to fill my chocolate cupcakes with peanut butter frosting.

You can also make this recipe with a piping bag.

The Peanut Butter Filled Cupcakes Process

This couldn’t be easier. You can use the larger end of the tip to remove some of the cupcake, then just fill away. Or you can just fill without removing any cupcake. I removed some because I wanted a lot of filling.

You can see I played around quite a bit with the various tips.

There are two kinds here. I made a combination of gluten free chocolate cupcakes and regular chocolate cupcakes. I used the OXO Decorator Tool to fill and to frost. There’s a low carb chocolate cupcake version here. 

Peanut Butter Filed Cupcakes

My Regular Chocolate Fudge Cupcake is one of the most popular here at Spinach Tiger.

The Gluten Free Chocolate Fudge Cupcake is wonderful and that recipe is here along with a chocolate fudge frosting.

The regular Chocolate Fudge Cupcake is incredible, but makes 4 dozen cupcakes (great for parties).  I’ve listed it here again making only two dozen mid-sized cupcakes for your convenience.

The Peanut Butter Frosting recipe is here.

The Easy Chocolate Ganache Recipe

You can make this easy chocolate ganache recipe a few different ways.

It all depends on how thick or how glossy you want it. If you want it glossy, you add butter. I tend to not add butter unless I’m making a cake. Instead I use a high fat chocolate (70%).

Use 8 ounces of high quality chocolate for every cup of heavy cream. If using butter, use 1 tablespoon. 

In this recipe, I halved that and had enough because I didn’t use a lot of the ganache, relying more on the frosting.

Notes

The recipe makes 24 small-sized, NOT MINI) cupcakes. Adjust your frosting accordingly. If you are making filled cupcakes, the peanut butter recipe should be enough. If you are topping the cupcakes (not filling), you will need to double the recipe.
Regarding the chocolate ganache, a little goes a long way.
