This recipe was a complete accident. I was making Cookie Dough Topped Brownies and feeling over-confident in my memory of the brownie ingredients. When I got past the step of stirring in sugar, I realized something was wrong. The batter was much thicker than it should be.
Fortunately, I realized that my mistake was adding 50% more sugar than the recipe called for. Rather than throw everything away at that point, I added 50% extra of every thing else. As a result, I had an extra 9X9 pan of brownies and nothing to do with them…
Until I thought about what was in my freezer. Did you know that buttercream stores very well in the freezer? How about some White Chocolate Buttercream?
And then I looked again. Did you know that mocha ganache also freezes well? I happened to have extra from my Chocolate Chip Cookies with Mocha Ganache…
Do you see where I’m going with this?
Oh that is right, one rich chocolate brownie topped with not one, but two incredible toppings.
Thanks to a small mistake and leftovers from baking, I made Brownies with White Chocolate Buttercream and Mocha Ganache, another delicious dessert for our Thanksgiving with Friends.
Make these. No mistakes necessary.
Brownies with White Chocolate Buttercream and Mocha Ganache
Makes 16 brownies (more if you want small pieces, brownies are very rich)

1/2 cup all purpose flour

2 ounces baking white chocolate
1/4 cup heavy whipping cream

Mocha Ganache
5 ounces semi-sweet baking chocolate

Brownies
Pre-heat oven to 350 degrees
Melt butter and chocolate in large sauce pan over low to medium heat
Stir in sugar
Stir in eggs and vanilla
Whisk in flour until smooth
Pour into a 9×9 pan lined with foil and greased or sprayed with cooking spray
Bake for 20-25 minutes or until knife comes out clean
Buttercream
While brownies are cooling, make buttercream
Combine the white chocolate and whipping cream in a medium saucepan on low-medium heat, stirring continuously
Remove from heat and stir in milk
Refrigerate for mixture for half hour
When white chocolate mixture is cool, finish making the buttercream
Beat the butter until creamy
Beat in confectioners’ sugar until butter and sugar are light and fluffy
Now beat in the cooled white chocolate mixture until buttercream is creamy and light
Spread over cooled brownies and refrigerate until buttercream hardens slightly
Ganache
While brownies with buttercream are chilling, prepare ganache
Chop up the chocolate, coarsely, and prepare extra-strong coffee
Slice up your butter and set aside
Now set up your double boiler; bring water to a simmer in medium pot over low-medium heat
Place heat-proof bowl of chocolate over the pot
Pour the coffee over your chocolate
Continuously stir until chocolate is melted and smooth
Remove bowl from heat and whisk in the butter until creamy
Then allow ganache to cool, stirring occasionally
Ganache is ready when the mixture gets nice and thick
Spread over buttercream layer

wow that is so creative and definitely doesn’t look like a mistake to me! I’d bring extras to work!
Looks amazing – if I had leftover brownies (ha!), I’d probably cut them up small and dip them in chocolate like truffles. I’ve been wanting to do that for a while now. But maybe I’d top them with your white chocolate buttercream first. Maybe.
omg that sounds fabulous!! i kind of want to make another batch of brownies now:-)
This has to be one of the most delicious looking mistakes ever. Now I have to add this to my list of your recipes to try. Slow down, I can’t keep up!
that is how i feel lately, i need a vacation from work just to catch up on all of the recipes i want to try!
You’re right.. extra is better. These look divine. Ahh I love this post. I will have to try this.
i love the word “ganache!”
LOL it always makes a dessert sound more decadent, doesn’t it?
Mistakes like this are the best! I love how pretty they turned out too with the dark and white layers. Plus, the flavor combo sounds like it would be excellent. My favorite mistake was adding one too many eggs to the base of a layered bar cookie so that I ended up turning it into caramel rum cake! That was so cool.
now that is a terrific mistake:-)
What an awesome mistake!
Anything with white chocolate is good with me! These look delicious! I printed it out to put in my recipes I have to try pile.
These look so, so fantastic! I love when mistakes turn into something so good! I want to rush to my freezer and see what I have to add to brownies right now!
I’m so glad you didn’t throw it all away. These look like a fab addition to any table. I can imagine if you presented these to friends they would be ecstatic!
Sometimes the best things truly happen by accident. In fact, I believe that I would call something like this serendipity rather than accident. Glorious.
It was great hanging out with you on Saturday! We definitely need to do something again soon!
yes we do need to hang out again!!
Pretty sure your goal is to make us all gain 100 pounds over the holiday season! These look amazing and all-too irresistible.
lol never;-)
Ooh la la
That’s probably the best mistake ever! These look incredible 
I developed a mild obsession with your white chocolate buttercream frosting after I made your red velvet sandwich cookies on Saturday. I could eat it by the spoonful! (and did).
i am so glad you liked it!!
i dont mind making mistakes like this:) this looks awesome! i love it.
Clearly Id eat extra brownies! I always end up making boo-boos when Im baking, so adding more of other things is like second nature! These look great.
lol i definitely support eating extras:-)
Good to have you back home!
good to be back home:-)
These brownies look unbelievably delicious!!! YUM
wow these look amazing. I definitely need to get more adventurous with my brownie making.
xo
Wow! Brownies with buttercream, swoon. I love how freezer lfetovers save me too. If I had an extra pan of brownies, I would prob just mix in some peanut butter and nutella :p
Wow – way to go on salvaging those brownies! They look tasty! And as for the extra brownie… I’d probably drown it in some ice cream and hot fudge and EAT IT.
I say this is a pretty fantastic “accident”! What a decadent combination of delicious flavors
If there were ever to be extra brownies in our kitchen, I might crumble them and toss them into some homemade ice cream during the last few minutes of churning. MMmmmm.
What a great idea!
I would probably find something peanut buttery to do with extra brownies!
