Hi, bold bakers! When I made microwave mug brownie,
it was a huge success, and it went viral with over six million views.
So I thought to myself, what could be better than a brownie made in the microwave?
Well, how about a whole batch of brownies made in the microwave?
You are not going to want to miss this. The recipe can be found on my website,
biggerbolderbaking.com, along with all of my other microwave recipes.
Okay, let's get started in a saucepan.
Over low heat, add in your water, sugar, and chopped chocolate.
You just want to heat these together until the chocolate melts,
roughly three to five minutes. Once your chocolate is melted,
turn off the heat and set it to the side to cool down.
Now we're going to sift together our dry ingredients.
So in goes our flour, cocoa powder, raising agent.
And some salt, and then just sift all these ingredients together.
The reason that we do this is because cocoa powder can be very lumpy.
You want to make sure you get all those lumps out. And listen, I said cocoa powder.
I did not say hot chocolate powder. Hot chocolate powder is very different.
If you're a bold baker, you're going to need some good quality cocoa powder.
Okay, looking good. So now I'm going to set my dry ingredients aside,
and we're going to finish mixing up our wet ingredients.
So now the reason that we did our chocolate mix first
is because we want it to cool down before we add in the next ingredients.
So into this, I'm going to add in a little bit of flavourless oil.
Now you can use canola oil, vegetable oil, any kind of oil except for olive oil
because that's quite strong. So now next, we're going to add in some eggs.
Now if you do not eat eggs, don't worry.
You can always replace them with flax egg, and that will work really well too.
Now of course, it wouldn't be bigger, bolder baking without
a little bit of vanilla extract, which I absolutely love in brownies.
And then what you want to do is just swiftly whisk all these together.
So now the difference between these brownies and my best ever brownies
is that these are chewy brownies, and those other ones are fudge. I really,
really love these because they still are fudgy, but they have that lovely chew.
Okay, this is all mixed up. Great.
Now we're going to take this and pour it into our dry ingredients.
Then simply whisk the ingredients together until they form a batter.
So now you know what I'm going to say here.
Don't over mix your batter because it will toughen up your brownies.
So just gently fold it together, like so, and then into this.
You cannot have brownies without lovely chocolate chips, so we're going
to scatter in a few of those too, and then just give them a little swirl in.
I'm not sure if you can see this in its entirety,
but this is a really big brownie batter.
They are going to make some huge brownies, so brace yourself. Okay, this is ready.
Now we're going to put it into our mold. So here is my brownie mold.
It is an eight by eight silicone mold, perfect for the microwave.
I'm going to put a link on my website of where you can buy this.
It's really inexpensive.
However, if you don't want to buy one of these, you can always use any eight
by eight inch casserole dish or anything that is safe for your microwave.
So go ahead and pour in all your batter.
As you can see, it's going to go all the way to the top.
That is just fine. Then, just to finish them,
I'm going to scatter a few chocolate chips on top.
Okay, so now it's cooking time. Now you can bake these in the oven if you wish.
Now you can bake them off at three hundred and fifty degrees Fahrenheit
or one hundred and eighty degrees Celsius for roughly thirty to forty minutes.
However, we are going to microwave them,
so I'm going to pop them into my microwave and start them off at around six minutes.
So the beauty of micro baking is that it steams your dessert,
so they end up really moist and soft.
Now, if you haven't seen my other recipes for cakes in the microwave, I've made
a funfetti cake in the microwave, even a carrot cake and a whole cheesecake.
Make sure you go check those out because they're on my website.
So it has been six minutes and it looks like it's almost done on top.
However, I know it needs more time underneath, so I'm going to put it
on for another two minutes to make sure that it is fully cooked.
This timing is based on my microwave, which is twelve hundred watts.
So check the wattage of your microwave because your timing may vary.
So our brownies smell amazing.
Now you can tell when they're done because it's firm on top and there's no wetness.
You also might notice that there's a crack in my brownies.
That's totally fine. It means that it's cooked all the way through.
It is going to be a beautiful texture underneath there.
So now here's what we want to do. We have to resist the urge to eat them.
We're going to leave them in the mold,
let them go totally cool until we're ready to cut them.
So here's a brownie that I made yesterday.
It is nice and cold and ready to be cut. So I'm going to cut it three by three.
Now you can cut it much smaller than that if you want,
but I just want to show you a big brownie.
Oh my gosh, I can feel my knife going through these.
That they're really fudgy on the inside. So check these out.
Total and utter fudginess going on over here. These are cooked to perfection.
If you go too far, you won't get that lovely moist center.
This is exactly the way I like my brownies. I like to serve these warm
with a big scoop of vanilla ice cream on top and chocolate sauce drizzled over.
Oh, that was a mouthful! Oh my gosh, this is so good.
It is super fudgy. It definitely is a little bit chewier. Oh my gosh!
And it has a thin, crispy top.
It's so hard to believe that this was made in the microwave.
Perfect on the inside, crunchy top.
Brownie perfection. These brownies take no time to whip up
and cook in less than ten minutes.
Who would have thought you can make a whole batch of brownies in a microwave?
I'm going to be bold and say I think we've got some real competition here
for my best ever brownies. Thank you so much for watching.
The recipe is on my website,
and I'll see you back here really soon for more bigger, bolder baking.
