Chewy Brownie Recipe with a Box-Mix

I always have a box of my favorite store-bought brownie-mix in the pantry.  Why?  Because brownie cravings can happen anytime of the day… or night… and one has to be prepared 😉

When I bake brownies in the pressure cooker, since they steam cook instead of bake, it makes them gooey and super fudgy on the inside!  The texture is as if Chocolate Brownies and Molten Lava Cake had a baby 🙂

We LOVE Fudgy Brownies!

My family loves brownies!  We can have them in any season, anytime of the day (ok, I ‘generally’ don’t allow them for breakfast).

My girls and hubby love it with vanilla or mint-chocolate chip ice-cream, drizzled with caramel or chocolate sauce, and I love them as-is.

But there is one thing all four of us are particular about is that they have to be FUDGY!  I’ve been making fudge brownies in the oven for over a decade now. 

But recently, after several delicious batches of Chocolate Lava cake in the Instant Pot, I decided to give chocolate brownies a shot.

For the purpose of this experiment, I used our favorite brownie-mix from Trader Joe’s, and now,  I am excited to try our zillion variation of brownies from scratch. 

Next on my list is my kids’ recipe for 4-ingredient Nutella Brownies! Can’t wait!

Fudgy Brownies versus Cakey Brownies

I must confess, there was a time when I used to think all brownies are the same, till I got a Brownies 101 from my husband, the ‘Chocolate Aficionado’ in our family.

So, there are two kinds of textures in brownies, Cakey or Fudgy.  Regular or Cakey brownies are delicious too, the texture is more ‘cake-like’ though .  That’s because, the ratio of flour to fat is higher. 

So, you would add more all-purpose flour for the same amount of butter and chocolate for a regular brownie.  Some recipes also call for a little baking powder, for a more ‘airy’ brownie.

Then, there are fudgy brownies, which require much less flour and more butter and chocolate.  No baking soda in these.  And the result is a more dense chocolate and chewy-gooey interior.  It’s also flatter as compared to its counterpart.

So, by the end of it, it’s a personal preference.  Make whatever makes you happy! 

Why make Chocolate Brownies in the Instant Pot Pressure Cooker?

In an Instant Pot, the brownies steam cook in a water bath which helps them get that moist and gooey texture. The only thing an Instant Pot cannot do is give it that crisp exterior that you get in the oven. 

Plus, on days when the outside temperature is soaring, I don’t have to turn on the oven to make brownies anymore.

Overall, I don’t think one method replaces the other, and it all comes down to personal preference.

How to Calculate Cook Times for Different Brownie Mixes

If you’re using a store-bought brownie mix, or using one of your go-to brownie recipes, how do you adjust cook time?   Well, there are two big differences in cooking conditions between Oven-Brownies and Instant Pot Brownies:

Size of Pan

First, bake time stated on your box-mix is probably for a different size pan.  Even if you’re using your own recipe, chances are, you’ve been making it in an 8″ X 8″ pan, or a, 9″ X 13″ pan.   

The cake pan that will use for the Instant pot will be smaller, which means more batter-to-pan ratio.    So, you have to increase the cooking time for the batter to cook through.

For example, I use a brownie-mix from Trader Joe’s, that suggests a bake time of 30 minutes for a 8″ X 8″ pan.  For this recipe, I used a 7-inch Springform pan, which is smaller,   So, I need to add about 5 minutes to the suggested 30 minutes.

Texture Difference

Second, oven uses dry heat to bake brownies, whereas, Instant Pot uses ‘steam’.  That adds more moisture to the texture of the batter.  

When I bake in the Instant Pot, I find that my cakes and breads turn out too moist if I stick to the standard baking time.  Adding another 5 minutes of pressure cooking time corrects the texture for my taste.

My Time Calculation Formula

So, overall, this is how I reached the 40 minute cook time for these brownies: Suggested bake time (30 mins) + 5 mins for pan size adjustment + 5 mins for moisture adjustment. 

As you can tell, one size doesn’t fill all here 🙂   There is a little bit of customization required for different types of cakes.

If you find that your brownie batter doesn’t look cooked at the end of 40 mins, seal it, and put it back for another 5 mins or so, depending on the quantity and how underdone it looks.

How to Make Instant Pot Fudgy Brownies

I make this recipe using the the CAKE setting in Instant Pot Ultra, which defaults to 40 minutes of pressure cooking at high pressure.

If you have a DUO model, you can press Manual/Pressure Cook for 40 minutes (high Pressure).  Remember to seal that vent 🙂

Step 1: Melt Butter in the microwave in 20 second increments. Total time may vary depending on temperature of butter and microwave strength.

Step 2: Whisk in room temperature eggs, one at a time.

Step 3: Mix in the brownie mix using a spatula. Gently fold the batter to prevent over-mixing.

Step 4: Grease an oven safe baking pan.  Line it with a parchment base (optional), and pour the batter in.  In this recipe, I used a 7-inch springform pan for a 6 quart Instant Pot.  Cover the pan loosely with some foil or parchment paper.

Step 5: Pour a cup of water in the pot, place a trivet and place the cake pan on top.  For Instant Pot ULTRA: Close lid. Select CAKE button, press START.  For Instant Pot DUO & LUX: Set vent to Sealing position. Press Manual 40 mins (high).

Once cook time is over, wait 10 minutes and then release pressure (NPR 10).  Using silicone mitts, remove the cake pan and remove the foil.  Using a plastic knife, go around the edges of the brownie. 

Release the spring and remove the ring.  For best results let the brownie cool 10 minutes before cutting.

Tips for Making Perfect Chocolate Brownies

  • Always start with room temperature ingredients (butter & egg). Please keep in mind that the time it takes for butter to come to room temperature in summer is way shorter than winter-time.
  • When mixing the brownie-mix, gently fold it in using a spatula. That prevents over-mixing the batter and reduces air-bubble formation in the batter. That is key for the dense texture of the brownies.
  • I prefer to line the bottom of the cake pan with parchment rounds. That results in a guaranteed and mess-free release.
  • For best results, cool the brownies 10 mins after cooking.
