Slow Cooker Triple Chocolate Brownies

Slow Cooker Triple Chocolate Brownies

October is slow cooker month on All Four Burners. All slow cooker, all the time!

Since I don’t want to bore you with solely stews, soups, and chilis, slow cooker month calls for creativity. Daring, some may say.

Hence, the selection of slow cooker brownies. With three types of chocolate.

Despite my distaste for chocolate.

What, you say! How is it possible that someone (somewhat) reasonable and (sort of) rational not adore chocolate?

Give me some credit. I no longer actively dislike chocolate. Now that there is an available abundance of artisanal chocolates — ok, and some that I special-order — I am able to pick and choose which chocolate I allow to pass my lips.

Or I have become less picky. Though I strongly doubt that.

Regardless of my personal idiosyncrasies, brownies are always a solid choice. They are simple to whip up and, when made with high-quality chocolate, (nearly) everyone likes them. Making them in the slow cooker means that these can be baked while the oven is otherwise occupado.

I wasn’t entirely convinced that brownies made in a slow cooker could taste as good as standard ones.

Well, they didn’t. They were a bit more cakey than I prefer. I blame the bit of baking powder. Next time, I will try the recipe without and with less flour to yield a more fudgy texture. Plus, they were drier; in this case, I blame Denver’s climate.

I ended up using two types of Bay Area chocolates in this brownie batch: TCHO (only a few blocks from where I used to work in San Francisco) and Ghirardelli (x2). I substituted bittersweet chocolate chips for semi-sweet. It’s what I had and, besides, there is already plenty of sugar  in the recipe.

Also, the original recipe did not contain a stitch of vanilla. This had to be an oversight. Brownies require vanilla…to survive! While I trust Martha’s people, they need some serious fact-checking help over there.

Slow Cooker Triple Chocolate Brownies

Yield: 24 servings


Nonstick cooking spray
1 1/4 cups all-purpose flour (spooned and leveled)
1/4 cup unsweetened cocoa powder
3/4 teaspoon baking powder
2 teaspoons ground vanilla (or vanilla extract)
1/2 teaspoon coarse salt
1/2 cup (1 stick) unsalted butter, cut into pieces
8 ounces bittersweet chocolate, chopped
1 cup sugar
3 large eggs, lightly beaten
1 cup bittersweet chocolate chips (6 ounces)


Lightly coat a 5-quart slow-cooker insert with cooking spray. Line bottom with parchment paper and lightly coat with spray. In a small bowl, whisk together flour, cocoa, baking powder, vanilla, and salt.
Place butter and chocolate in a medium microwave-safe bowl and microwave in 30-second increments, stirring after each, until chocolate is melted. Add sugar; stir to combine. Stir in eggs. Add flour mixture and chocolate chips and stir just until moistened (do not overmix). Transfer to slow cooker and smooth top.
Cover and cook on low, 3 1/2 hours. Uncover and cook 30 minutes. Remove insert from slow cooker and run a knife around edge to loosen brownies. Let cool completely in insert on a wire rack, about 2 hours. Turn out onto a work surface and cut into 24 pieces.

    How can one Not like chocolate! However, since you are not crazy about chocolate and I am, especially the dark kind, I would have loved to take those brownies off your hands. 😉

      Betty, you know that I’ve never been a giant chocolate fan. I am more than happy to share the brownies with you.

  • I can’t get over how these were made in the slow-cooker. AMAZING!

  • ~Nancy says:

    This recipe just pushed me over the edge and I’m finally biting the bullet and buying a slow cooker. I’m sure I’ll hear it from the other half (he says it will end up in the appliance graveyard, lol), but I have a feeling this one will get used A LOT and make life sooo much easier. Thanks!!!

    • allfourburners says:

      Nancy, hooray! Although maybe you shouldn’t listen to me since I am an appliance junkie. Thankfully, I have the room…and they’re so darn helpful!

  • Jennifer says:

    Is it really triple chocolate brownies? What’s the difference between bittersweet chocolate and bittersweet chocolate chips? Keep in mind, this is coming from someone who is a disaster in the kitchen. But genuinely curious.

    • allfourburners says:

      Jennifer, yep, 3 types of chocolate in this recipe: cocoa powder, chopped bittersweet chocolate, and bittersweet chips. I don’t know if there’s a difference between the last two besides the form into which they are pressed, though I did use 2 different brands.

  • Mindy says:

    I will definitely have to try these…I just made some brownies today. I always add either a little sour cream or greek yogurt to my mix. I find it helps keep it really moist! I’ve never heard of a slow cooker insert…I’ll have to look into that!

    • Cynthia says:

      By insert, they mean the lining of the crockpot. Most of them the insert is removable from the base of the crock. Some of the smaller, or older ones are not, it is a one piece, (well, two, crock and lid) unit.

      • Mindy says:

        Oh…haha…that seems obvious now that you’ve said it! I thought maybe there was some neat cake-like pan thing with a handle that you could just easily pull up and out for “baking” in the crock pot…which would be neat to have!

    • allfourburners says:

      Mindy, I will have to try using sour cream or greek yogurt in brownies. I love the idea!

    I do not have an insert….can I just line my crock with parchment and the spray? I don’t want to ruin all that chocolate…

  • Mary says:

    Love brownies so I want to try these. My question is I have a 6 qt. crock pot so would the time need to be adjusted?

    How much flour and baking powder would you omit to make them more fudgy?

    • allfourburners says:

      Nicole, I’m no expert baker — especially not in a slow cooker. If you try different variations, please let me know how they turn out!
