The pot lid rattles and you know dinner is almost ready. You remember when the kitchen starts filling up with that warm aroma that sticks like a hug. It’s that kinda feeling you get when you realize you’re close to eating something amazing.

Tonight, it’s no different because you’ve got a Matilda Chocolate Cake simmering in the pressure cooker. The steam cues from that trusty gadget tell you it’s working hard for the perfect rise and moist crumb you’re craving.
You recall how easy it is to toss in your ingredients, seal the lid with the sealing ring tight, and set it to work. The quick release makes it slick to open without any stress, and you’re almost done with this chocolate dream.
Why This Recipe Works Every Single Time
- The pressure cooker keeps the cake super moist by using its steam heat, preventing dryness that ovens sometimes cause.
- Quick release method stops cooking at just the right time so you don’t risk overbaking.
- The combination of baking soda and baking powder ensures perfect lift and texture.
- Hot coffee adds that deep broth depth to the chocolate flavor that you’ll actually taste.
- Buttermilk and sour cream keep the batter creamy and tender.
- The sealing ring makes sure no steam escapes, so your cake bakes evenly under pressure.
Everything You Need Lined Up
You gotta start with your dry ingredients ready: 2 cups all-purpose flour, 2 cups sugar, and ¾ cup cocoa powder. Don’t forget the 1 teaspoon salt to balance sweetness and 2 different leaveners: 1 teaspoon baking powder plus 2 teaspoon baking soda.

For wet, you’ll want ½ cup vegetable oil, 1 cup buttermilk, 2 eggs, and 1 teaspoon vanilla. This combo helps keep the cake tender and rich.
Then there’s the boost: 1 cup hot coffee for that amazing depth. You also need ¾ cup salted butter, 1 ½ cups semi-sweet chocolate chips, and ¾ cup heavy whipping cream for the frosting.
To finish, mix ¾ cup sifted powdered sugar, 3 tablespoons sifted cocoa powder, ¼ teaspoon salt, 5 tablespoons sour cream, and 1 teaspoon vanilla into your frosting mix. Better have everything spotted and ready before you even start heating.
The Exact Process From Start to Finish
- First, you’ll wanna grease your pressure cooker insert or a matching round cake pan that fits inside it. Set aside.
- Whisk together flour, sugar, cocoa powder, salt, baking powder, and baking soda in a big bowl.
- Add vegetable oil, buttermilk, eggs, and vanilla to the dry mix. Stir until just combined but don’t overmix or it gets dense.
- Pour in the hot coffee carefully and stir to blend—it loosens up the batter and adds that rich flavor.
- Pour batter into your prepared pan and tap gently to release any big bubbles. Pop it into the pressure cooker insert.
- Seal the lid with the sealing ring in place. Cook on high pressure for 30 minutes. After that, use slow release for about 10 minutes, then quick release to finish.
- Once cool, whip up the frosting by melting butter with chocolate chips. Stir in cream, powdered sugar, cocoa, salt, sour cream and vanilla. Spread it thick or thin, however you like!
Time Savers That Actually Work
- Use pre-sifted cocoa and powdered sugar if you can find em—it saves the extra fuss.
- Skip homemade buttermilk and just add a splash of lemon juice or vinegar to milk before mixing.
- Have hot coffee ready before you start mixing to keep batter smooth and wet right away.
- Put your wet and dry ingredients in separate containers the night before, so you can just dump and mix when you’re ready.
- Instead of separate pans, bake this cake in one deep pan in the pressure cooker and slice it thinner once cool.
Your First Taste After the Wait
You slice through the cake and notice the fudgy, moist crumb that kinda melts as it hits your tongue. That depth from the coffee wakes up your taste buds without overpowering the chocolate you love.
The frosting is velvety smooth, creamy but not too sweet, just enough to balance the bittersweet chocolate chips inside. You sense that sour cream adds a tangy hint you never saw coming but adore.

Together they create a cozy but indulgent experience. You feel that satisfying heaviness in your belly and kinda can’t wait to have another slice but you also don’t wanna finish it too fast.
Smart Storage That Actually Works
- Wrap your cake tightly in plastic wrap then pop it in an airtight container to keep it fresh for a few days on the counter.
- If you wanna keep it longer, refrigerate but let it come to room temp before serving to get back the softness.
- For serious saving, freeze individual slices wrapped in foil and placed in a freezer bag. Just thaw overnight in the fridge or warm a bit at room temp.
What People Always Ask Me
- Can I make this cake without coffee? Yeah you can, but coffee really helps bring out that chocolate richness. If you skip it, try swapping in hot water and a touch of vanilla extra.
- Is the pressure cooker method complicated? Nah it’s pretty straightforward. Just be sure your sealing ring is clean and properly placed and watch steam cues during cooking.
- What’s the deal with slow release? Slow release lets the pressure drop gradually so cake stays tender instead of drying out from quick steam release.
- Can I use another type of oil? Vegetable oil is best cuz it tastes neutral, but light olive or canola oil works if that’s what you got.
- How do I know when cake is done? Use the toothpick trick after pressure cooking and quick release. If it comes out clean or with a crumb or two that's perfect.
- Why is buttermilk important in this recipe? Buttermilk reacts with baking soda and powder to get that fluffy texture and tender crumb you want in your cake.
