What Goes Into the Pot Today
- 2 large eggs at room temperature
- 2 cups granulated sugar
- ½ cup cocoa powder for that rich chocolate punch
- 1 teaspoon instant coffee granules, dissolved in hot water
- 2 ½ cups all-purpose flour, sifted for fluffiness
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- ½ teaspoon fine sea salt
- 1 cup buttermilk and 1 cup vegetable oil for moisture
- 1 tablespoon vanilla extract, plus extra for caramel sauce

The Exact Process From Start to Finish
First, you gotta preheat your oven to 350 degrees Fahrenheit and grease a 9x13-inch pan. Even though you’ll cook it pressure cooker style, this gets the cake ready for finishing touches.
Next, dissolve instant coffee granules in hot water and let that cool. It really sets the scene for that deep chocolate richness. For equally easy pressure cooker dessert inspiration, check out our Easy Cannoli Cheesecake Bars Recipe.
In a big bowl, whisk those eggs and sugar until they blend smooth and a little fluffy. Then stir in the cocoa powder and coffee mix, taking care to smooth out lumps.
Now, sift together all your dry stuff: flour, baking soda, powder, and salt. Slowly add those dry ingredients to your wet mix in batches. You alternate with buttermilk, gently mixing till just combined and no overbeating.
Pour the batter in your greased baking pan, smoothing the top with a spatula. Pop it in the oven for around 30 to 35 minutes or until a toothpick comes out clean.
Once baked, let it cool in the pan for 10 minutes. Then you transfer the cake to a wire rack to cool completely. When cool, spread caramel sauce, chocolate frosting, and sprinkle those toasted pecans as a final heavenly touch.
Smart Shortcuts for Busy Days
If you’re pressed for time, you can totally skip sifting and just stir the dry ingredients well together. It won’t change the flavor at all.
Another trick is to use store-bought caramel sauce instead of making it from scratch. It works real good and saves serious time.
Toast your pecans ahead in a big batch and keep ‘em in an airtight container. Then just grab when you need a crunchy top. Easy!
That First Bite Moment
When you take that first forkful, you notice the moist crumb that’s soft but holds together just right. You sense the cocoa and coffee whispering sweetly in the background.
Then the caramel sauce hits with a sticky, buttery pull. It melts into the chocolate frosting creating a luscious layer that kinda wraps your taste buds in warmth.

Finally, that toasted pecan crunch surprises you with its salty contrast. It’s like little bursts of nutty fireworks every few bites. The whole things feels like a cozy hug from your favorite dessert.
Your Leftover Strategy Guide
If you got any cake left, you can wrap slices tightly in plastic wrap. This keeps moisture in and stops it drying out. For more dessert storage ideas, see our Cheesecake Bars Recipe.
For longer storage, pop wrapped pieces in the fridge. They’ll last about a week and still taste dang good.
You can also freeze slices sealed in a freezer bag with air pushed out. When you want a treat, thaw overnight in the fridge and enjoy almost like fresh baked.
Your Most Asked Questions Answered
Q1 What if my float valve doesn’t rise properly? Make sure your sealing ring is clean and properly seated. Also check broth depth isn’t too low or too high. These little things help get that good pressure build-up.
Q2 Can I use regular milk instead of buttermilk? You can, but add a tablespoon of lemon juice or vinegar to milk and let it sit for a few minutes. This kinda makes a buttermilk substitute to activate the baking soda properly.
Q3 How do I do natural release? After cooking, just let your cooker sit without opening the valve. The pressure slowly drops on its own, which keeps the cake gentle and prevents it from collapsing.
Q4 Is it okay to double the ingredients? It’s usually better to make a single batch ‘cause pressure cookers work best with certain depth of broth and size. If you double, you might need to adjust cooking time and liquid, which can be tricky.
Q5 My cake is dry, what went wrong? Check if you added too much flour or baked too long. Also confirm you used oil and buttermilk as recipe states. Pressure cookers usually keep moisture but little changes can make a difference.
Q6 Can I swap vegetable oil for butter? Butter changes texture and could make cake heavier. Vegetable oil keeps it moist and tender, which is what you want for that soft bite and gooey caramel moment.
