This cake is the last one of Birthday Behavior month, and by the time I got to it, I had a problem. I had baked my way through August with a running list of ideas that never made it into a recipe, and there was only one slot left. I wanted a hummingbird cake. I also wanted a chocolate cake. And I very badly wanted something with a real crunch to it. Four recipes had already come and gone, and here I was with three cakes still living in my head and one chance to bake them.
So I stopped choosing and folded them all into one. That is honestly how this recipe came to be, a gathering of half a dozen different ideas that I finally stopped keeping apart. And it worked. It is a cake I loved making and loved eating, which does not always happen at the same time.
The first thing anyone notices is the crunchy top. It is the part your eye goes to before you have even tasted anything. I had come across the idea online, one of those toppings that goes around the internet and lodges itself in your mind, and I promised myself that the next time I made a cake I would try it. This was the chance and I was not letting it pass. So the cake carries two toppings, one on the other. A deep chocolate ganache goes over the cake, and over that goes the crunch, made from cornflakes, melted chocolate, toasted crushed pecans, and a little salt, all stirred together and spread across the top.
The cake underneath is wonderful on its own, though. There are pecans inside it, and banana, and pineapple, all the things I had been wanting to work with. There are also two cocoa powders, a Dutch-processed and a darker one, layered together for depth. It is a great deal at once, and yet it comes out balanced. Chocolatey, certainly, but never so decadent that it overwhelms you.
I will be honest with you about the crunch layer: it is a bit of an acquired taste. It is not something you have to make, and the cake is lovely without it. But if you are someone who lights up at a little extra texture in a dessert, I think you will be very glad it is there. There are toasted crushed pecans in the crumb as well, so the texture runs all the way through. Mostly this is just a fun cake, and I mean that as the highest praise. So much is happening in it, and every bit of it works.
Lessons Learned
The first thing that happened was that my cake domed in the oven. It does that to me sometimes with round cakes, not always, just often enough that I have stopped being surprised by it. The fix is simple. Once the cake has cooled completely, run a cake leveler across the top, or use a long knife and take it as level as you can manage. A flat top makes everything that comes afterward, the ganache and the crunch, so much easier to lay down neatly.
Now, a word for anyone who is not a devoted chocolate person. This cake is close to a triple chocolate, between the dark cocoa in the crumb, the dark chocolate ganache, and the chocolate in the crunch. If that sounds like more than you want, reach for a milk chocolate instead and it will soften the whole thing considerably.
Here is the advice I would most like you to take. Before you commit that crunch topping to an entire cake, make a tiny batch and taste it first. Melt a little chocolate, add a pinch of salt, a few crushed pecans, a handful of cornflakes, stir it in a small bowl, and try it. It takes two minutes. It is a trending topping, not a universally loved one, and I would hate for you to build a whole cake around something you turn out not to care for.
Refrigerating during the frosting process made a real difference too. Ganache will happily run down the sides if you let it, so once the top is covered, put the cake in the fridge. Pull it out, add the crunch layer, and chill it once more so everything sets.
That firm crunch does make slicing a little tricky, especially straight from the cold. Let the cake come back to room temperature before you cut into it, or press through with a firm hand if you are impatient. My favorite discovery was putting the whole cake in the microwave for about 30 seconds. Not hot, just warm, enough to get the chocolate loose again. Once the crunch sets, it firms up like a candy bar, and a little warmth brings the whole cake back to life.
One more note on pans. I baked mine in an 8-inch round buckle pan, which is why the bake time reads the way it does. If you choose a different shape or a shallower pan, adjust your temperature and time to suit the depth you are working with.
And finally, the ganache seized on me. It was the first time that had ever happened to me, and it is exactly as frustrating as it sounds. The chocolate pulls together into one stubborn glob and simply refuses to become the smooth thing you were promised. It happened because I rushed and went out of order, trying to make it quickly. So please, follow the ganache steps as written. They are not difficult, and the order is doing real work. If it does happen to you, add a little milk or heavy cream to loosen it and coax it back. But the surest fix is to not get there in the first place.
How to Make It Your Own
There are so many ingredients at work here that the easiest way to make this recipe yours is simply to take something away. I would not pull out too much, but one change here or there turns it into a different cake entirely.
Leave out the pecans and you still have a beautifully moist chocolate cake. Skip the frosting altogether and it becomes a lovely plain tea cake. Or go the traditional route and finish it with the classic hummingbird frosting, a cream cheese buttercream, which would suit it perfectly. A simple glaze works. Ganache alone works. The crunch alone works.
And if you take the cocoa powder out entirely, you are left with a straightforward hummingbird cake, which is where all of this started in the first place. That is what I love about a recipe like this one. It keeps morphing into whatever you want it to be, with only the smallest change. It is beautiful, it is delicious, and it is gluten-free, gum-free, and soy-free. Have fun with it.
Pro Tip: This cake is at its best fresh, ideally made and served on the same day. Once it goes into the fridge, that top layer sets solid, and it needs to come back to room temperature before it is any pleasure to eat. If you do need to store it, slice it first, before it goes in. That way you can take out a single piece, warm it for a few seconds in the microwave, and let it settle to room temperature, instead of waiting on the whole cake to come around.
Summary Notes:
This chocolate hummingbird crunch cake is a little bit of everything, and that is exactly the point. Banana, pineapple, and toasted pecans in a deeply chocolate crumb, a dark chocolate ganache over the top, and a crunchy cornflake and pecan layer to finish. It is gluten-free, gum-free, and soy-free, endlessly customizable, and genuinely fun to make. If you have been wanting a birthday cake with a little more going on, this is the one.

Recipe Steps
Step 1
Preheat oven to 350°F. Generously butter an 8 inch springform pan.
Step 2
In a large bowl, whisk together the gluten-free flour, almond flour, potato starch, both cocoa powders, baking powder, baking soda, salt, and cinnamon.
Step 3
In a separate bowl, add the eggs, granulated sugar, brown sugar, oil, yogurt, and vanilla extract. Whisk everything together until smooth.
Step 4
Add the dry ingredients into the wet mixture. Stir just until fully combined.
Step 5
Fold in the mashed banana, well-drained crushed pineapple, and toasted pecans until evenly incorporated.
Step 6
Pour the batter into the prepared cake pan and smooth the top.
Step 7
Bake for 55-65 minutes, checking around the 45-minute mark. The cake is done when a toothpick inserted into the center comes out with just a few moist crumbs.
Step 8
Remove from the oven and let the cake cool in the pan for about 30 minutes.
Step 9
Transfer to a cooling rack and allow it to cool completely before topping.
Dark Chocolate Ganache
Add the dark chocolate chips and butter to a heat-safe bowl and set aside. In a small saucepan or microwave-safe measuring cup, heat the heavy cream and granulated sugar until the mixture is hot and the sugar has mostly dissolved. Pour the hot cream mixture directly over the chocolate chips and butter. Let it sit undisturbed for 2-3 minutes to allow the chocolate to melt. Stir until the ganache is completely smooth, glossy, and fully combined. Let it cool for about 15 minutes, or until it thickens slightly but is still easily spreadable. Once the cake has cooled completely, spread the ganache evenly over the top of the cake, leaving a small border around the edge if desired.
Chocolate Pecan Crunch
Add the milk chocolate chips to a microwave-safe bowl and melt in 20-second intervals, stirring between each interval until completely smooth. Allow the melted chocolate to cool to room temperature so it is no longer warm to the touch. Add the lightly crushed cornflakes and toasted pecans, then sprinkle in the salt. Gently fold everything together until the cornflakes and pecans are evenly coated in the chocolate. Spoon the mixture over the layer of dark chocolate ganache while the ganache is still soft, spreading it into an even layer with the back of a spoon. Allow the topping to set about 5 minutes before slicing and serving.
Storage:
This cake is best enjoyed fresh, ideally the same day it is made. If you need to refrigerate it, slice it first and store in an airtight container for up to 3 days. Because of the crunch layer, cold slices set firm, so let a slice come to room temperature before serving, or warm it briefly in the microwave (about 5-10 seconds) and let it settle back to room temperature before eating. An unfrosted cake can stay at room temperature for 1 day.
