Sweet Potato Pecan Pudding Cake

They're lying.  All the people who posted photos of this cake are lying.  You can't dump 2 cups of sweet potato into a regular cake recipe and have it turn out light and fluffy like their photos show.  What you get is what's in that photo above:  a cross between cake and bread pudding.  Kitchen Nostalgia even acknowledged, "The cake was very moist, actually more like pudding than regular cake. I happen to like that, but I know some of my readers would certainly comment on this."  Yet her picture is of a turmeric-colored cake with a little topping.  Not the same recipe.

It's not a bad recipe, necessarily, but it's not "cake" as we're used to having, and as all those people presented.  Especially when they're touting it as "cinnamon roll" cake, further indicating it should be airy.

This turned out fine--- people snarfed it down--- but it certainly didn't come out as desired.  And after comparing the original recipe for plain cinnamon roll cake and this one, I feel confident it wasn't because of my changes.  I had wanted to use half whole wheat flour but didn't have any, so I substituted some coffee flour and some wheat bran, and I changed up the directions a little to be more conventional.  I also halved the recipe, but baked it in a pan that was appropriately sized.

My additions are in strikeout and italics.  Here's what I used:

1 ½ ¼ cups flour 

2 tablespoons coffee flour

2 tablespoons wheat bran

2 teaspoons baking powder

1/4 teaspoon nutmeg 

1/8 teaspoon salt

1 cup cooked sweet potatoes

1/2 cup sugar

1 egg, beaten

1 teaspoon vanilla
1/4 cup butter, melted

3/4 cup milk

Topping:

1/2 cup butter, softened (see note)

1/2 cup brown sugar

1 tablespoon flour

1½ teaspoons cinnamon 

Glaze

1 cup powdered sugar

2½ tablespoons milk

1/2 teaspoon vanilla

1/2 cup chopped pecans

Preheat oven to 350 degrees.  Grease a 10x7.5-inch baking pan.  Sift together the flours, bran, baking powder, nutmeg, and salt.  In a medium mixing bowl, beat sweet potatoes with the sugar. Add the egg and vanilla and mix until combined, then add the melted butter and mix until thoroughly blended and smooth. Add the flour mixture in thirds, alternating with the milk and mixing between additions. Pour batter into prepared pan. Mix all the topping ingredients together until well combined.  Drop evenly over the batter and swirl with a knife. Sprinkle with pecans. Bake cake for 30 - 40 minutes.

I checked it at 25 minutes-- still raw.  At 32 minutes, it had started to swell in the middle.  Removed at 38 minutes.  Skewer came out clean and it had puffed fairly evenly and had started to pull away from the sides, but there was a lot of melted butter and syrup running around the pan.  The syrup firmed up and the butter was absorbed as the cake cooled.

Note:  I'd be inclined to halve the amount of butter in the topping.  It seemed excessive, literally being more like a seasoned butter than a topping.

Conclusion:  The taste was good on this, despite everything.  I had been inclined to reduce the sugar, but my batter had a slight bitter taste (probably my additions) so I used the full amount and it was fine.  I skipped the glaze, though.  If I were to make this again, which I doubt, I would be inclined to cut it up into two-bite pieces and serve them in a bowl with whipped cream.
