Mia Bakes: Cinnamon-Coffee Crumb Cake

 A while back, I've tried making a coffee loaf cake following this Korean youtuber HojuGyver's mocha-ppang recipe, but it turned out so dry, dense and lacking in coffee flavour overall, it was quite a huge disappointment. 
But as y'all know, other than chocolate, my one other true love is actually coffee and there's no way I'm gonna give up on getting a recipe that yields me a good coffee cake....
Well, I'm referring to the UK's version (literally a coffee-flavoured cake) and not the American version (any flavoured cake, but usually NOT coffee, that you typically eat while having a cuppa coffee).

And so, I found Claire Saffitz X Dessert Person and her recipe for a coffee coffee cake.
Yay! <3

So let's get over with the ingredients to get started! 

For 1 standard loaf cake, you'll need: 

Cake:
230g all purpose flour
1 1/4 tsp baking powder
1/4 tsp baking soda
1/4 tsp salt
90g plain yogurt
75g unsalted butter
25g vegetable oil
60ml strong coffee **see note below
50g castor sugar
30g brown sugar
2 eggs
1 tsp vanilla extract

Crumb Topping:
80g all purpose flour
50g brown sugar
1 tsp ground cinnamon
55g unsalted butter (soften at room temperature)
1/2 pack 3-in-1 coffee mix sachet

Ribbon:
1 1/2 tbsp brown sugar
1 1/2 tsp ground cinnamon
1/2 pack 3-in-1 coffee mix sachet

recipe adapted from Claire Saffitz x Dessert Person's Coffee Coffee Cake

**for my coffee, I've added 60ml hot water to a sachet of Gold Kili Traditional Kopi-O and another sachet of SUPER 3-in-1 Reduced Sugar.
This is already a GREATLY reduced-sugar recipe, so do not try to reduce anymore sugar from your cake batter. In fact, you can do with a little more sugar in your cake batter for better flavour (Eg, using normal or rich 3-in-1 coffee mix sachet instead of reduced sugar).

First up, the streusel crumb toppings. In a small bowl, add in all the crumb topping ingredients and work it with your fingers until all the butter has been rubbed into the dry ingredients and the mixture resembles wet muddy sand. You would want to keep the chunks on the smaller side (although I know it's tempting to have big chunks of streusels) such that they won't crumble off the cake easily as you cut into them later on. Then, set the bowl aside in the fridge (to firm up) as you move on to the ribbon mixture. 

In another small bowl, add in the brown sugar, ground cinnamon and the remaining 1/2 sachet of the coffee mix and give it a quick toss to combine. Then, set it aside. 

Now, in a large bowl, add in the soften butter and sugars and whisk until the butter turns pale and fluffy. Then, crack in the eggs, 1 by 1 and mixing until fully incorporated with each addition, before adding in the oil, yogurt and vanilla extract. Mix well. Then, add in the cooled coffee and mix well. You may find some "curds" of yogurt floating around in the mixture at this point, but don't worry. It'll all be fine. 
Finally, sift in all your dry ingredients (flour, salt and leavening agents) and fold with a spatula or wooden spoon until just combined. 

Then, fill your prepared loaf pan (greased and lined with parchment paper) with half of the cake batter and level it out as best as possible before sprinkling the sugar-cinnamon-coffee dry mixture all over the surface. Then, top the loaf pan up with the remaining half of the cake batter and level the surface off before topping it up with the chilled streusel crumb toppings. Give the loaf pan a few solid taps on the counter to get rid of any air bubbles in the middle before baking it in the oven preheated to 175 degree Celsius for about 40-45 minutes, until a toothpick inserted in the middle comes out clean. 

When the baking time went beyond the 30 minute mark, I was starting to get paranoid that my crumb toppings are gonna burn, but they obviously didn't. 

But as all ovens behave differently, you may want to keep a close eye on yours and cover the top with a piece of aluminium foil to prevent the streusel crumbs from over-browning/burning. 

And I obviously didn't do a good job levelling out the surface of my cake batter before I sprinkle in my ribbon. HEH! 

So while the cake is on the denser side like a solid pound cake, it's still relatively moist due to addition of the yogurt (or you may use sour cream too) and packed full of coffee and cinnamon flavour, an epic combination. (I personally love adding cinnamon to my coffee, YUMS!). 

Do give this recipe a try if you're also a coffee fan like me!

Till then,
