Make the crumble by putting the butter, cinnamon, flour, and both sugars in a small bowl. Mix them together using either your hands or a pastry cutter until they form clumps; you don't wanna get this shit too fine, people. You want it to be crumbly.
For the cake, you're gonna basically start the same way: throw the sugars, flour, baking soda/powder, coffee grounds, cinnamon, and butter in a stand mixer and mix them on low until they're combined.
Whisk together the yogurt and milk in a small bowl and add those to the batter on low with the almond extract and egg. Make sure you do this JUST until it's combined; if you make it too smooth you won't get the crumbly goodness that coffee cake is all about.
Butter up (or non-stick spray up, but that doesn't sound nearly as good) a 9x9 square baking pan and spread the batter in there.
Pour the crumble on top of the batter, then stick the whole thing in the oven for about 30 minutes, until a toothpick comes out clean.
While that's going on, brew up some coffee for the glaze.
Glaze is insultingly simple to make: just pour a couple tablespoons of the coffee into some powdered sugar and stir together with a fork. Too thin? More sugar. Too thick? More coffee. A chimp could do it, and hopefully you're not actually a chimp trying to read this and make coffee cake. You should be making banana bread, obviously.
When the cake is done baking, let it rest for 5 minutes, then put it on a cooling rack till it gets down to room temperature.
Pour the glaze on top in neat little ribbons, and you're all set.
