Birthday cakes to pair well with beer

Hope the birthday celebration went well!
Meanwhile,
1) what cakes/desserts did you serve,
2) would you recommend them again
3) with which beers?
Always willing to do taste tests with more info ;)...

Ovenly Bakery has a stout cake that will BLOW YOU AWAY....they use it in their blackout cake, but I've used it with so many things. It's dense enough that you can bake it as a sheet cake and really do anything with it. I've slathered it with Irish cream buttercream, bourbon caramel, cream cheese frosting, earl grey-milk chocolate ganache, etc.

Appologies if this is too late, but: There's a simple Nigella Lawson Almond Clementine Cake that I love. It is citrus-y but neither sweet or sour so I think it would go with a lot of beers, and it is rich (from almond meal and eggs) without the heavy mouthfeel of butter/oil so if there is a beer it isnt great with water in between bites/drinks should be sufficient not to interfere with the beer (which sounds like the star). Add a tablespoon or two of chopped fresh rosemary to add an extra pine-y note to play with the hops if you can!

A banana bread could pair well, depending on the notes in the beer.

Box cake mix in a Bundt pan, sub red wine for water. Glaze with a brandy/powdered sugar slurry. Beer with a shot chaser.

Nigella Lawson makes a delicious chocolate cake with Guinness, and cream cheese frosting. Should be great with beer. http://cooking.nytimes.com/recipes/1875-chocolate-guinness-cake

Creme brulee or a fruit strudel (defining "cake" loosely as a sweet baked dessert) to go with a hoppy beer.
See Observer website (Britush newspaper) March 2015 article for more ideas.

Flourless choclate cake?

For a dark beer like a port I love a spice cake, but for hoppy IPAs I'd consider a lemon cake--citrusy/herby.

Gingerbread (with or without chocolate: https://food52.com/recipes/16187-gingerbread-beer-bundt-cake-with-chocolate-glaze)
