matcha fudge sheet cake


happy long weekend!!!! i am so looking forward to relaxing outside, barbecuing, taking a little break from work & drinking way more ice coffees then one person should. it looks like the weather isn't going to be as hot as it was these past couple days here, but lets just cross our fingers the rain holds off for us. now let's talk about this cake!

remember sheet cakes? can we please make these popular again! i feel like in the 90s all i ever did was make cake mix sheet cakes & load them up with rainbow chip frosting. then as my skills progressed, i left behind the simple sheet cake for fancy frosted layer cakes. i forgot how simple & delicious these cakes are to whip up! even the rose frosting took no time at all. bonus points: you don't have to remove them from the pan & pray it doesn't break in the process. the base of this cake is matcha fudge & the frosting is a pure matcha buttercream. because it is a fudgey cake (kind of like a cross between a cake & a brownie) i wouldn't use this recipe for layer cakes! it is so dense, chocolatey & matchay you are going to LOVE it. plus it all whips up in one bowl! for the matcha powder i use aiya matcha's cooking grade blend so the flavours don't get lost when it is mixed with other ingredients!
