Need comfort food? Peanut Butter Tandy Cake will make it all better! A soft, butter-y sheet cake is topped with peanut butter and milk chocolate ganache.

Ugh, what a week it’s been. Besides the obvious, I’ve also had my kitchen torn up with construction for what’s beginning to feel like too long. And worst of all: no caffeine.
I rarely ever drank more than one cup of coffee per day, but I have always enjoyed it so much! Sadly, I’ve been advised to lay off completely, after my doctor started noticing some health issues.
I’ve had a headache for ten straight days.
There comes a time in a blogger’s life, where you just have to throw your carefully crafted editorial calendar out the window, and bake what makes you feel good.
Peanut butter tandy cake.
When I was a kid, my mom didn’t bake a whole lot. But she was still big on dessert. Once in a while, we had something special. Like a lemon meringue pie from the freezer section.
But most of the time, it was either cookies from the cupboard, or a candy bar or Tastykake from the convenience store down the road.
Do you know Tastykakes? They’re sort of like Hostess or Little Debbie, but way better. They’re made in my hometown, from real ingredients like butter and eggs. My favorite variety has always been the peanut butter tandy cake, aka the kandy kake.
Still, nothing touches homemade, in my opinion. So when the craving struck, I got out my mixer and preheated the oven.
This cake comes together surprisingly easily, with just a few ingredients you probably already have on hand. The cake is soft and buttery, with a fine, downy crumb that’s so moist it’s almost creamy. There’s a thick layer of peanut butter on top, that melds with the sheet cake in the most delicious way. And it’s all topped off with a sweet milk chocolate ganache.
Nothing could be better. Except, maybe, if you had it with a cup of coffee.
But I’ll be sticking with milk.
