I have made this recipe multiple times and it always gets rave reviews. My boyfriend even requested this as his birthday cake! I don’t have a double boiler, but I used a saucepan over low heat to melt the butter and chocolate.
My favorite, very slight variation is to bake as 10-12 cupcakes (no alteration to ingredients) — it makes perfect single portions. Excellent when topped with a small scoop of mocha almond fudge or coffee ice cream (not so much as to overshadow the cake itself). Amazing for being so simple to make.
We love this recipe! Our son is going gluten free because of stomach problems, and we really missed brownies and cakes. No more! This is amazing! And so easy.
