In Mistletoe in Juneau, Declan owes Danni an apology. So he walks into his mom’s bakery and asks her for “a really good cake recipe—as simple as you’ve got.” His mom gives him this one. He’s a little doubtful about the “secret ingredient”—mayonnaise—but the cake is delicious, and Danni forgives him immediately. Even if you’re like Declan and don’t have any baking experience, this moist chocolate cake will win anybody over.

CAKE

  • 2 cups all-purpose flour
