Gooey Walnut Chocolate Cake

Whisk together the dry ingredients and sugar.

Whisk together the wet ingredients until very smooth.

Add the chopped chocolate and hot coffee to a bowl and allow it to stand. Stir after one minute.

Mix together the wet and dry ingredients using a rubber spatula.

Add the coffee and chocolate, then carefully mix to combine. It will be much thinner now.

Pour the batter into the prepared cake pan, then bake until done. Cool the cake completely.

Add the corn syrup, sugar, and butter and cook for 1-2 minutes while bubbling lightly.

Stir in the walnuts and vanilla. Transfer to a bowl to cool completely.

Beat together the butter and powdered sugar. Then, add the cream cheese to combine.

Add the melted chocolate, vanilla, and heavy cream and whip until light and fluffy.

Spread a thin layer of frosting on top of the cake.

Transfer a small amount of frosting to a piping bag (or zip-top bag) and pipe a circle around the edge of the cake.

Fill the center of the cake with walnut caramel. Don't fill past the frosting dam.

Add the remaining frosting on top of the filling and spread and swoop to cover completely. Top with toasted walnuts, if desired.
