Ingredients
Method
- Preheat oven to 350°F (175°C) and grease a 9x13-inch pan. Whisk flour, sugar, cocoa, baking powder, baking soda, and salt. Add eggs, milk, oil, and 2 tsp vanilla; mix until smooth. Stir in boiling water. Pour into pan and bake 30 to 35 minutes, until a toothpick comes out with moist crumbs. Cool 10 minutes.
- Poke holes all over the warm cake using a wooden spoon handle. Stir together sweetened condensed milk and caramel sauce, then pour slowly over the cake, letting it soak in.
- In a chilled bowl, beat heavy cream, powdered sugar, and remaining 1 tsp vanilla until stiff peaks form, about 3 to 4 minutes. Spread over the completely cooled cake.
- Sprinkle with toffee bits, slice, and serve. For clean slices, chill at least 2 hours first.
Notes
Let the cake cool fully before adding the whipped cream, or the cream will melt. Chilling the assembled cake for a couple of hours improves the texture and makes slicing easier. Store-bought caramel sauce works great, but if you have a favorite homemade version, use it here.
