A moist, rich cake swirled with caramel and brewed coffee — perfect for lovers of espresso and gooey desserts alike.
Cake:
1¾ cups all-purpose flour
1½ tsp baking powder
½ tsp baking soda
½ tsp salt
1 tsp espresso powder (optional)
¾ cup unsalted butter, softened
1 cup brown sugar
2 large eggs
1 tsp vanilla extract
½ cup strong brewed coffee
½ cup whole milk or sour cream
Caramel Swirl:
½–¾ cup thick caramel sauce
Optional: flaky sea salt for topping
Preheat oven to 350°F (175°C). Grease a 9×13” pan or 8×8” for thicker layers.
Mix flour, baking powder, baking soda, salt, and espresso powder in a bowl.
Cream butter and brown sugar until fluffy. Add eggs one at a time. Stir in vanilla.
Add dry ingredients alternately with coffee and milk. Mix until smooth.
Spread half the batter in the pan. Drizzle ½ cup caramel over it. Add remaining batter and swirl more caramel on top.
Bake 35–40 minutes or until edges are set and golden. Center may be slightly gooey.
Cool 15–20 minutes before serving. Top with salt, whipped cream, or glaze.
Store leftovers at room temp or refrigerate for 3 days.
Serve warm for maximum gooey texture.
Add chocolate chips or nuts for variation.
