What Is a Poke Cake?
A poke cake is exactly what it sounds like—you bake a cake, poke holes throughout, and pour a liquid filling over the top so it seeps inside. In this version, sweetened condensed milk infuses the cake with rich sweetness, making every bite soft and flavorful.
Ingredients You’ll Need
For the Cake:
- 1 box yellow cake mix (plus ingredients listed on the box)
For the Filling:
- 1 can (14 oz) sweetened condensed milk
- 1/2 cup peanut butter
- 1/4 cup milk
For the Topping:
- 1 cup heavy cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
- 4 Butterfinger candy bars, chopped
- 1/2 cup chopped peanuts (optional)
Step-by-Step Instructions
1. Bake the Cake
Preheat your oven and prepare the yellow cake mix according to the package instructions. Pour the batter into a greased 9×13-inch pan and bake until a toothpick inserted in the center comes out clean.
2. Poke the Holes
While the cake is still warm, use the handle of a wooden spoon to poke holes evenly across the surface. Make sure they go deep enough for the filling to seep in.
3. Add the Sweet Filling
Slowly pour the sweetened condensed milk over the cake, letting it soak into the holes. This step creates that signature ultra-moist texture.
4. Peanut Butter Drizzle
In a small bowl, mix peanut butter with milk until smooth and pourable. Drizzle it evenly over the cake.
5. Make the Whipped Topping
In a chilled bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
6. Assemble the Cake
Once the cake has cooled completely, spread the whipped cream over the top in an even layer.
7. Add the Crunch
Sprinkle chopped Butterfinger bars and peanuts over the whipped topping.
8. Chill Before Serving
Refrigerate for at least 2 hours so the flavors meld and the cake sets properly.
