Step-by-step: building the perfect poke cake
- Preheat the oven to 350°F and prepare the chocolate cake batter per box directions. Pour into a greased 9×13 pan and bake until a toothpick comes out with a few moist crumbs.
- Let the cake cool 8–12 minutes. While still warm, poke holes across the surface using the handle of a wooden spoon. Space holes about ¾ to 1 inch apart.
- Warm the peanut butter in short intervals in the microwave until smooth. Stir in the sweetened condensed milk until fully combined.
- Whisk the instant vanilla pudding with room-temperature milk just until blended. Immediately fold the warm peanut butter-condensed milk mixture into the pudding until uniform.
- Transfer the filling into a zip-top bag and snip a small corner. Pipe the filling into each hole so the cake soaks up the mixture. Spread any leftover filling evenly over the top.
- Refrigerate the cake at least 2 hours, or longer, so the filling firms and soaks into the crumb.
- To make the topping, beat softened cream cheese and vanilla until smooth. Add powdered sugar and a third of the heavy cream, mixing on low. Pour in the remaining cream and whip until stiff peaks form.
- Spread the cream cheese whipped topping over the chilled cake in an even layer.
- Warm 1/4 cup peanut butter until pourable. Drizzle across the top and, if desired, swirl lightly with a skewer for a marbled look. Scatter chopped Reese’s cups and Reese’s Pieces over the cake.
- Return to the fridge until serving. Slice with a sharp knife for clean pieces.

Baker’s tips for a moist, gooey result
- Poke while warm: The holes absorb the filling best when the cake hasn’t fully cooled.
- Use a zip-top bag to pipe filling. It’s faster and cleaner than spooning.
- Full-fat dairy gives a richer flavor and better texture.
- If the filling thickens, microwave briefly to loosen before piping.
- Chill overnight for maximum flavor melding and moisture.
Make-ahead, storage, and serving ideas
- Assemble up to 48 hours ahead and keep chilled. Flavors improve with time.
- Keep covered in the refrigerator for up to five days.
- For transport, set the pan level in a cooler bag or box and refrigerate on arrival.
- Serve with coffee, cold milk, or salted caramel sauce for contrast.
