Ingredients
- 1 box (15.25 ounces) yellow or vanilla cake mix, plus the ingredients listed on the package
- 1 package (3.4 ounces) instant vanilla pudding mix
- 1 cup creamy peanut butter
- 1 container (8 ounces) whipped topping, thawed
Note: The cake mix requires additional ingredients, usually eggs, oil, and water. These are prepared according to the package directions and are not counted among the four main ingredients.
Instructions
1. Bake the Cake
Preheat the oven according to the cake mix package instructions.
Prepare the cake batter as directed on the box. Pour it into a greased 9-by-13-inch baking dish and bake according to the package directions, until a toothpick inserted in the center comes out clean.
Remove the cake from the oven and allow it to cool for about 10 to 15 minutes.
2. Poke the Cake
Using the handle of a wooden spoon or a thick drinking straw, poke holes throughout the warm cake.
Space the holes approximately 1 inch apart, making sure they reach most of the way through the cake without going all the way to the bottom.
3. Prepare the Peanut Butter Filling
In a large bowl, whisk the instant vanilla pudding mix with 2 cups cold milk until it begins to thicken.
Add the creamy peanut butter and whisk until smooth and fully combined.
The filling should be thick but pourable. If it becomes too thick, whisk in a small splash of additional cold milk.
4. Fill the Cake
Pour the peanut butter pudding mixture evenly over the cake.
Use a spatula to spread it across the surface, encouraging the filling to settle into the holes.
Gently tap the baking dish on the counter to help distribute the filling.
5. Add the Whipped Topping
Allow the cake to cool completely, then spread the thawed whipped topping evenly over the surface.
Cover the dish with plastic wrap or a lid.
6. Chill and Serve
Refrigerate the cake for at least 4 hours, preferably overnight.
Once chilled, cut into squares and serve cold.
Tips for the Best Peanut Butter Poke Cake
- Poke the holes while the cake is still slightly warm so the filling can settle into them.
- Use creamy peanut butter for the smoothest filling.
- Choose instant pudding rather than cook-and-serve pudding.
- Make sure the pudding mixture is pourable enough to fill the holes.
- Let the cake cool completely before adding the whipped topping.
- Chill thoroughly before slicing so the layers have time to set.
- For neat slices, wipe the knife between cuts.
Easy Variations
Chocolate Peanut Butter Cake: Use chocolate cake mix instead of yellow cake for a classic chocolate and peanut butter combination.
Extra Peanut Butter Flavor: Sprinkle chopped peanut butter cups over the whipped topping. This is an optional addition.
Chocolate Drizzle: Finish with a drizzle of melted chocolate or chocolate syrup.
Crunchy Peanut Butter: Use crunchy peanut butter for extra texture.
Salted Peanut Butter Cake: Add a light sprinkle of flaky sea salt before serving.
What to Serve with Peanut Butter Poke Cake
This cake is rich and creamy, so it pairs beautifully with a simple cup of coffee, cold milk, or unsweetened tea.
For a special dessert presentation, serve each slice with a few chocolate shavings or chopped peanuts.
It is especially delicious at birthday parties, potlucks, family dinners, and casual weekend gatherings.
Storage Instructions
Store leftover cake covered in the refrigerator for up to 4 days.
Because the cake contains pudding and whipped topping, keep it refrigerated and do not leave it at room temperature for more than 2 hours.
Freezing is possible, although the whipped topping and pudding layers may change texture slightly after thawing. For the best results, enjoy the cake fresh from the refrigerator.
Frequently Asked Questions
Can I make Peanut Butter Poke Cake the day before?
Yes! This cake is actually better when made ahead. Refrigerating overnight gives the peanut butter filling time to settle into the cake and makes each slice extra moist.
Can I use homemade whipped cream?
Yes. Use stabilized homemade whipped cream if you want it to hold its shape for several days.
Can I use chocolate pudding instead of vanilla?
Absolutely. Chocolate pudding creates a richer chocolate-peanut butter dessert.
Why is my pudding filling too thick?
Instant pudding thickens quickly. Whisk in a little additional cold milk until it reaches a consistency that can be poured and spread over the cake.
Do I need to refrigerate poke cake?
Yes. The pudding and whipped topping require refrigeration to maintain freshness and food safety.
Can I use natural peanut butter?
Regular creamy peanut butter is recommended because it has a more consistent texture. Natural peanut butter can separate and may make the filling less smooth.
