Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the cake, all you need is a simple yellow or white cake mix—nothing complicated—and your favorite jelly. Strawberry and grape are classics, but you can mix it up to your heart’s content. The jelly is thinned slightly so it seeps perfectly into the cake holes, giving you bursts of flavor in every forkful.

The peanut butter frosting is where the magic happens. Creamy peanut butter blended with soft butter, powdered sugar, and a splash of cream or milk makes a dreamy, spreadable topping. Vanilla extract adds that little extra warmth and depth to the frosting. You can even add some chopped peanuts or fresh berries on top for a little crunch and freshness.

How to Make the Best Peanut Butter and Jelly Poke Cake

Make the Cake

Start by baking your cake according to the box instructions. A 9×13-inch pan is perfect here for even baking. After baking, don’t rush to frost it just yet! Let it cool for about 10 minutes first.

Here’s a fun step: use the handle of a wooden spoon or a sturdy straw to poke holes evenly all over the cake—about an inch apart. This simple trick allows the jelly to soak right into the cake, making every bite juicy and flavorful.

Fill the Cake with Jelly

Warming the jelly slightly in the microwave makes it easier to pour and ensures it fills those holes perfectly. I like to thin it out with a bit of water to help it spread better. Pour the jelly gently over the cake, letting it sink in slowly.

Once the jelly has done its magic, let the cake cool completely before moving on to frosting. This keeps everything neat and lets the flavors meld beautifully.

Whip Up the Peanut Butter Frosting

Softened butter and creamy peanut butter get whipped together until smooth and fluffy. Gradually add powdered sugar, heavy cream or milk, and vanilla extract, beating until the frosting is light and spreadable. If it feels too thick, add a splash more cream—one tablespoon at a time.

Once your frosting is perfectly fluffy, spread it evenly over the chilled cake. For extra flair, sprinkle some chopped peanuts or fresh berries on top, or drizzle a bit of melted peanut butter or extra jelly.

Keep this cake covered and refrigerated for up to 4 days, perfect for making ahead of time. If you want to prep in advance, freeze the unfrosted cake layer for up to 2 months. Just thaw before frosting and decorating.

No reheating needed—this cake is best served chilled or at room temperature, so it’s perfect for warm days or a cool dessert after dinner.
