I feel lost with all these new abbreviations and acronyms. It makes me feel old and outdated. And in case you’re wondering, here’s what the foreign language above means: Ask Me Anything, Read Between The Lines, Fear of Missing Out, To Be Honest, You Should Know, Shaking My Head, Fixed That For You. I’m not a fan of all this internet slang. The list continues to grow everyday and I’m trailing far behind. For the most part, it confuses me more than it makes communicating easier. When I text message friends, I spell words out completely, use punctuation when needed, and over use exclamation points. If that makes me uncool, so be it. I prefer to stick to the easy abbreviations are super straight forward. Take PBJ (or PB&J). We’re all on the same page when it comes to that meaning, right? Peanut Butter Jelly Cake Components Banana Cake Peanut Butter Frosting Fruit Jam The banana cake uses the same cake recipe from this peanut butter banana bacon cake. It is strong, yet moist cake. It is perfect for stacking! The cake layer may be baked ahead of time and stored in the freezer up up to a month. The smooth and creamy peanut butter frosting is absolute perfection. Best of all, it’s super simple to make. Beat together butter, peanut butter, and confectioners’ sugar. Add a little bit of heavy cream to achieve your desired consistency. As with most baked goods and desserts, smooth homogenous peanut butter like JIF or Skippy works best for this recipe. Natural peanut butter may cause the frosting to separate when chilled. Use your choice of fruit jelly or fruit jam. The cake photographed in this post uses raspberry jam. Choose seeded or seedless version. Any fruit jam will work. If you’re feeling decadent, swap in Nutella or speculoos cookie butter!

You will end up with four banana cake layers. Place one cake layer on cake board or serving plate a top a cake turntable. Spread a layer of raspberry jam over cake using a mini offset spatula or the back of a spoon. Spread a layer of peanut butter frosting over raspberry jam. TIP: Use an ice cream scoop (or cookie scoop) to easily portion out the frosting. Add second cake layer. Repeat spreading jam and frosting. Continue and repeat with third cake layer. Add fourth cake layer on top. However, do not add jam to the final fourth layer. Crumb coat the tops and asides of assembled cake with peanut butter frosting. Place in the fridge for 15 minutes to allow frosting to harden. Add thicker coat of frosting all over the cake. Fruit Jam Options I prefer my peanut butter jelly sandwiches with raspberry jam. This cake recipe works with any fruit jam of your choice. Go with grape, strawberry, apricot, or blueberry jam. If you’re interested in homemade jams, try these out: Homemade Raspberry Jam Fig Jam flavored with vanilla bean Quick Chia Strawberry Jam Blueberry Refrigerator Jam Cake Decoration Ideas There are many ways to decorate layer cakes. Sky is the limit! Choose to go as minimal or as extravagant as you would like. I decorated the assembled banana peanut butter jelly cake with crushed honey roasted peanuts and crushed freeze dried raspberries. Choose to go the minimalist route and try the “naked cake” look like this coconut cake. Or, go the traditional route with sprinkle topping like this classic chocolate cake. Slicing and Serving Cake It is much easier and much cleaner to slice a cold cake! However, cake tastes better is more flavorful when served at room temperature. Slice banana peanut butter jelly cake cold straight out of the fridge. For best results, use a sharp chef’s knife (8-inch or 9-inch knife). Allow cake slices to sit at room temperature for 20-40 minutes to soften. Time depends on the ambient temperature of the room. The chilled cake needs to warm up. During this resting period, the cake and buttercream will soften. This layered 6-inch cake serves 10. For extra decadence, serve peanut butter jelly cake slices with a scoop of vanilla ice cream! Cake Storage Instructions Full assembled frosted cake may be stored in the fridge for up to 48 hours before serving. Take note of any scents or aromas inside your fridge. The buttercream may absorb those flavors. For extra protection, store cake in a cake box (either standard cardboard bakery box or an airtight container). Once sliced, store cake slices in an airtight container for up to three days. Keep in an airtight container to prevent cake from drying out. Also, to prevent cake or buttercream from absorbing any fridge aromas/flavors.

Amanda @ Cookie Named Desire says: August 28, 2016 Oh my gosh, those abbreviations. Thank you for explaining them! I had no idea what some of them were! I just learned what ICYMI meant (in case you missed it) and now I find myself sometimes using it to make myself feel hip. It doesn’t work. But this cake. This cake is seriously amazing. Even just the way you decorated it. I can’t even imagine how great it tastes. Reply
amanda @ fake ginger says: August 28, 2016 Prettiest cake ever! I can’t tell you how many times I’ve seen an abbreviation on Twitter and had to google it. Nothing makes me feel older. Reply
Becky @ The Cookie Rookie says: August 29, 2016 Your cakes always blow me away and this is no exception! Completely delicious and I need it now! Reply
Becky says: February 10, 2017 This is probably a really stupid question but would these cakes freeze for me to defrost them later on for icing? It looks gorgeous and I want to make it for the other half for his birthday but won’t have time to bake and ice during the week so was hoping to do the baking over the weekend. Reply
Maryanne Cabrera says: February 10, 2017 Hi Becky, you can make the cake layers ahead of time. Make the cake as directed, let them cool to room temperature, and then tightly wrap in plastic wrap and store in the freezer. I suggest making the icing/frosting the day you plan on assembling the cake. I hope that helps!
Lauren - the little lake cottage says: March 6, 2019 This recipe looks amazing! I have a kiddo with some special needs and PB&J is one of the only things he eats constantly. I am excited to make this for him. Thanks so much for sharing!!! Reply
