Peach Jelly-Filled Banana Bread Bars

I love a good jelly-filled danish or donut. Plump, puffy, and sporting a sweet surprise in the middle.

I’ll also never tire of banana bread. These bars are part jelly danish crossed with ultra moist banana bread.

The batter for the bars is fast and easy to make. Multiple ingredients are combined at once, in one bowl, are are whisked together. Begin by melting one stick of butter, add an egg, sugars, peach yogurt, and vanilla extract. I chose a peach theme for this recipe, both the yogurt and jelly used are peach. But if pineapple, mango, strawberry, or a mix-and-match combination of various yogurt and jelly flavors is what you have or prefer, go with that. Virtually any fruity combination will work with bananas. They’re such a great canvas.

Fold in mashed bananas, flour, baking soda, and one packet of dry instant vanilla pudding mix to the batter. Pudding mix has a high amount of cornstarch in it, and my favorite chocolate chip cookie recipe calls for cornstarch. The cookies are soft, tender, and moist; and the cornstarch in the pudding mix does the same thing for these bars, rendering them fall-apart soft. Plus, the vanilla pudding adds an extra layer of vanilla flavor and I can never get enough vanilla.

Turn out the batter into a 9-by-9-inch pan, and although I haven’t tried it, I’m sure making this as a 10- or 12-cup Bundt cake would work well. Lightly smooth the surface of the batter and add about fifteen teaspoons of jelly, or about one-third of a cup. Dollop little blobs of jelly onto the surface in a random pattern, evenly dispersing the mounds, until the surface is well-covered in sweet, sticky jelly.

Marble and swirl the jelly with a table knife, going up and back, zig-zagging around. It doesn’t matter if the swirls are visually neat and pretty because as the bars bake, they turn a rich and golden amber hue, and the swirly pattern isn’t discernible. The jelly is for taste, and to lend moisture to the bars, rather than for visual effect.

Baking times will vary due to the moisture content in the bananas and in the jelly, jam, or preserves used; as well as climates, oven variances, and personal preferences. About forty minutes is the low end but I could envision up to one hour at the high end. I recommend covering the pan with foil  midway through baking if your bars seem to be browning quickly, since the sugars in the jelly are prone to caramelizing. My oven here in Aruba runs hot and has a tendency to superficially brown things before the interior cooks through, and baking in humidity compounds the issue, so I covered my pan halfway through baking. Even when they’re done, they’re gooey and dense, and a toothpick test won’t likely come out clean.

After allowing the bars to cool, I made a simple vanilla glaze with melted butter, confectioners’ sugar, and vanilla extract. The bars are plenty sweet on their own and don’t need a glaze, but glaze and frosting makes my world go round, so I happily drizzled away.

The bars may be stored at room temperature or in the refrigerator. They have the density of a fugdy brownie, which I prefer served chilled, and I like these bars chilled, especially because it’s hot and humid here. But there’s a case to be made for serving them warm, especially in cold weather climates this time of year. Freshly baked, still warm banana bread is one of life’s great pleasures.

The banana flavor dominates, as I find bananas have a tendency to do whenever they’re present, but hints of peach jelly come through as a complementary background flavor.

Between the butter, bananas, yogurt, pudding, and jelly, these bars are dense, thick, and gooey. Nothing light, fluffy, dry, or airy about these. This is comfort-food; aromatic and rich, causing one to go back to the pan to even-out the rows with a fork at 1am, if you know what I mean.

This is melt-in-your-mouth, jelly-filled, drippy-glazed comfort at it’s finest.

Prep time
Cook time
Total time
The bars are part jelly danish crossed with ultra moist banana bread. Peach yogurt is used in the batter and the bars are fall-apart soft and moist. Peach jelly is swirled throughout before baking, boosting the peach flavor, moisture, and sweetness. These bars are dense and rich like a fudgy brownie. There's nothing airy, cakey, or light about them. They're melt-in-your-mouth, jelly-filled, drippy-glazed comfort-food at it’s finest.
Serves: One 9-by-9 inch pan, 9 generous squares
  • For the Bars
  • ½ cup unsalted butter, melted (one stick)
  • ¾ cup granulated sugar
  • ¼ cup light brown sugar, packed
  • 1 large egg
  • 6 ounces peach, pineapple, or vanilla yogurt (one standard-sized small container, about ¾ cup. Greek yogurt is ideal, sour cream may be substitued; don't use thin, runny, lite or 'diet' yogurt)
  • 1 tablespoon vanilla extract
  • 1 to 1¼ cups mashed ripe bananas (2 medium bananas)
  • one 3.4-ounce box instant vanilla pudding mix (not Cook ‘n Serve; banana-flavored pudding may be used to boost the banana intensity)
  • 1¼ cups all-purpose flour
  • ¾ teaspoon baking soda
  • ½ teaspoon salt, optional and to taste
  • about 15 teaspoons peach jelly (about ⅓ cup, jam or preserves may be substituted; pineapple, mango, orange or similar flavors may be substituted)
  • For the Vanilla Glaze, optional
  • 2 tablespoons unsalted butter
  • ¾ cup+ confectioners’ sugar
  • ½ teaspoon vanilla extract
  1. For the Bars - Preheat oven to 350F, line a 9-by-9-inch pan with aluminum foil, spray with cooking spray or grease and flour the pan; set aside. In a large microwave-safe mixing bowl, melt the butter, about 1 minute. To the melted butter, add the sugars, egg, yogurt, vanilla, and whisk to combine. Add the bananas and stir to incorporate.
  2. Add the dry pudding mix and stir to incorporate (You are not making pudding; simply add the mix as a dry ingredient. The pudding mix could be replaced with 1 to 2 teaspoons cornstarch, and about 2 to 3 tablespoons flour. Like any dough or batter, there is some flexibility with how to make up for eliminating three ounces of dry mix). Add the flour, baking soda, salt, and stir until just combined, taking care not to over-mix or bars will be tougher as the gluten will over-develop. Pour batter into prepared pan, smoothing the surface with a spatula.
  3. Add one teaspoon of jelly at a time to the top surface of bars, creating a surface dotted with little jelly blobs, dispersed randomly over the surface. With a table knife, swirl and marble the jelly through the batter using a zig-zag pattern going up-and-back, side-to-side a few times to disperse the jelly. It doesn't matter if the swirls are pretty or neat because while baking, it all turns into a golden shade of amber and melts together and you can't see the swirls; they're for taste not visual effect.
  4. Bake for about 45 to 50 minutes, tenting or covering the pan with foil halfway through baking if you judge the bars to be browning a bit fast on top (I cover with foil halfway through because my oven browns things too fast on the surface before the interior cooks through). Bake until top is set and golden, the center is not jiggly, and edges have pulled away slightly from sides of the pan. A toothpick inserted in the center will likely not come out completely clean because bars are dense and gooey, both from the bananas and jelly, which may prevent a clean toothpick test. The bars are meant to be gooey and based on moisture content in bananas, yogurt used, oven variance, and personal preference, cooking times could vary from about 40 to 60 minutes. Allow bars to cool in pan for at least 1 hour before slicing and serving. While cake cools, make the glaze.
  5. For the Vanilla Glaze, optional - The bars don't 'need' a glaze as they're moist and sweet on their own, but I prefer it. Melt butter in a small microwave-safe bowl, about 1 minute on high power. Slowly add the confectioners’ sugar, vanilla, and whisk to combine. Add sugar as needed until desired glaze consistency is reached. Drizzle glaze over the top of bars before slicing and serving; or slice and glaze each piece individually. Unglazed bars can be stored in an airtight container at room temperature for up to 5 days; or store glazed bars in the refrigerator for up to 1 week, or in the freezer for up to 3 months.

  6. Oh goodness Averie, you’ve hit the nail on the head with these. I completely adore banana bread – in any form. These remind me SO much of your banana bread brownies – all that gorgeous glaze on top. “These bars are part jelly danish crossed with ultra moist banana bread.” – Ok, you’ve combined TWO of my very favorite breakfast foods and PEACH jelly is, and I’m not exaggerating here, my FAVORITE jam. Give me a fat slice of rye bread, a pat of butter, and peach jelly and I’m set for life. Coffee too. The ease of this recipe, the aded cornstarch (nice!) and pudding packet – incredible, I can only imagine how very soft & moist each bite is. I adore the photos – a warm “mood” over them all. I know you’re not a fan, but we are our own biggest critiques. Trust me, the pics are good. :)

    • I know you love peach jam and jelly! For some reason I think I read that somewhere in one of your posts – I knew that though. Maybe from your mango granola post or peach muffins post? Feels like ages ago that I’m recalling that little factoid from. Thanks for the compliments on my pics. Boy oh boy, things were hot and oh so gooey and melty. Tastes phenomenal, just not the easiest to shoot :)

  7. I’m totally missing summer fruit lately…especially peaches! These bars are such a fun way to revive the flavor. :)

  8. I looooove peach jelly and have been using it in all kinds of ways lately – my favorite so far has been using with for a sweet-spicy bbq chicken- but never thought about the combo with bananas! Sounds divine.

    And, oh my goodness, those brownies. They look TO. DIE. FOR.

  9. Oh my! These bars look so gooey and delicious! I love jam-filled baked goods!

  10. You and I must seriously live on the same wavelength. Yesterday I was searching the produce section for peaching thinking, “I need to bake something with peaches!!”

    • Can I just say that I am in love with your last post. I kid you not, cinnamon, bread, yeast, espresso, chocolate – they are all things I did individual posts on (many times, some of them) in just the past few months. Seriously we ARE on the same wavelength, hugely!

  11. Omg. The possibilities are endless in this yummy bar! I’m thinking cherry jam with cherry yogurt b/c I sooo miss eating the bing cherries! Strawberries also sounds very yummy too! I was way to curious today so I looked at your post before my email came!

  12. I can’t stop staring at that shiny top. It looks so sticky and delicious…I think I can almost taste it.

  13. Those look so soft and moist. I love banana breads. I really only have one recipe using bananas though.

  14. I love banana bread and these look especially yummy! But where’s the beach? I’ve been looking forward to some Aruba pics since you landed, LOL. Hope you and the family are having a wonderfully relaxing time :)

  15. I love reading your recipe ingredients because they are so creative. You obviously know what you’re doing when it comes to baking because you add your own little tweaks here and there to make your sweets pop with flavor.

  16. These look rich, moist, and absolutely lovely. The drizzle of icing on top makes these look decadent and delicate – well done!

  17. I love peach jelly too. This bars are like a little slice of heaven!

  18. Those strawberry jelly roles look divine! I bet if I made them I would eat the whole batch in one day x)

  19. I love how you roll with these baking fusion-like dishes. Baking fusion is now a thing and you are the pioneeress of it! Seriously, it just makes SENSE: banana bread is DELISH and jelly-filled donuts are the BOMB, why not combine them, right? Right. 100% right. I LOVE this!!

    • Well there’s only so many ways one can make banana bread and blog about it. If it was just us, I’d probably make…another loaf of plain banana bread. But that gets…boring. So…blogging forces me to step up my game and think creatively. And let’s face it, jelly goes with everything :)

  20. Another great spin on banana bread! Any of the jelly/jam suggestions sound good…and I bet these hit the spot in Aruba. I loved the butterscotch-caramel bars! Browned butter and dark brown sugar definitely make a good pairing in the base. I usually only have light brown sugar, but I like the dark and might see what else it tastes good in. Hope you are enjoying your time on the island!

    • They totally hit the spot and so glad you loved the butterscotch-caramel bars! I think dark brown sugar is a great touch for winter/fall heartier flavors and baking. Like any sort of molasses or ginger anything, from breads to cakes, it’s a nice touch!

  21. Oh Man!!! Just when I thought I had finished all of my Holiday baking. Now I will definitely have to add these to the cookie collection. Thanks for sharing Averie.

  22. How do you come up with all these recipe ideas girl!? You have something new every day!

  23. Okay seriously, how do you come up with some of your recipes? Amazing! You are so creative!! These look/sound incredible!

  24. Banana bread in a bar form?? Nice idea. Might do something like this this weekend!
