irresistible peanut butter and jam bars (gluten-free & vegan)
if you’re craving a dessert that hits all the right notes—sweet, nutty, fruity, and perfectly crumbly—these peanut butter and jam bars are exactly what you need!
they’re gluten-free, vegan, and absolutely delicious.
the combination of a soft, chewy base with a layer of homemade blueberry chia jam and a crunchy crumble topping makes these bars a treat you won’t be able to resist.

taste and texture
these bars are a fun mix of textures and flavors.
the base is rich and buttery, thanks to the combination of almond flour and peanut butter, while the blueberry chia jam adds a bright, tangy sweetness.
the crumble topping provides the perfect contrast with its crispiness, making each bite a little piece of bliss in taste and texture.
how to make these peanut butter and jam bars
making these bars is simpler than you might think.
it starts with a peanut butter and almond flour base that’s easy to mix up and press into a 9×5-inch loaf pan.
next, you whip up a quick blueberry chia jam by cooking frozen blueberries with chia seeds, water, maple syrup, and a touch of arrowroot powder to thicken it up.
once the jam is spread over the base, a crumbly topping made from almond flour, oat flour, oats, and coconut sugar is sprinkled on top.
after a short bake in the oven, you’ll have a batch of delicious peanut butter and jam bars ready to enjoy.

key ingredient: edward & sons, let’s do organic, organic cornstarch
one of the secrets to these bars’ perfect texture is the use of edward & sons, let’s do organic, organic cornstarch.
this cornstarch is a staple in my baking because it adds a lightness and tenderness to the dough that’s hard to achieve with other ingredients.
it also plays a crucial role in thickening the blueberry chia jam, giving it just the right consistency to hold up between the layers.
if you’re looking for a high-quality cornstarch for your baking, i highly recommend giving this one a try. it’s organic, reliable, and perfect for gluten-free recipes.
jam fruit substitutions
while the blueberry chia jam is a classic choice, you can easily swap in other fruits to suit your taste or what you have on hand.
strawberries, raspberries, or blackberries would all work beautifully in this recipe.
you could even mix a few different berries together for a mixed berry jam.
if you prefer a less tangy flavor, peaches or apricots would make a deliciously sweet alternative. just follow the same process for making the jam, adjusting the sweetness to your liking.

nut butter substitutions
peanut butter is a classic choice for these bars, but you can easily switch it out for other nut or seed butters if you prefer.
almond butter would add a mild, creamy flavor, while cashew butter would give the bars a slightly richer, buttery taste.
for a nut-free option (although the base has almond flour), sunflower seed butter or tahini would work well, adding their own unique flavors to the mix.
how to serve
these peanut butter and jam bars are perfect for any occasion.
they make a great afternoon snack with a cup of tea or coffee, or you can serve them as a dessert at a casual gathering.
for an extra indulgent treat, try warming a bar slightly and serving it with a scoop of dairy-free vanilla ice cream or a dollop of coconut whipped cream.
the warm, melty jam paired with the cold, creamy ice cream is simply irresistible.
storage tips
to keep your peanut butter and jam bars fresh, store them in an airtight container at room temperature for up to 3 days.
if you want them to last longer, you can refrigerate them for up to a week.
these bars also freeze well, so you can make a batch ahead of time and freeze individual squares for a quick treat whenever the craving strikes.
just let them thaw at room temperature for a bit before enjoying.
these peanut butter and jam bars are a must-try if you love the combination of nut butter and fruit.
they’re easy to make, incredibly satisfying, and perfect for both casual snacking and more special occasions.
give them a try, and they just might become your new favorite treat!

- for the base:
preheat your oven to 350°f (175°c) and line a 9×5-inch loaf pan with parchment paper. - in a large mixing bowl, whisk together the almond flour, oat flour, cornstarch, baking powder, and sea salt until well combined.
- add the peanut butter, maple syrup, melted coconut oil, and vanilla extract to the dry ingredients. mix until a dough forms. press the dough evenly into the prepared pan to form the base layer.

bake the bars in the preheated oven for 25-28 minutes, or until the top is golden brown and the edges are set.
remove from the oven and let the bars cool completely in the pan before cutting into squares. this is important to ensure the jam sets. you can even place in the fridge or freezer 30 min or so. enjoy!!
