Cinnamon Apple Crisp Bars

These cinnamon apple crisp bars are my answer to cozy comfort on cool days. You get that warm, spiced apple filling and crunchy oat topping in a handy bar form—no bowl required. They make a nostalgic fall treat for family dessert or an anytime afternoon snack packed into a single bite.

I first made these bars on a chilly Sunday when I wanted apple crisp without the fuss. My kids always sneak extras into their backpacks—these do not last long in my house.

Ingredients

• Old fashioned rolled oats: Essential for hearty texture and a golden topping Look for fresh oats at the grocery store with no lingering stale smell
• All purpose flour: Helps hold the crust and topping together Opt for a name brand for dependable results
• Light brown sugar: Packed into the measuring cup for rich caramel notes Choose a fresh soft pack for best flavor
• Ground cinnamon: Warm aromatic spice that defines the recipe Use a fresh bottle for vibrant color and aroma
• Salt: Brings out all the sweet apple flavors I recommend fine sea salt for even distribution
• Unsalted butter: Melted for easy mixing and rich flavor European style butter gives an extra boost but any good quality works
• Large apples: Granny Smith or Honeycrisp for firm juicy texture Choose apples with tight skin and no bruises
• Granulated sugar: Lifts the natural sweetness of the apples Cane sugar gives a cleaner taste
• All purpose flour: Thickens the apple filling You only need a little but do not skip it
• Ground nutmeg: Gives the filling a gentle warmth Freshly grated nutmeg is especially fragrant if you have it
• Lemon juice: Brightens up the fruit flavor Use a firm fresh lemon and squeeze just before adding

Instructions

Prepare the Baking Pan:

Line your eight inch square pan with parchment paper making sure you have an overhang on all sides This makes it so much easier to lift the bars out after baking

Mix the Oat Crust and Topping:

In a large bowl combine oats flour brown sugar cinnamon and salt Stir everything together until it is combined well Then add melted butter and mix thoroughly until you have a crumbly texture with no dry spots

Set Aside Topping Reserve:

Scoop out one cup of the oat mixture and set it aside for the topping You will use this to finish the bars later

Press the Crust:

Take the remaining oat mixture and press it very firmly into the bottom of your lined pan Pack it down with your fingers or the back of a measuring cup until it is even and compact This keeps the bars from crumbling when you cut them

Prepare Apple Filling:

In a separate bowl toss your diced apples with sugar flour cinnamon nutmeg and lemon juice Stir until every piece is evenly coated and the mixture looks slightly glossy

Layer the Apples:

Spread the apple filling evenly over the crust layer using a spatula to smooth it out to the edges Make sure every spot is covered for even baking

Top with Crumble:

Sprinkle the reserved oat mixture evenly over the top of the apples Pat it down very gently with clean hands to help it stick together while baking

Bake the Bars:

Place the pan in your preheated oven and bake for about forty to forty five minutes The top should be golden brown and the apples should be bubbling around the edges The smell will fill your whole kitchen with cinnamon goodness

Cool and Slice:

Let the bars cool completely in the pan on a wire rack This helps everything set up neatly Use the parchment sling to lift out the bars and cut into even portions with a sharp knife

My favorite part is always the buttery oat crumb topping I once made these for our family picnic and my uncle declared them the best version of apple crisp he had eaten Years later the kids still ask for these when the leaves start to fall

Storage Tips

Let bars cool completely before storing Transfer to an airtight container with parchment between layers to keep them from sticking You can refrigerate for up to five days or freeze well wrapped for up to three months Warm briefly in the oven to refresh the texture

Ingredient Substitutions

Swap pears for apples if you have them around For a nutty crunch add coarsely chopped walnuts or pecans into the topping To make dairy free use a good quality plant based butter The filling can be sweetened with coconut sugar as an alternative as well

Serving Suggestions

Tempting served warm with a scoop of vanilla ice cream or a drizzle of salted caramel Take them along to a picnic or holiday gathering or pack into lunchboxes for a midday treat I have even turned leftovers into a breakfast parfait layered with Greek yogurt
