This Carmelitas recipe has been a kitchen staple since I first made it for a holiday cookie swap and discovered how quickly a tray disappears at family gatherings. I stumbled on this combination when I wanted something simpler than candy but richer than a cookie: a crisp oat base, a melty chocolate middle, and a creamy caramel ribbon on top. The result is a bar that balances textures—crunch from the oats, tender chewiness from the caramel, and a soft chocolate buffer in between—so every bite feels like a little celebration.

I remember unwrapping the individually wrapped caramels at midnight while the first half of the base baked, the house filled with a buttery, toasty aroma. My partner declared them addictive, and my neighbor asked for the recipe on the spot. What makes these bars special is that they borrow pantry staples—old fashioned oats and brown sugar—but present them in layers that look and taste luxurious. They’re forgiving, travel well, and make an excellent gift when cut into neat squares and tied with twine.

Ingredients

• All-purpose flour: Use 1 1/2 cups of an unbleached brand like King Arthur for consistent structure; it helps the base hold together while still tender.
• Old fashioned oats: 1 1/2 cups of rolled oats (not quick oats) give the pleasant chew and toasted texture; Bob's Red Mill works great.
• Salted butter: 1 cup melted (2 sticks). Butter adds richness and helps the oat mixture crisp; use real butter rather than margarine for flavor.
• Light brown sugar: 3/4 cup packed. The molasses in brown sugar deepens flavor and keeps the base slightly sticky after baking.
• Pure vanilla extract: 2 teaspoons for aromatic depth; avoid imitation if you can.
• Baking soda: 1 teaspoon to give a little lift so the bottom layer isn't overly dense.
• Kosher salt: 1/2 teaspoon to balance the sweetness; use Diamond Crystal or Morton adjusted to taste.
• Milk chocolate chips: 1 1/2 cups. Choose a good melting chip like Ghirardelli for smoothness between layers.
• Caramels: 11 ounces individually wrapped caramels (store-brand or Kraft are fine); they melt smoothly for the caramel ribbon.
• Heavy cream: 1/2 cup to thin and enrich the caramel into a sauce that pours evenly.

Instructions

Prepare the pan and oven: Preheat the oven to 350 degrees Fahrenheit. Line a 9 by 9 inch baking dish with parchment paper leaving a 1 to 2 inch overhang on two sides for easy lifting. Lightly spray the parchment with nonstick spray so the bars release cleanly after chilling. Make the oat cookie mixture: In a large bowl combine 1 1/2 cups all-purpose flour, 1 1/2 cups old fashioned oats, 1 cup melted salted butter, 3/4 cup packed light brown sugar, 2 teaspoons pure vanilla extract, 1 teaspoon baking soda and 1/2 teaspoon kosher salt. Stir with a spatula until just combined; the mixture should be crumbly but pressable. If the butter has cooled and the mix seems dry, add a teaspoon of warm water. Form and par-bake the base: Press half of the oat mixture firmly into the bottom of the prepared pan to form an even layer about one-third inch thick. Use the bottom of a measuring cup to compress the dough evenly; this ensures a compact, golden base. Bake for about 10 minutes, or until edges are just turning golden. This step sets the base so it supports the chocolate and caramel without sinking. Prepare the caramel: While the base bakes, unwrap 11 ounces of individually wrapped caramels. In a small heavy-bottomed saucepan over medium-low heat, combine the caramels and 1/2 cup heavy cream. Stir constantly with a silicone spatula until the caramels fully melt and the mixture is smooth, about 4 to 6 minutes. If using a microwave, combine in a microwave-safe bowl and heat in 30 second bursts, stirring between, until smooth. Keep the sauce warm but not boiling. Layer the chocolate: Remove the par-baked base from the oven and immediately sprinkle 1 1/2 cups milk chocolate chips over the warm crust so the chips soften but do not completely melt into a single mass. The warmth helps them spread slightly and creates a glossy bridge between the base and caramel. Pour the caramel: When the caramel is silky smooth, pour it evenly over the chocolate chips. Spread gently with an offset spatula if needed to reach corners. The heat from the caramel will partially melt the chips and form an integrated middle layer. Top with remaining oat mixture and bake: Scatter the remaining oat mixture evenly over the caramel layer; press gently in a few places but do not compact tightly—small gaps are fine and will seal during baking. Bake for 18 to 22 minutes at 350 degrees Fahrenheit, or until the top is golden and firm to the touch. Rotate the pan once halfway through for even browning. Chill and slice: Allow the bars to cool on a rack for 10 minutes, then refrigerate for 1 1/2 to 2 hours to fully set the caramel. Use the parchment overhang to lift the slab from the pan, place on a cutting board, and slice into 16 equal squares. For clean cuts, chill thoroughly and use a sharp knife warmed under hot water and dried between cuts.

Storage Tips

To keep the bars at peak quality, cool them completely before covering. For short term, place in a single layer in an airtight container lined with parchment and store in the refrigerator for up to seven days. For longer storage, flash freeze on a tray for an hour, then wrap tightly in plastic wrap and store in a freezer-safe bag for up to three months. When reheating, microwave a single bar for 8 to 12 seconds to soften the caramel, or place frozen bars in the refrigerator overnight to thaw slowly and preserve texture.

Ingredient Substitutions

If you need gluten-free options, swap the all-purpose flour for a 1-to-1 gluten-free flour blend and use certified gluten-free oats; results are slightly crumblier but still delicious. For a dairy-free version, use dairy-free butter and coconut cream in place of heavy cream, and choose dairy-free chocolate chips—note the flavor shifts with coconut notes. To intensify flavor, replace half the milk chocolate chips with dark 60 percent chocolate or add 1/2 cup toasted chopped pecans into the oat mixture for crunch.

Serving Suggestions

Serve the squares slightly chilled for neat bites or warm for melty caramel appeal. Pair with a robust coffee or a glass of cold milk. For a festive presentation, dust with a light sprinkle of flaky sea salt or drizzle with melted dark chocolate. These also make a lovely addition to dessert boards alongside shortbread and fruit, and are easy to portion for party guests—stack them in a festive box with parchment for homemade gifts.

Cultural Background

The layered oat bar family traces back to simple European and American baking traditions where oats and butter form the basis for hearty biscuits and bars. Carmelitas are an American adaptation that highlights the mid-20th century popularity of individually wrapped caramels and convenience ingredients. They combine the rustic textures of oat cookies with confection-style caramel and chocolate layers to create a hybrid that’s both nostalgic and contemporary.

Seasonal Adaptations

Adapt these bars to the season by swapping the chocolate: use white chocolate and crushed peppermint in winter, or add dried cherries and orange zest in winter for brightness. In autumn, stir in 1 teaspoon ground cinnamon and 1/4 teaspoon nutmeg to the oat base and top with toasted walnuts. For summer gatherings, serve chilled with a scoop of vanilla ice cream so each bar becomes a mini sundae.

Meal Prep Tips

For efficient meal prep, double the recipe and bake in a quarter sheet pan, extending bake time by a few minutes and checking for firm edges. Cut into portions and freeze individually wrapped for grab-and-go treats. Label containers with date and flavor variations. Keep a small jar of caramel sauce in the fridge for up to two weeks to refresh slightly dried bars by brushing a thin layer over the surface and chilling briefly before serving.

These Carmelitas are proof that simple pantry staples can produce something decadent and memorable. Whether you’re packing them for a picnic, gifting them during the holidays, or keeping a tin in the fridge for yourself, they hold a special place on my baking list for reliably impressive results.
