These Cinnamon Roll Bliss Bars have taken over my kitchen lately—and for a good reason. I wanted the cozy flavor of a cinnamon roll but in a form that’s easier to slice, store, and (honestly) sneak bites from the fridge. The first time I made these, I knew I struck gold. They’re rich, creamy, and layered with cinnamon sugar swirls that melt into the soft custard-like filling. And the base? Buttery, crumbly, and just the right amount of crunch to balance it all.

What I really love is how they manage to hit that nostalgic cinnamon roll flavor without needing to knead dough or wait for proofing. It’s a quick mix, pour, bake, and chill kind of dessert. Plus, they look beautiful—those swirled cinnamon ribbons are show-stopping. Whether you’re hosting brunch, need a cozy fall dessert, or want to impress at a potluck, these bars are always a hit.

What Kind of Cinnamon Should I Use for Cinnamon Roll Bliss Bars?

I always say: don’t underestimate the cinnamon! For these bars, the cinnamon is the heart of the flavor. I recommend using high-quality ground cinnamon—Ceylon if you want something more delicate and sweet, or Saigon cinnamon for a bold, spicy punch. Saigon tends to be my go-to for that unmistakable cinnamon roll vibe. Whichever type you choose, make sure it’s fresh. Stale cinnamon just won’t deliver the same magic in those gorgeous swirls.

Options for Substitutions

Whether you’re working with pantry limitations or just want to make these bars your own, here are some easy swaps you can try:

Dairy-Free: Use coconut milk or almond milk instead of whole milk. Full-fat canned coconut milk gives a luscious texture.
Gluten-Free: Swap the crust with gluten-free graham crackers or crushed gluten-free cookies.
Vegan: Use plant-based butter and milk alternatives, and replace eggs with a cornstarch slurry or flax eggs (though the texture might be slightly less creamy).
Low-Sugar: Substitute coconut sugar or a monk fruit blend for the sugar layers—just know the swirls might not be as vibrant.
Spice It Up: Add a pinch of nutmeg or cardamom to the cinnamon sugar mix for depth.
Crust Variety: Try gingersnap crumbs or crushed vanilla wafers for a twist on the base flavor.

Don’t be afraid to play with the recipe—these bars are surprisingly forgiving.

Ingredients for These Cinnamon Roll Bliss Bars

Each ingredient here plays a special role in bringing out the cinnamon roll magic in bar form. Here’s what you’ll need and why it matters:

Crushed Graham Crackers or Digestive Biscuits – These form the buttery crust that holds everything together and adds that necessary crunch.
Melted Butter – Mixed with the crumbs, it binds the base and adds rich flavor.
Granulated Sugar – Sweetens both the custard and the cinnamon swirl layers for balanced sweetness.
Ground Cinnamon – The star of the show, creating that warm, nostalgic cinnamon roll flavor.
All-Purpose Flour – Helps thicken the custard and provides structure.
Whole Milk – Creates a creamy, smooth custard base.
Sweetened Condensed Milk – Adds richness and sweetness, giving the filling its luxurious texture.
Cornstarch – Ensures a silky, firm custard layer that sets beautifully.
Vanilla Extract – Brings warmth and depth to the custard, tying all the flavors together.
Egg Yolks – Add richness and help thicken the filling as it bakes.

These ingredients come together to create bars that are luscious, layered, and bursting with cinnamon roll goodness.

Step 1: Prepare the Crust

Start by preheating your oven to 350°F (175°C). In a bowl, mix crushed graham crackers with melted butter and a tablespoon of sugar. Stir until the mixture resembles wet sand. Press it firmly into the bottom of a parchment-lined 8×8-inch baking pan. Bake for 8–10 minutes until lightly golden, then set aside to cool.

Step 2: Mix the Cinnamon Swirl

In a small bowl, combine granulated sugar with ground cinnamon. Set this aside—this will be layered throughout the custard to create those beautiful swirls and that signature cinnamon roll taste.

Step 3: Make the Custard Filling

In a saucepan over medium heat, whisk together whole milk, sweetened condensed milk, and vanilla extract. In a separate bowl, whisk egg yolks with flour and cornstarch until smooth, then slowly pour in some of the hot milk mixture to temper the eggs. Once tempered, pour the egg mixture into the saucepan and cook, whisking constantly, until thickened into a smooth custard.

Step 4: Layer and Swirl

Pour a thin layer of custard over the cooled crust, then sprinkle generously with the cinnamon sugar mixture. Repeat the process—custard, cinnamon sugar, custard—ending with a final dusting of cinnamon sugar on top. Use a toothpick or skewer to gently swirl the top layer for that cinnamon roll look.

Step 5: Bake and Chill

Bake the assembled bars at 325°F (160°C) for 20–25 minutes or until the edges are set and the center is just slightly jiggly. Let cool at room temperature, then refrigerate for at least 4 hours (overnight is even better) before slicing.

How Long to Cook the Cinnamon Roll Bliss Bars

The total cooking time is relatively short—about 20 to 25 minutes in the oven at 325°F (160°C). You’ll know they’re ready when the edges are set and the center has just a slight wobble, kind of like cheesecake. But the key is in the chill: these bars must rest in the fridge for at least 4 hours, preferably overnight, to fully set and develop that rich, creamy texture.

Tips for Perfect Cinnamon Roll Bliss Bars

Use Room Temperature Ingredients: This helps everything mix more smoothly, especially when tempering the eggs into the custard base.
Don’t Overbake: The custard should still jiggle slightly in the middle when it comes out of the oven—it’ll firm up as it cools.
Line Your Pan with Parchment Paper: It makes lifting and slicing the bars way easier once they’re chilled.
Chill Thoroughly: These bars taste best cold and need time to fully set, so don’t rush the chilling process.
Swirl Gently: Use a toothpick to swirl just the top layer for that classic cinnamon roll spiral—don’t mix too deep or you’ll lose the layers.
Use Fresh Cinnamon: A fresh, good-quality cinnamon makes a huge difference in flavor and aroma.
Slice with a Hot Knife: Run your knife under hot water and wipe clean between cuts for sharp, clean squares.
Double the Batch: These disappear fast. If you’re serving a crowd, go ahead and make a second pan!

Watch Out for These Mistakes While Cooking

Even though these Cinnamon Roll Bliss Bars are pretty straightforward, there are a few common pitfalls that can throw off the texture or flavor:

Skipping the Chill Time: The bars won’t set properly without a full chill, and cutting them too soon will leave you with a gooey mess.
Overheating the Custard: If you let it boil, the custard can curdle. Keep the heat medium and stir constantly for a silky texture.
Pouring Hot Custard Over the Crust: Let it cool just a bit before layering to avoid a soggy crust.
Uneven Swirling: Stirring too deep can mix the layers instead of creating that signature swirl. Keep it light and surface-level.
Using Cold Eggs: This can cause the custard to seize when combined with the warm milk. Let them come to room temperature first.
Not Weighing the Crust Down When Baking: If you’re not pressing the crust firmly or baking it long enough, it’ll crumble.
Underbaking: Don’t pull the bars out too early. The edges should look set, even if the center is slightly wobbly.
Rushing the Tempering: Pouring hot milk into eggs too quickly can scramble them. Go slow and whisk constantly.

What to Serve With Cinnamon Roll Bliss Bars?

1. Hot Coffee or Espresso

Storage Instructions

Once your Cinnamon Roll Bliss Bars have fully chilled and been sliced, store them in an airtight container in the refrigerator. They’ll stay fresh for up to 5 days, though chances are they won’t last that long! If stacking, place a piece of parchment paper between layers to prevent sticking.

You can also freeze them—wrap individual bars in plastic wrap and then place them in a freezer-safe bag or container. They’ll keep for up to 2 months. Thaw overnight in the fridge for the best texture.
