Ingredients for bacon butterscotch cake
Eight layers of decadence: crispy bacon, moist cake, and gooey butterscotch glaze await.
| Ingredient | Amount | Notes |
|---|---|---|
| Thick-Cut Bacon 🥓 | 12 oz | Smoked, thick-cut for crispiness |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for cake layers |
| Granulated Sugar 🍚 | 2 ½ cups | For cake layers and glaze |
| Light Brown Sugar 🍚 | 1 ½ cups | Packed for butterscotch filling |
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted, for sturdy cake layers |
| Buttermilk 🥛 | 2 cups | Room temperature for tenderness |
| Large Eggs 🥚 | 4 whole | Room temperature, separated |
| Baking Powder 🧂 | 2 tbsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Kosher or fine sea salt |
| Vanilla Extract 🍯 | 2 tsp | Pure, high-quality extract |
| Butterscotch Chips 🍬 | 2 cups | For filling texture |

The bacon is non-negotiable—thick-cut smoked bacon from Costco or your local butcher delivers that perfect crunch. Look for slices with good marbling; they caramelize better. I like to buy mine in bulk because it keeps for months in the freezer. The butterscotch chips should be the real deal, not those pre-made filling packets—they melt differently. Ghirardelli or Guittard brands are my go-to for that authentic caramel flavor. For the cake layers, the flour needs to be sifted—King Arthur or Gold Medal brands work best for that sturdy yet tender texture we're after.
No thick-cut bacon? Regular bacon cooked until extra crispy works in a pinch, but it won't have that same satisfying crunch. Running out of butterscotch chips? Chopped butterscotch candy bars (like Heath or Butterfinger) substitute perfectly—they just melt faster. The buttermilk is crucial for that moist crumb; if you don't have any, milk plus a splash of vinegar does the trick. For the glaze, powdered sugar can be swapped for superfine sugar if you're in a hurry, but sifting is key to avoid lumps. The corn syrup adds that glossy finish—Karo brand is what I always reach for when I need that professional look.
Bacon keeps best in the fridge for 5 days if unopened, but once cooked, store it in an airtight container for 3-4 days—it's worth freezing extra for future projects. The cake layers can be baked a day ahead and stored at room temperature, covered tightly. The glaze ingredients should be mixed just before pouring to maintain that glossy texture. This cake reheats beautifully—10 seconds in the microwave brings back that gooey glaze perfection. For special occasions, I like to make two batches and freeze one—3 months in the freezer with parchment between layers keeps it fresh.

Step-by-step instructions for bacon butterscotch cake
Here's how to bake this decadent cake with perfectly crisp bacon and gooey caramelized layers.
Cook and Crumble the Bacon
Line a baking sheet with parchment paper and arrange the 12 oz thick-cut bacon in a single layer. Cook in a cold skillet over medium heat for 18-22 minutes, flipping once, until the bacon reaches 195°F internally and is deep golden brown with crisp edges. The reason for this low-and-slow approach is to render maximum fat while keeping the bacon tender enough to crumble.
Transfer the cooked bacon to a paper towel-lined plate to drain for 5 minutes, then carefully crumble it into ¼-inch pieces using two forks. Reserve ¼ cup of the rendered bacon fat in a small bowl—this golden liquid is pure flavor that we'll use later. The remaining fat can be discarded, but don't waste the bacon itself; every crumb will contribute to that signature salty-sweet contrast.
Prepare the Cake Layers
Preheat your oven to 350°F and grease three 8-inch round cake pans with the reserved bacon fat, then line the bottoms with parchment circles. In a stand mixer fitted with the paddle attachment, cream together the 1.5 cups unsalted butter and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. This step is crucial—it incorporates air that will make your cake layers tender rather than dense.
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then whisk together the 2 cups buttermilk, 2 tsp vanilla extract, and 0.5 tsp salt in a separate bowl. Gradually add the buttermilk mixture to the butter mixture, alternating with the 3.5 cups all-purpose flour and 2 tbsp baking powder, beginning and ending with the flour. Mix just until combined—overmixing develops gluten and makes the cake tough.
Bake and Assemble the Layers
Divide the batter evenly among the prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in their pans for 10 minutes, then transfer to a wire rack to cool completely. While they cool, make the butterscotch filling by melting the 1.5 cups light brown sugar and 2 cups butterscotch chips in a microwave-safe bowl in 30-second intervals, stirring between each, until completely melted and smooth.
Once the cakes are completely cool, level the tops if needed. Place one layer on a plate and spread ½ of the butterscotch filling evenly over the top. Add the crumbled bacon evenly, then top with the second cake layer. Repeat with the remaining filling and bacon, then top with the final cake layer. This assembly creates the signature layers that make this cake irresistible—each bite delivers cake, bacon, and butterscotch in perfect harmony.
Make the Caramelized Glaze
In a small saucepan, combine the 1 cup heavy cream, 2 cups powdered sugar, 0.25 cup corn syrup, and the reserved ¼ cup bacon fat. Cook over medium heat, stirring constantly, until the mixture reaches 235°F on a candy thermometer and begins to thicken slightly. This high temperature creates that signature glossy, caramelized finish that makes the cake look (and taste) like it came from a bakery.
Immediately pour the glaze over the assembled cake and let it set for 15 minutes at room temperature. The glaze will harden slightly as it cools, creating that beautiful crackly top. For best results, refrigerate the cake for at least 2 hours before serving—this allows the flavors to meld and the glaze to set properly. The contrast of the warm, gooey butterscotch filling with the crisp bacon and tender cake layers makes every bite unforgettable.
Pro Tips For Making Bacon Butterscotch Cake
- CRISP THE BACON FIRST: Cook the thick-cut bacon until it’s deep golden and nearly crisp—18-20 minutes at medium-low heat—before chopping. I used to rush this and ended up with greasy, limp bacon bits that turned the cake soggy. Patience here makes the flavor pop without weighing down the batter.
- WHISK BUTTER AND SUGARS: Melt the unsalted butter first, then whisk it with the granulated and brown sugars until fully combined and slightly thickened. This step prevents grainy pockets in the cake and ensures the butterscotch flavor melts evenly into the batter. (Yes, even if you’re impatient like me.)
- SIFT THE FLOUR DRY: Sift the all-purpose flour directly into the batter in two additions, letting it settle between each. I learned this the hard way—packing flour into the measuring cup compresses it, and the cake turns dense. A quick shake of the sifter fixes that every time.
- BAKE UNTIL 205°F: Pull the cake out when the center hits 205°F (not 212°F)—the residual heat will carry it to perfect doneness without overbrowning. I skipped this once and got a dry, cracked top. A thermometer is worth the $10; trust the number, not just the look.
Pro cooking tips for this recipe
Bacon Caramelization
Caramelizing the bacon is where the magic happens—don't rush this step! Cook the 12 oz thick-cut bacon in a cold skillet over medium heat for 18-22 minutes, flipping once. The key is patience: cooking it slowly renders the fat perfectly while keeping the bacon tender enough to crumble. I use a meat thermometer to check the internal temp at 195°F—this ensures it's cooked through but still pliable. 🔥
After cooking, drain the bacon on paper towels for 5 minutes to remove excess grease, then crumble it into ¼-inch pieces using two forks. Reserve ¼ cup of that golden bacon fat—it's liquid flavor gold! The remaining fat can be saved for future cooking, but don't skimp on the crumbles. Every bite needs that salty crunch to contrast the sweet butterscotch.
Cake Layer Mastery
For tender yet sturdy cake layers, cream the 1.5 cups unsalted butter and 2.5 cups granulated sugar together for 3-4 minutes until light and fluffy. This step is non-negotiable—it incorporates air that prevents dense cake. I like to use a stand mixer with paddle attachment for consistent results. Add the 4 eggs one at a time, mixing well after each addition to maintain that airy texture. 🥚
When mixing the dry ingredients, sift the 3.5 cups all-purpose flour and 2 tbsp baking powder together before adding to avoid lumps. Alternate between the buttermilk mixture and dry ingredients, beginning and ending with the flour. Mix just until combined—overmixing develops gluten and makes the cake tough. The goal is a smooth, pourable batter that holds its shape when baked.
Filling Technique
For the butterscotch filling, melt the 1.5 cups light brown sugar and 2 cups butterscotch chips in 30-second intervals in the microwave, stirring between each. This gradual approach prevents burning while ensuring a smooth, melted texture. The filling should be thick but pourable—if it's too runny, chill it for 10 minutes to thicken slightly. 🍬
When assembling, spread the filling evenly between layers—about ⅓ cup per layer. The bacon goes next, sprinkled generously so each bite has that salty crunch. Press down gently to help the layers adhere. The secret to perfect assembly is patience: let each layer cool completely before adding the next to prevent sogginess.
Glaze Perfection
The glaze is where the cake gets its showstopping finish. Combine the 1 cup heavy cream, 2 cups powdered sugar, 0.25 cup corn syrup, and reserved ¼ cup bacon fat in a saucepan. Heat over medium while stirring constantly until it reaches 235°F on a candy thermometer. This high temperature creates that glossy, crackly finish. 🌟
Work quickly when pouring the glaze—it thickens fast! Let it set for 15 minutes at room temperature before refrigerating for 2 hours. This chilling time is crucial for the glaze to set properly and for the flavors to meld. The result should be a cake with a beautiful crackly top and a gooey center that's impossible to resist.

Frequently asked questions
Can I substitute regular bacon for thick-cut bacon in this recipe?
You can use regular bacon, but the texture will be different. Thin bacon becomes crispier faster but loses its tender crumble. For best results, cook it until extra crispy and chop it finely. The flavor will still work, but you'll miss that perfect salty-sweet contrast from properly caramelized thick-cut bacon.
How do I make this cake ahead of time?
Bake the cake layers and assemble the cake (without glaze) up to 2 days ahead. Store them separately in airtight containers at room temperature. When ready to serve, add the glaze and let it set for 2 hours before slicing. The flavors actually improve overnight as the butterscotch filling melds with the cake layers.
What if my glaze turns out too runny?
If your glaze is too thin, simply return it to the saucepan and cook for an additional 1-2 minutes while stirring constantly. You can also add 1-2 tablespoons of powdered sugar at a time until it reaches the right consistency. The glaze should coat the back of a spoon but still be pourable. For a quick fix, chill the cake for 30 minutes before serving—cold temperatures help thicken the glaze.
Can I make this cake without butterscotch chips?
You can substitute with 2 cups chopped butterscotch candy bars (like Heath or Butterfinger) or make your own butterscotch sauce by combining 1.5 cups brown sugar, ½ cup heavy cream, and 1 tbsp butter, then simmering until thickened. The texture will be slightly different but still delicious. For extra richness, add 1 tsp vanilla extract to the filling.
How do I prevent the cake layers from getting soggy?
Sogginess happens when moisture isn't properly managed. Always let each cake layer cool completely before assembling, and make sure your butterscotch filling is thick but pourable. For extra insurance, brush each layer with a thin layer of simple syrup (equal parts sugar and water) before adding the filling—this creates a moisture barrier. Also, don't skip the chilling time before serving! The 2-hour refrigeration is crucial for that perfect texture.
