Ingredients for bacon butterscotch cake

Crispy bacon meets rich butterscotch in this decadent cake—moist layers and crunchy topping guaranteed.

The bacon is non-negotiable here—thick-cut, cooked until crispy gives that perfect smoky crunch. Costco or Trader Joe's usually carry the best quality for this purpose. Chop it into small pieces before baking so every bite has that salty punch. For the butterscotch chips, Ghirardelli or Guittard brands melt beautifully without burning. If you can't find butterscotch chips, use caramel chips at a pinch, though the flavor will be slightly different. The butterscotch sauce? Homemade is ideal—simmer equal parts brown sugar and cream until thickened—but a quality jarred sauce like Log Cabin works in a bind.

No butterscotch chips? Substitute with caramel chips or even chopped toffee, though the flavor won't be identical. Running low on powdered sugar for the glaze? Confectioners' sugar works the same. The heavy whipping cream in the glaze is crucial—full-fat only—for that perfect drizzle consistency. If you're feeling adventurous, swap half the butterscotch sauce for bourbon caramel in the batter. The eggs must be room temperature for a smoother batter, so take them out 30 minutes before mixing. For the butter, room temperature is key—soft but not melted. If it's too cold, the cake will be dense.

Store the cake in an airtight container at room temperature for up to 3 days, though it's best enjoyed fresh. The glaze can be made ahead and reheated gently if it thickens. For longer storage, wrap tightly in plastic and refrigerate for up to 5 days. The bacon crumbles stay crispy for about 2 days if stored separately. If you're making this for a crowd, double the batter and bake in a second pan—the secret to success. Serve warm with a scoop of vanilla ice cream for the ultimate indulgence.

Step-by-step instructions for bacon butterscotch cake

Here's how to create layers of rich butterscotch cake with smoky bacon crunch—every bite delivers perfect texture and flavor.

Line a baking sheet with parchment paper and arrange the 12 oz bacon in a single layer. Cook over medium heat in a skillet until deep golden brown and crispy, about 15-20 minutes. Drain on paper towels to remove excess fat, then let cool for 5 minutes. Once cool enough to handle, roughly chop the bacon into ¼-inch pieces—you want a mix of crumbles and small chunks for texture.

Here's the thing—don't skip the cooling step. Warm bacon releases more fat when chopped, which can make your cake greasy. The crumbles should be crispy enough to add crunch to the cake layers, while the larger pieces will provide that signature bacon bite. Set the crumbled bacon aside for the crunchy topping.

In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. The mixture should nearly double in volume and become pale in color. This step is crucial for creating that tender, moist crumb—the air incorporated here prevents dense cake.

Next, add the 1.5 cups packed light brown sugar and mix for another 1-2 minutes until fully combined. The brown sugar adds moisture and depth of flavor that complements the butterscotch perfectly. If your butter isn't quite room temperature (it should be soft but not melted), let it sit at room temperature for another 10 minutes before starting this step.

Add the 4 whole large eggs, one at a time, mixing on low speed for 30 seconds after each addition. Scrape down the sides of the bowl to ensure all ingredients are incorporated. Then add the 1 tbsp vanilla extract and mix for 10 seconds until just combined. The eggs provide structure while the vanilla enhances the butterscotch flavor profile.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 1 tsp ground cinnamon, and 0.5 tsp salt. Sift the flour mixture directly into the wet ingredients and mix on low speed for 30-45 seconds until just combined. You'll see small streaks of flour remain—this is perfect. Overmixing develops gluten, which leads to tough cake. Stop mixing as soon as the flour disappears.

Using a silicone spatula, gently fold in the 1.5 cups butterscotch chips by hand. The chips should be evenly distributed throughout the batter but not completely dissolved—you want pockets of butterscotch flavor in every bite. Preheat your oven to 350°F while you prepare the cake pans.

Grease two 9-inch round cake pans with butter and line the bottoms with parchment paper. Divide the batter evenly between the pans, smoothing the tops with a spatula. The batter should fill each pan about ¾ full—it will rise as it bakes. Tap each pan gently on the counter to remove any air bubbles that might have formed during pouring.

Bake the cakes for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning. Let the cakes cool in their pans for 10 minutes, then transfer to a wire rack to cool completely. This cooling period is essential—it prevents the cake from becoming gummy when you try to frost it.

Once completely cooled, level the tops of the cakes if necessary using a serrated knife. For the crunchy topping, combine the 0.5 cup butterscotch sauce, 1 cup powdered sugar, and 0.25 cup heavy whipping cream in a small bowl and whisk until smooth. Spread this mixture evenly over the top cake layer, then sprinkle the crumbled bacon evenly across the surface. Place the second cake layer on top and press gently to create a sealed cake.

Flavor customization for this recipe

Sweet-Smoky Balance

Adjust the bacon-to-butterscotch ratio to suit your taste. For a bolder smoky flavor, increase the bacon crumbles by ¼ cup and reduce butterscotch chips by the same amount. For a sweeter profile, swap ½ cup of the brown sugar for extra butterscotch chips and add 1 tsp vanilla bean paste to deepen the caramel notes. 🌶️

Boozy Twist

Infuse the batter with bourbon or butterscotch schnapps for an adult-friendly upgrade. Replace 2 tbsp of the butterscotch sauce with 2 tbsp bourbon (like Maker’s Mark) or 1 tbsp butterscotch liqueur (like Torani). Simmer the bourbon with ½ cup cream for 3 minutes to reduce the alcohol content before mixing into the batter. This adds warmth and complexity.
