Step By Step Instructions- Butterscotch Cake Batter, Butterscotch Sauce, and Butterscotch Buttercream

Here is how to make and bake the butterscotch sauce, cake, drip, and frosting. You will need a stand mixer with a paddle attachment or a hand mixer.

STEP 1: Butterscotch sauce. In a medium saucepan over medium heat, heat the butter first. Then, add in the brown sugar, heavy cream, and salt. Mix using a whisk until combined.

Let it come to a boil and set a timer to cook for 5 minutes. During this time it is super important to not stir it at all. If you stir it even once, it will cause a grainy sauce. Then, take off the heat and add in the vanilla extract.

STEP 2: Mix the dry ingredients. In a medium bowl, mix the all-purpose flour, baking powder, baking soda, and salt.

STEP 3: Mix the wet ingredients. In a large bowl, beat the butter and brown sugar on high speed for 3 minutes. Then, add the vanilla and butterscotch sauce.

Next, add one egg at a time at medium speed.

STEP 4: Add the flour mixture and buttermilk. Alternate between these two on low speed. Then, pour batter into three 8-inch cake pans.

Bake for 20-24 minutes. Cool the cakes on a cooling rack completely.

If any butterscotch chunks remain, heat in the microwave for 10 seconds.

Important: Make sure the ganache is not hot or warm when using for the frosting or the drip. Also, make this right before making frosting and decorating the cake.

STEP 6: Butterscotch frosting. First, mix the butter on high speed for 4 minutes. This will help you have a fluffy frosting. Then, add the powdered sugar on low speed.

Next, add in the vanilla, salt, and butterscotch ganache. The frosting will be super fluffy.

Recipe Variation

  • Butterscotch chips: You can use the butterscotch ganache and use that instead of homemade butterscotch sauce.

Assembling The Cake Tips

  • Items that will be helpful in cake decoration: turntableicing offset spatulasstraight icing spatulacake scrappercake leveler (or a bread knife), and a cake carrier.
  • If you have any uneven cake layers, use a serrated knife or cake leveler to cut the top, so they are perfectly even.
  • First, spread 3/4 cup of frosting over the 1st cake layer. Use a piping bag to pipe the frosting around the edge of the cake. This helps to prevent the butterscotch sauce from oozing out.
  • Spread 1/2 cup of butterscotch sauce in the middle of the cake.
  • Repeat with the second layer. Place the last layer of cake with bottom of the cake facing up.
  • Important: Go quickly when filling the cake, and then place in the freezer for 10 minutes. Otherwise the sauce will spill out.
  • Frost the cake in a light layer of frosting. Place back in the freezer for 15 minutes to completely set. The freezer is your best friend, so the sauce won’t ooze out.
  • Frost the rest of the cake.
  • If the butterscotch ganache has cooled too much, heat back in the microwave for 10-15 seconds until pourable.
  • Pour the ganache on top of the cake, and let it pour down the sides of the cake. You can also place the ganache in a piping bag to pipe the drips down the sides of the cake as well.

FAQ

What happens if the sauce oozes out of the cake while frosting?

Apply frosting and freeze until the frosting is completely set. Then, you can frost the rest of the cake.

Can I make this into cupcakes?

Yes you can! It will make 24 cupcakes. Half the recipe for 12 cupcakes. Bake for 18-20 minutes.

What other cake pans can I use?

You can use 2 9-inch cake pans, or 4 6-inch cake pans, or a 9X13-inch cake pan (half the frosting recipe for this pan).

Can I make the cake part ahead of time?

YES! In fact that is exactly what I did for this cake. I made the cake ahead of time, once it cooled completely I wrapped it tightly in plastic wrap. Then, when it was time to decorate, pull it out at least 1 hour.

Special Tools

  • Cake pans: I use Wilton 8-inch cake pans.
  • Parchment paper circles: I used 8-inch parchment paper circles for the bottom of the pan. I love to use the premade circles, so I don’t have to cut it out of regular parchment paper.
  • Baking spray: I use the nonstick spray that has flour in it.
  • Offset spatula: I use this to easily spread the frosting or fillings.
  • Cake turntable: I use this nice Ateco cast iron turntable because it is high quality and it spins seamlessly. Some other turntables are a little jerky when they turn.
  • Cake scraper: I use a metal scraper to get smooth cakes.
  • Piping bags: I like these 18- inch piping bags since they hold more.
  • Piping tip: I love this Wilton 1M to pipe frosting.

Storing and Freezing

Store this butterscotch cake in an airtight container like a cake carrier. Store in the fridge up to 5 days.

The cake taste best at room temperature.

Freezing

The cake can be frozen in individual cake slices. Wrap the slices in plastic wrap and freeze up to 30 days. Thaw for 1 hour before eating.

  • Pour the cake batter evenly into each cake pan. Bake for 24-28 minutes. Bake until a toothpick inserted comes out clean.
  • Let the cakes sit in the hot pans for 10 minutes. Transfer the cakes onto a cooling rack. Cool completely.

Assembly

  • Use a serrated knife or a cake leveler to cut the domes off the cakes so they are even.

  • Spread a light layer of frosting over the cake and freeze for 15 minutes.
  • Frost the rest of the cake. I used a cake scrapper to decorate the cake as a semi-naked look. Freeze for 10 minutes.
  • Heat the ganache back in the microwave, so it is melty. Make sure it is room temperature before applying to the cake. If it is too hot, it will drip everywhere. Place the 1/3rd of the ganache into a piping bag, and pour the drip on the edge of the cake.
  • Pour the rest of the ganache on top of the cake.
