Why You’ll Love This Old Fashioned Banana Pudding Lava Cake

• Spectacular Lava Effect: Utilizing a standard bundt pan allows the gorgeous banana frosting to pool perfectly in the center, creating a stunning, melt-in-your-mouth lava river when cut.

• Deliciously Doctored Cake Base: Transforming a simple boxed white cake mix with real butter, rich milk, and instant banana pudding mix yields an exceptionally moist, bakery-quality crumb.

• Toasted Meringue Perfection: The homemade 7-minute frosting gets a quick kiss from a kitchen torch, providing a beautiful campfire-toasted finish that looks as amazing as it tastes.

Ingredients

For the Doctored Banana Cake:

• 1 box Duncan Hines White Cake Mix

• 1 box Sonic Banana Shake Instant Pudding Mix

• 1/2 cup real unsalted butter, melted (substituted for oil on the box)

• 1 cup whole or 2% milk (substituted for water on the box)

• 4 large eggs (adds 1 extra egg to what the box calls for)

• 1 teaspoon almond extract

• 1 teaspoon vanilla extract

• 1 fresh banana, sliced

• 1 to 1 1/2 cups butterscotch chips

For the Banana 7-Minute Frosting:

• 5 large egg whites

• 1/2 teaspoon cream of tartar

• 1 2/3 cups granulated sugar

• 1 teaspoon vanilla extract

• 1 1/2 to 2 fresh bananas, mashed into a smooth puree

• Extra butterscotch chips (optional, to fold in)

For the Finishing Glaze:

• 1 cup powdered sugar

• 2 tablespoons milk

• 1 teaspoon vanilla extract

• 1/2 teaspoon almond extract

Instructions

Step 1: Mix and Bake the Cake

• In a large bowl, combine the white cake mix, banana pudding mix, melted butter, milk, eggs, almond extract, and vanilla extract; blend thoroughly with a hand mixer.

• Lightly coat your fresh banana slices in flour to keep them from sinking, then gently fold them and the butterscotch chips into the cake batter.

• Pour into a greased bundt pan and bake according to the timing on the back of the cake mix box.

Step 2: Whip Up the 7-Minute Frosting

• Wipe down your metal mixing bowl and whisk with lemon juice to guarantee there is zero oily residue left behind.

• Hand-whisk the egg whites, cream of tartar, and granulated sugar together in the bowl for 3 minutes.

• Place the bowl over 1-2 inches of gently simmering water, whisking constantly for 2-3 minutes until the mixture safely reaches 160°F.

• Remove from the heat and whip on high with a hand mixer for 5-7 minutes until stiff peaks form, slowly streaming in your vanilla extract and gently folding in the mashed banana puree.

Step 3: Whisk the Glaze

• In a separate small bowl, combine the powdered sugar, milk, vanilla extract, and almond extract.

• Whisk the mixture vigorously until it is entirely smooth and pourable.

Step 4: Assemble the Lava Layers

• Once the bundt cake is completely cooled, carefully slice it in half horizontally to create two layers.

• Spread or pipe a generous layer of your banana frosting onto the bottom cake half, lightly toast it with a kitchen torch to prevent running, then gently replace the top half of the cake.

• Pour or evenly “paint” the smooth glaze across the top of the cake, then place it in the refrigerator for 20-30 minutes to set completely.

Step 5: Frost and Torch the Top

• Slather the remaining mountain of fluffy 7-minute frosting completely over the outside and right into the center hole of the cake.

• Fire up your kitchen torch and carefully brown the frosting all over until it has a gorgeous, toasted marshmallow finish.

Tips for the Best Old Fashioned Banana Pudding Lava Cake

1. The Sinking Banana Trick: Make sure to give your fresh banana slices a very light dusting of flour before tossing them into the batter. This absorbs excess surface moisture and prevents them from sinking straight to the bottom of your pan!

2. Clean Utensils for Meringue: Even a microscopic drop of fat can ruin your frosting. Rubbing down your bowls and beaters with a little fresh lemon juice ensures your egg whites whip up into perfectly stiff, beautiful peaks.

3. Embrace the Skillet or Bundt Flow: Let that frosting pool deep down inside the center hole of your cake. It creates that wonderful hidden pocket that turns into a luxurious lava flow the exact second your knife cuts a slice!

Why This Dish Is So Special

This cake is pure, sweet nostalgia wrapped up in a show-stopping presentation that brings out the inner child in everyone around the table. It has the comfort of the banana pudding bowls passed around at every family reunion, but with an exciting, elegant theatricality that makes your guests gasp when the center starts to pour. Baking this beautiful treat fills my whole home with the heavenly aroma of warm vanilla, rich butterscotch, and sweet bananas, turning any simple gathering into a warm, cherished memory.

Serving and Storing

• Serve Room Temperature or Chilled: Slice into this masterpiece while the frosting is freshly torched, or serve it slightly chilled from the fridge for clean, beautiful cuts.

• Store Leftovers: Because of the fresh banana puree and egg whites in the frosting, you’ll want to cover any leftover cake tightly and store it in the refrigerator for up to 3 days.
