Don’t let the cake cool before frosting. I made this mistake once, and the frosting just sat on top like a heavy blanket instead of soaking in. You must pour the warm frosting over the warm cake for that perfect texture.
Don’t use a different pan size. A 9×13 pan is too small and will result in an undercooked center or overflow. The 10×15 jelly roll pan is essential for the right thickness and baking time.
Don’t skimp on the pecans or caramel. They’re what make it a “turtle” cake! The chopped caramel candies create little pockets of chewy caramel throughout the frosting. If you only have sauce, drizzle it over the frosted cake.
Serving Suggestions
I love serving this cake right from the pan, still slightly warm. The frosting will be gloriously soft and gooey. I just cut it into squares and serve with a big scoop of vanilla ice cream on the side. The contrast is heavenly.
It’s the perfect potluck or party cake. I bring the whole pan, a stack of plates, and a spatula. It’s always one of the first desserts to disappear. For a neat presentation, I sometimes sprinkle a few extra pecan halves on top after frosting.
For a casual family dessert, we eat it straight from the pan with forks. A tall glass of cold milk is the mandatory beverage pairing. It’s rich, so small squares are usually perfect.
Variations & Customizations
For a “German Chocolate” twist, use sweetened shredded coconut instead of the chopped caramel in the frosting. It’s a delicious variation my family loves.
Try using walnuts instead of pecans if that’s what you have on hand. They still give that great nutty flavor and crunch.
For a boozy adult version, add a tablespoon of bourbon or dark rum to the frosting along with the vanilla. It complements the caramel beautifully.
How to Store, Freeze & Reheat
Store any leftovers covered tightly with plastic wrap or in an airtight container at room temperature for up to 3 days. The frosting will firm up but stays delicious.
You can freeze the unfrosted cake. Let it cool completely, wrap the whole pan tightly in plastic and foil, and freeze for up to 2 months. Thaw, warm slightly in the oven, and make fresh frosting to pour over.
You can also freeze frosted squares. Place them on a tray to freeze solid, then wrap individually. Thaw at room temperature. The frosting may weep slightly, but the flavor is still great.
