Optional step if you want a salted caramel flavor: Combine all the dulce de leche in a bowl with a pinch of salt in a medium bowl. Stir well.
Spread about ⅓ cup of dulce de leche over each wafer (exact amount needed per wafer will vary based on the wafer size, no need to measure exactly), gently pressing down with a spatula to get the caramel filling into all the nooks and crannies of the wafer, making sure to get the edges too.
Top with another wafer, and repeat until you have 6 layers of wafer + dulce de leche. You can definitely make a smaller or taller cake by using fewer or more wafers!
Melt a scant ⅓ cup of the chocolate in the microwave, 30 seconds at a time, stirring in between. (I needed 45 seconds total). Stir in 2 teaspoons of coconut oil.
Drizzle the melted chocolate all over the cake. Optional: grate some chocolate and sprinkle that on top. Allow the cake to rest overnight in the refrigerator or a cool location so the dulce de leche soaks into the wafers. Slice and serve at room temperature.
This cake is best prepared 1 day ahead so the dulce de leche has a chance to soak into the wafers
I recommend getting an extra container of dulce de leche just in case you run out
I recommend getting an extra package of wafers, in case one gets broken or you want to make a taller cake. Tip: If a wafer breaks cleanly, you can still use it in one of the middle layers, since the dulce de leche will glue the cake together. No one will be able to tell the difference. If a wafer gets smashed and is missing pieces, you might want to use a different one (dip that wafer into melted chocolate as a snack!!)
Use leftover dulce de leche to dip apples, or stir into oatmeal
The nutritional information is an estimate and will depend on the actual wafers and amount of dulce de leche you use.Make your own Dulce de Leche in the Instant Pot: Make sure you start with sweetened condensed milk, not evaporated milk.
Remove the labels from the cans of condensed milk. Inspect the cans to make sure there are no dents or dings in them. If there are, use a different can of condensed milk.
Place the cans on their sideon the wire trivet/rack in the Instant Pot and fill the inner pot with water well above the top of the cans but below the max fill line.
Close the Instant Pot, set the valve to sealing, and cook on the manual setting at high pressure for 10 minutes.
Allow for natural pressure release, then carefully open the Instant Pot and allow the water to cool down until comfortable to the touch.
Remove the cans from the water. Open one can at a time (in case you don’t use the second one right away!). Stir the dulce de leche or process it in a blender for a few seconds to get it to be nice and creamy.
