Mummy Cakes with Jammy Guts

October 9, 2025 By Gretchen

Jump to Recipe Jump to Video Print Recipe
This recipe contains a sponsored ingredient! Check out Silda’s Jam for the best refined sugar free jam around!

Let’s have some delicious fun today! Mummy Cakes filled with Jammy Guts

Once again I have teamed up with Silda’s Jam for a healthier lower sugar option for your treats!

Mummy Cakes

Mummy Cakes are stuffed with the best bloody strawberry jam there is!

Silda’s Jams are made with maple syrup not refined white sugar!
So rather than a mouthful of sugar you are getting a burst of fresh fruit in every bite!

Mummy Cakes

I’ve also implemented my lower sugar cake recipe for the cake!

But you can of course take the easiest route and grab a Duncan Hines White Box Cake!
Duncan Hines Cake mixes are vegan and I have used their White Cake Box Mix by implementing my “Box Cake Hack” method
Following the same revisions as listed for the Yellow Box Cake on that recipe post
Reduced sugar buttercream is the icing on these mummy cakes for a really delicious treat that everyone will love!

Notes for Success:

Using monkfruit sugar as a one to one sugar alternative is my choice for baking cakes. 
Check out my Sugar Free Baking article with video comparison here

Listed below in the ingredient section I have substituted half of the granulated sugar for Monk Fruit Sugar
But you can use all granulated sugar if you prefer

Additionally I have replaced half of the original oil amount with applesauce
Again you can use all oil or vegan butter (melted) if you prefer in the total amount of 18 Tablespoons

Instructions

  • For the mummy cakes preheat the oven to 350°F & lightly spray your Twinkie Mold with pan spray
  • Place all of the dry cake ingredients including the sugar(s) into a large mixing bowl & whisk to distribute evenly
  • Add all the wet ingredients including the applesauce into the dry ingredients & whisk smooth. Continue whisking for about 40 strokes to develop the batter
  • Scoop batter with a 2 ounce cookie scoop evenly between the greased cavities of the Twinkie mold
  • Bake in a preheated oven at 350°F for 18-20min or when a toothpick inserted into the center comes out clean.
  • Cool the cakes in the pans until you can safely flip them onto a cooling rack to cool to cold

  • Watch the video tutorial for how to fill the cakes with jam & decorate the mummy cakes

Notes

Bob's Red Mill is my egg replacer of choice but you can use any brand you prefer
I have substituted half of the granulated sugar for Monk Fruit Sugar but you can use all granulated sugar if you prefer Or see my link for Sugar Free Baking above the recipe section
Additionally I have replaced half of the original oil amount with applesauce but again you can use all oil or vegan butter (melted) if you prefer in the total amount of 18 Tablespoons
Storage Mummy Cakes can be kept at room temperature for up to 1 one, but they are easier to handle when they are in the refrigerator
They will keep fresh in the refrigerator for up to 1 week

    Your creativity and multiple easily explained options to make these lower sugar and vegan are the best. Plus you are so right about how good Silda’s jams are. They make great gifts too.
