Vegan Pretzel Toffee Cake

Introducing a delightful layered cake that combines simplicity with a touch of charm! :) 

The base is made with oats, so it has a gentle crunch instead of a heavy, buttery crust. The middle layer is blended until smooth and creamy, with a naturally sweet, toffee-like taste. On top, there’s a light chocolate layer that holds a mix of walnuts and pretzels, giving you a bit of crunch and that sweet-and-salty balance.

It’s the kind of cake you can make ahead, keep in the fridge, and slice when you want something a little sweet but still on the lighter, more wholesome side. 

No complicated techniques, no special equipment, just a simple, layered dessert that fits well into a healthier way of eating.

  • Pinch of salt


Topping

  • 15–20 g pretzels, lightly crushed

  • 10–15 g walnuts, chopped


Instructions

1. Crispy Base

  1. Preheat the oven to 180°C / 350°F.

  2. In a bowl, mix oats, ground oats, erythritol, salt, plant milk, and crushed pretzels.

  3. Press the mixture firmly into the lined pan.

  4. Bake for 12–15 minutes, until lightly golden and set.

  5. Remove from the oven (do not cool completely).


2. Toffee Layer

  1. Blend tofu, sweet potato, erythritol, vanilla, cinnamon, salt, and ground oats until smooth and thick.

  2. Spread evenly over the warm oat base.


3. Chocolate Layer

  1. In a small saucepan, whisk cold plant milk with starch until smooth.

  2. Add cocoa, erythritol, vanilla, and salt.

  3. Heat gently, stirring constantly, until thick and glossy.

  4. Pour the warm chocolate layer over the toffee layer.


4. Topping & Final Bake

  1. Sprinkle pretzels and walnuts on top, gently pressing them into the chocolate.

  2. Bake at 175°C / 345°F for 30–35 minutes.

  3. The center should be set but slightly springy.


5. Cooling

  • Cool for at least 40 minutes, then refrigerate for 1 hour before slicing.


Notes

  • The crispiness comes from not blending the base; texture matters.

  • Finely ground oats create chewiness without dryness.

  • This cake firms up as it cools; don’t judge it straight from the oven.

  • For extra crunch, slightly toast the walnuts before adding.
