Ingredient Notes and Substitutions

ingredients needed to make cookie butter cake in a bowl with labels.

Biscoff: ​You can find this near the peanut butter at the store. If you can’t find Lotus Biscoff, you can also use Speculoos Spread from Trader Joe’s which is the same thing.

Lotus Biscoff cookies: You can find them in the cookie aisle! You will use the cookie crumbs in between the layers for extra flavor and a crunch.

Whole milk​: This ingredient keeps the layers super moist and gives them a rich flavor. I don’t recommend using plant-based milk or the layers will be dry.

Sour cream: This ingredient keeps it moist for days! It can be substituted with full-fat plain Greek yogurt if needed.

Cake flour: For a tender and delicate crumb, this recipe is made using the reverse creaming method (like my mimosa cake and ding dong hostess cake). This requires low-protein flour and can not be substituted!

Tips for the Best Biscoff Cake

  • Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the “metric” button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
  • Use room temperature ingredients: Using room temperature ingredients creates a smooth, fully blended batter that will result in a uniform texture and even baking.

Storage and Freezing

​Store leftover slices wrapped in plastic wrap in the fridge for up to 5 days. To store it whole, keep it in an airtight container.

To freeze it for later, first, freeze it whole. Then cut it into slices and wrap them individually in plastic wrap. Store them in a freezer bag or airtight container for up to 1 month!

Notes

Step-by-step process photos are provided above, in the body of this post.
*Measure your flour properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*

  1. I tried baking this but the outside crust burnt and the inside didn’t cook at all. Similar to a previous comment it was just entirely gooey and it tasted so sour but I followed the recipe to the T. What happened?

    1. Hi Jenny, it sounds like your oven is way too hot. Try turning the temperature down.
