  • ½ cup (1 stick; 113 g) unsalted butter, at room temperature, cut into pieces
  • cup (131 g) sugar
  • 2 teaspoons vanilla extract
  • 2 large eggs, at room temperature
  • 1 ¾ cups (254 g) low FODMAP gluten-free all-purpose flour, such as Bob’s Red Mill 1 to 1 Gluten-Free Baking Flour
  • 2 teaspoons baking powder; use gluten-free if following a gluten-free diet
  • ½ teaspoon salt
  • 1 cup (240 ml) lactose-free whole milk, at room temperature


  1. Position rack in center of oven. Preheat oven to 350°F (180°C). Coat the insides of an 8-inch (20 cm) square cake pan with nonstick spray; set aside.
  2. For the Streusel: Melt the butter in a large microwave safe bowl. Whisk in the sugar, cinnamon and salt then stir in the flour until clumps form; set aside on a piece of parchment. No need to wash out bowl (the streusel should come out of the bowl very cleanly).

  3. For the Cake: Using same bowl, melt the butter, then whisk in sugar and vanilla. Now whisk in eggs one at a time. Add flour, bajing powder and salt and begin to stir/fold everything together with a sturdy wooden spoon or silicone spatula until partway combined. Add milk, switch to a whisk and continue to beat until you get a fluid batter.

  4. Scrape about half of the batter into the prepared pan (you can do this by eye). Scatter about ½ cup of the streusel evenly over the batter, squeezing it into clumps as you go (this is about a handful). Top with remaining batter, gently spreading into an even layer. Top evenly with remaining streusel.
  5. Bake for about 25 to 35 minutes or until a toothpick shows a few moist crumbs clinging. The cake will have begun to come away from the sides of the pan and the streusel will be golden. Cool on rack for at least 10 minutes. Cut into a 4 by 4 grid to make 16 servings and serve warm, or at room temperature. Cake may be stored at room temperature overnight, well wrapped with plastic wrap.




• You may add ½ cup (50 g) chopped walnuts or pecans to the streusel.
• Add ¼ to ½ teaspoon cardamom to the streusel.
• Add ½ cup (90 g) fresh blueberries to the flour as you fold it into the batter
• Add 2 teaspoons grated orange or lemon zest to the batter.
• Add ½ cup (43 g) sliced almonds to the streusel and ½ teaspoon almond extract to the batter.

FODMAP Information

Our recipes are based on Monash University and FODMAP Friendly science.

  • Butter: Both Monash University and FODMAP Friendly have lab tested butter. Monash states that a low FODMAP Green Light portion is 1 tablespoon or 19 g and also states that “butter is high in fat and does not contain carbohydrates (FODMAPs)”. FODMAP Friendly gives it a “Pass” at 1 tablespoon or 19 g. Both recommended serving sizes are presented as part of healthy eating guidelines, not as maximum FODMAP serving size. Fat can affect guy motility and trigger IBS symptoms in some people. Eat to your tolerance.
  • Sugar: Monash University and FODMAP Friendly have both lab-tested white, granulated sugar. Monash states that a Green Light low FODMAP serving size of white sugar is 1/4 cup (50 g). FODMAP Friendly simply states that they have tested 1 tablespoon and that it is low FODMAP. Regular granulated white sugar is sucrose, which is a disaccharide made up of equal parts glucose and fructose. Sucrose is broken down and absorbed efficiently in the small intestine.

Please always refer to the Monash University & FODMAP Friendly smartphone apps for the most up-to-date lab tested information. As always, your tolerance is what counts; please eat accordingly. The ultimate goal of the low FODMAP diet is to eat as broadly as possible, without triggering symptoms, for the healthiest microbiome.
