This toffee crumb cake is my go to dessert when I want something impressive but don't have hours to spend in the kitchen. With just 20 minutes of prep and 35 minutes of baking, you'll have a stunning cake that tastes like you've been working all day. I love using oat flour in the crumb topping because it adds natural fiber while keeping everything wonderfully tender. The combination of toffee bits and brown sugar creates this incredible caramelized flavor that feels indulgent without breaking the bank. Best of all, most of these ingredients are pantry staples, so you probably have everything on hand right now.

Instructions
- 1
Preheat the oven to 180°C. Grease a 20cm round cake pan and line the base with parchment paper.

In a medium bowl, whisk together the flour, baking powder, salt, and oat flour.
Tip: Make sure to sift the dry ingredients to remove lumps.
- 3
In a large bowl, use an electric mixer to beat the butter and sugars until light and fluffy.
Tip: Take your time and ensure the mixture is well combined.
- 4
Beat in the eggs one at a time, followed by the vanilla extract.
Tip: Scrape down the sides of the bowl to incorporate all the ingredients.
- 5
With the mixer on low speed, gradually add the flour mixture and mix until just combined.
Tip: Don't overmix, or the cake will become dense.

Melt the toffee bits in a double boiler or in the microwave in 30-second increments, stirring between each interval.
Tip: Once melted, let the toffee cool slightly before adding it to the cake.
- 7
Fold the toffee bits into the cake batter until well combined.
Tip: Be gentle to avoid deflating the batter.

Transfer the batter to the prepared cake pan and smooth the top.
Tip: Make sure the batter is evenly distributed for a smooth crumb.

To make the crumb streusel, mix together the brown sugar, oat flour, and chopped almonds in a small bowl.
Tip: Use your fingers or a pastry blender to work the mixture until it resembles coarse crumbs.
- 10
Sprinkle the crumb streusel evenly over the top of the cake.
Tip: Make sure to cover the entire surface for an even crumb.
- 11
Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Tip: Rotate the cake halfway through the baking time to ensure even browning.
- 12
Remove from the oven and let cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
